Can Ubuntu Linux Consume Less Power Than Windows?

An anonymous reader writes "Now that the big Linux kernel power regression has been solved it looks like Ubuntu 11.04 can compete with Microsoft Windows 7 in terms of overall power usage. New tests revealed by Phoronix show the power consumption of Ubuntu 11.04 vs. Windows 7 operating systems. On a range of different systems, the power consumption of the Linux OS was comparable to that of Windows except for a few select workloads and systems."

Again, ignoring the technical specifics of "power" vs "energy" ... from their perspective, if you pull in the power to put it into a battery, it's consumption. The fact that it's available for later use is largely irrelevant.

If I buy a gallon of gas and put it into a red plastic can, that doesn't mean that from the pump perspective, I didn't just 'consume' a gallon of gas.

"Can" is not "Does"

[Kagetsuki]

It is possible it could consume less power, but that doesn't necessarily mean it always does. Different hardware, specialty drivers, default settings vs tweaked settings - come on?

Re:"Can" is not "Does"

[MacGyver2210]

That applies for all computers too, though. I can get a lot better power use out of even Windows with the right power settings and usage.

Given the same settings and usage pattern, I find that my linux computer uses about half the power (twice the battery life).

Re:"Can" is not "Does"

[Noughmad]

Could you tell us what kind of hardware do you have and what software do you use?

I'm really interested, because my new HP ProBook can barely run 2 hours on battery on Linux with a light load, but the specs said 4-4.5 hours. Now I know they're lying and that I could stretch the life by totally dimming the screen, but I doubt they would claim twice the battery life. It was even worse before I installed the proprietary graphics driver by AMD, so I presume there are some bad drivers here. On the other hand, my girlfriends ThinkPad Edge with an AMD processor easily playes compressed video for about three hours. She's running Kubuntu while I have Arch, both with KDE desktop. Unfortunately, neither of us have Windows installed so I can't compare with that, and I don't feel like installing Windows just to test battery life.

Re:"Can" is not "Does"

[cpricejones]

From personal experience (my Toshiba laptop), I noticed that Ubuntu consumed more power than windows Vista (based on how long the battery would last). I tried to tweak both of them to run on more optimal settings for battery life. I probably did a poorer job tweaking the Ubuntu settings though due to my own lack of experience with the OS. This was running the same basic programs in both OSes (office programs like powerpoint/word and the openoffice equivalents, mozilla/firefox with lots of tabs open)--not particularly taxing on the CPU IMO but a fair measure of what I actually use my laptop for. Important to say again that this was Vista, not 7. So, even my attempts to optimize did not succeed on the part of Ubuntu in what I consider to be a fair assessment from a beginner to moderately skilled user.

Re:"Can" is not "Does"

[Anonymous Coward]

arch doesn't have cpufreq set up by default, try setting the ondemand or conservative governor and you will get better battery life.

Re:"Can" is not "Does"

[gl4ss]

the programs that run are which matter as long as there's not any crazy showstopper bugs that just don't let things sleep as well in either os. and the programs aren't that different, despite the old gentoo joke about some guy who was pimping on forums how he had built his firefox without ps/2 keyboard support.

Re:"Can" is not "Does"

[Kagetsuki]

I get really clean font rendering actually (using Ubuntu and Compiz). There's a tool to change how the fonts are rendered as well but I haven't really touched it - the settings are all defaults. What are you comparing to?

Re:"Can" is not "Does"

[jones_supa]

Now I know they're lying and that I could stretch the life by totally dimming the screen, but I doubt they would claim twice the battery life.

Oh, it isn't even rare that manufacturers claim inflated runtimes for batteries. Many times they are reported of ideal conditions, like having screen dimmed down and the machine just idling. I'm not saying that your Linux might still not be wasting power.

Can it crash less often than Windows?

[spiffmastercow]

Ever since I upgraded my netbook to Ubuntu 11.04, it crashes randomly and often. I'm talking more that Windows 95 with no patches. Hell, more than Windows 3.0. While solving power management would be nice, it's a moot point if the computer is always off because I can never use it.

Re:Can it crash less often than Windows?

[Andy Dodd]

11.04 seems to include a kernel with LOTS of regressions, or the Ubuntu maintainers added some to the kernel/modules packages.

For example, the wireless drivers for Ralink RT2860 chipsets were rock solid from 9.04 to 10.10, but were completely broken after an 11.04 update. Even after doing some module blacklist magic, the wireless drivers now perform horrifically and fail to connect very often.

Re:Can it crash less often than Windows?

[erroneus]

You know seriously, I used to have crashing problems like pretty much everyone else but two things have changed:

1. My use of Windows is limited to "what I need." I don't install crap of any kind. If I don't use it, it doesn't get installed or will soon be removed if it was there.
2. Windows uptimes have increased for me over the years. Perhaps it's all the bug fixes and what have you, but whatever the case, I don't have as many problems. (Other users, however, still seem to have the same problems, so it's not all to Microsoft's credit.)

As far as Ubuntu on a netbook? Look to the quality of your hardware. I have run Ubuntu netbook edition without problems at all.

Re:Can it crash less often than Windows?

Well, I don't know what problem spiffmastercow had, but this bug has been around since the launch of 11.04, and crashes my laptop on a regular basis.

Re:Can it crash less often than Windows?

[Anonymous Coward]

I have a 3 yr old Asus eeebook with a whopping 4 gb SSD. I have run Ubuntu Netbook remix, updating it yearly. In my memory, it has never crashed. Early on, there were power consumption issues but they disappeared with the first update. For the last few months I have been running regular Ubuntu (with the phase out of the netbook version) and had to delete some stuff to get free space on the SSD. With a nearly full hard drive, performance was very poor and eventually locked up the machine. Since my little deletion party, however, performance is again acceptable and there have been zero crashes.
If your machine is crashing "randomly and often" and it's not broken somehow, then it must have some strange unknown-to-Linux hardware. I'd bet you could get some help on the Ubuntu forums.

Re:Can it crash less often than Windows?

[Stewie241]

Would be interested to know how you did updates. I always had problems with insufficient space to install the updates and such. Is there a trick?

Re:Can it crash less often than Windows?

[Pausanias]

It may not be the hardware. Non-LTS Ubuntus are full of regressions. Affects some significant minority of users, but not enough to affect ship date.

The worst regressions are always fixed in the next release. They are rarely backported to non-LTS, a strategy which is designed to keep you constantly upgrading. Except that once one regression is fixed, more creep up. If you're lucky, your won't be affected. But there are ALWAYS regressions.

I basically treat non-LTS Ubuntus as betas for the LTS. I don't expect them to work. I expect many things to be broken. Many of the regressions are insidious---you don't discover them until later in the game. And, dirty secret is that once LTS is long in the tooth, only security updates get backported to LTS. Got a non-functioning file open dialog? Too bad, not going to backport the fix to LTS, you can rot in hell or upgrade. (read the final few comments, where the dev tells me I need to upgrade from LTS to non-LTS to get back a functioning file open dialog box.)

Bitter much? Yes I am, for a fan that's been with them for 7 years now.

Re:Can it crash less often than Windows?

[MrEricSir]

And while that shouldn't happen at all, at least with Ubuntu you can often recover from such a state by switching to a terminal and restarting Compiz and/or X. Not the case with Windows.

Re:Can it crash less often than Windows?

[Anonymous Coward]

How did you manage to do that? Is it a hardware problem? I've been running Ubuntu 11.04 for several months (since the time it came out). Has never ever crashed. Not.once.ever. Does crashing mean 'I pulled the power plug and the batteries were out and all of a sudden it just crashed'? Your problems I fear are unique to you.

Re:Can it crash less often than Windows?

Alright.. It's an Asus EeePC 1001H with the dual SSDs (4GB fast SSD, 16GB slooooooow SSD). Worked great on 10.10. Now it hangs every 5 minutes, and drops connection to the wifi router every 5 seconds. Completely unusable. Now I have to go look for a new netbook distro, since they've turned Ubuntu into a steaming pile of shit.

Re:Can it crash less often than Windows?

So my hardware magically broke at exactly the moment I upgraded to 11.04? Methinks not.

Re:Can it crash less often than Windows?

[mcelrath]

I've been having kernel panics regularly, I recently figured out that it's due to "hardware acceleration" in the binary flashplayer, coupled with the open source video drivers (ati, for me). Right click on a flash animation and turn off hardware acceleration. And/or un-install that steaming pile of dung. Still, it shouldn't be causing kernel panics. I think the open source/drm drivers need work.

I love how everyone immediately assumes it's a hardware issue, when I clearly specified that the problems only started when I upgraded to 11.04. Again, it worked fine on all previous version of Ubuntu (down to 10.04), but took a shit when I upgraded to 11.04. But rather than acknowledge the problem, all the linux fanboys just put their fingers in their ears and shout "hardware problem" at the top of their lungs.

I've been using Lubuntu 11.04 on my Asus S101 EeePC with the 32GB SSD, and it has been great. Way more responsive than standard Ubuntu. And more stable.

How the hell do you people manage this. My netbook is stable, has ran through two upgrades, hardly ever crashes, and the life on batter was rather good (until 11.04, but that's understandable). And while I tweak my main machine, the netbook is basically clean of any modifications (don't want to bother). So it's definitely something you are doing.

Likewise when someone says it runs like a POS they should explain what hardware they're using since it is likely the problem and then someone can look into it. Better yet he reports as much detail about the problems and the hardware to the bug tracker and it will benefit him and many others with the same hardware. He may also find he had dodgy hardware and the OS is irrelevant so he could end up saving himself a lot of hassle.

Re:Can it crash less often than Windows?

[Anonymous Coward]

It's not even 'think' at this point, they *DO* need a huge amount of work, and it's not just the ATI drivers either, it's intel and possibly nouveau as well. I ran into a bug a few months back involving memory banking on HD4xxx series hardware. Turned out testing had only been done on 5xxx series hardware and the bank switching method used worked there but caused memory corruption/crashes on the previous generation of hardware. This bug had managed to last from the drm module in 2.6.32 (I believe, might've been .28) all the way through to the .38 release candidates. Point is: There's a huge amount of work going into 'updating mesa' to support newer technologies, but the regression testing is either limited or non-existant and thus not testing the fringe cases where real world software often resides. Additionally R100/R200 hardware has a variety of bugs/glitches spread through both the 3d and 2d drivers which seem destined to remain unresolved (Not that I can complain, but trying to juggle working versions of X/desktop enviroment/kernel/userspace has become as cumbersome as trying to retain full functionality in all windows apps as you upgrade versions and install directx/servicepack upgrades.)

I've personally reverted to 2.6.36.2 and switched over to the proprietary ATI driver.

Since this is Slashdot, I have to ask what retarded definition of recover are you using?

"OMG the kernel was still running but because X died all my apps died and I lost all work that wasn't saved. Yay ! Go Linux CLI !!"

Crashing X is no more worse than crashing the entire system for the majority of desktop scenarios. Besides which you can tweak linux to boot extremely quickly. So you don't save much time anyway. The kiosk project I worked on the last time around booted in under 10 seconds (from grub to X) using readahead, concurrent initscripts, pre-populated /dev etc..

That's interesting. My workstation at work is running Ubuntu 11.04 and hasn't had a single issue at all. I do Android development for a living and when I first got this job, they plunked me down in front of a shiny new Win7 box.

I gave it the old college try for two months but finally, after gritting my teeth for the last time, I made a beeline for the blank CD's and had Ubuntu installed over my lunch break.

Now, I can finally be productive with great tools integrated into the OS. SSH, bash, apt-get, tilda, vi, and most of my dev environment just an apt-get install away. Not to mention that the devices I work with (acer iconia a500, motorola xoom, nexus s) have the drivers built in for a drama free plug and play. If they tried to make me go back to windows, I'd resign on the spot.

There is something wrong with your computer hardware. As much fun as it was to point out older versions of Windows crashing, Windows 7 is solid as a rock on the stability front.

Things in life ought to progress, i.e. get better. This is especially true with FOSS. Software ought to get more stable, have more bugs eliminated over time. It's truly sad that basic software functions like file open dialogs get torn out and rewritten from scratch so much that the actual number of bugs in everyday functionality seems to remain relatively the same.

I suppose it's the usual emphasis on the shiny rather than the worky.

Which will save power. The gfx card, as it happens, is rather good at doing window translation and compositing in hardware, seeing as that's what we use it for. A properly-designed gfx card (in a low-power state) and compositing WM should blow the pants off of a CPU solution. I don't know if this is the case (it depends on how far back an unloaded GFX card will throttle) but I wouldn't be super surprised

Re:Heh

[Anonymous Coward]

All of my desktop graphics cards run at the lowest clock (50 MHz graphics, 135 MHz memory, 101 MHz processor or thereabouts) in KDE 4 at a resolution of 1680x1050 with composting enabled. For reference, those are 1997-level operating frequencies you would've found on a PCI graphics card.

Composting does not consume more power, Aero only does because it's built on top of a bulky DWM which is meant for usability, not performance. The whole purpose of Aero has always been to solely make the user experience on Windows Vista and Windows 7 easier. If resources were an issue, the recommended amount of VRAM for it would not be 128MB. In contrast Compiz and KWin run on 32MB or less VRAM, and put a far lesser strain on the graphics card depending on what you have enabled.

So which graphics hardware and window managers / desktop environments do you use on Linux then? It doesn't really matter how good the gfx chip is if Linux can't use it effectively.

For a desktop, it does cost you more to use more electricity. I'm not sure that it should be the only consideration, but now that my laptop can do most of what I want to do, there's no real reason for me to have a desktop other than gaming. The desktop at peak uses about 450 watts of electricty, granted it rarely if ever gets there, but then there's the monitor's use of energy. By contrast my laptop maxes out at 25 watts plus whatever electricity is wasted by the transformer.

Consequently, I might not even bother to replace my current desktop when it ultimately fails, seeing as most of the games I like to play run just fine on my laptop.

Noticed Ubuntu runs cooler...

Install the AMD Cool n' Quiet (or whatever they call it now) "drivers".
Then, in Windows, set your power profile to "Minimal Power Management".
This lets the CPU underclock itself, turn idle cores off, etc.

Thanks, but I do that already (in 7 and Ubuntu). Idle is probably more in the 26-32 range for 7 but still about 10 deg hotter than Ubuntu.

It just hardly ever "did", at least for me. For example, the Asus 1001p was advertised with an 11-hour battery because it shipped with Windows. If shipped with Ubuntu, it can only be advertised as having a 6-hour battery.

RTFA. Power management in the Linux kernel has changed since you looked at that.

Re:Of course it "can"

That's frequently because of proprietary drivers and APIs to manage the power. My Thinkpad gets five to six hours of battery life, and the utility for stretching it only works under Windows, which means that I have to give that up if I want to run Linux on that particular computer.

There's the rub.
Without Intel or AMD's CPU "drivers", you won't be able to get the Cool n' Quiet / EIST / whatever shit that underclocks your CPU and disables idle cores.
Intel's drivers are built into every Windows version since XP SP2, but they won't be the latest version.
AMD's drivers aren't built in, that I know of (I don't have an AMD Windows 7 system to test with).

And then you have to set your power scheme to "Minimal Power Management" to enable that shit.

Color Me Skeptical

[Bacon Bits]

I've run Debian derivatives going back to '06 on my laptops -- an HP, a Dell, and a Samsung (this was the point at which I could install Linux and not have to spend the next several hours getting the network card and wireless card to work with my existing hardware). However, I found that Linux consistently cut my laptop power by about 20-30% over Windows XP. Vista was worse, of course, as that had serious power issues on laptops at first, but now Windows 7 performs as good as or better than XP, as near as I can figure. Still, I still find a consistently shorter battery life on Linux on my laptops.

This isn't data of course, and I'm sure others will have had the opposite experience, but it is my experience with my hardware. I never did try any of the kernels which had this power regression, however. I have been working on projects which require PowerShell and Office, so all my recent activity has been in Windows.

Re:Color Me Skeptical

Can I colour you annoying? Nonsensical expressions like that one fuel my e-rage.

Re:Color Me Skeptical

I suspect this is because, as found by Phoronix, Linux is unable to turn hardware off when it is not in use. This thanks to buggy ACPI or similar that the OEMs work around in their own drivers for Windows, but that the Linux devs have to find out about the hard way. Hell, not too long ago there was a desktop motherboard that was unbootable if Linux was honest about itself. This thanks to a garbage ACPI entry for anything other then Windows.

Re:Color Me Skeptical

Do you find the same trend to be true just for hard disks? I've got a couple of Acer laptops and my wife uses hers for hours every day. And every day, the hard drive consistently reads >50 degrees C. I'm concerned that the hard drive will have a shorter life because of this.

Any suggestions as to what I can do? Would an SSD be better?

Thanks.

Re:Color Me Skeptical

[gottabeme]

Um, that's probably a matter of poor cooling in the Acer laptop. There might be a lower-power mode you could set with hdparm, but spinning the disk down completely just isn't practical: it gets spun back up too much. And a good SSD might cost more than the laptop is worth--certainly more than a new hard disk.

Buy a new hard disk if you want, one that's quiet and cool--but that's no guarantee it will be cool in your laptop.

My suggestion: back up your data regularly, set aside some money to buy a new disk when it fails, and be prepared for HDD failure.

No Aero?

The video hardware is more efficient at rendering than the CPU, so this could skew the results quite a bit by potentially having Aero off.

This is likely even more of a concern on the combination GPU/CPU systems where Intel/AMD are banking on the fact that you'll be rendering entirely on the GPU.

That depends.

[degeneratemonkey]

In my experience, it depends on the hardware to some extent.

For example, consider that newer laptop GPU setups (using NVIDIA Optimus and whatever ATI calls their equivalent) use "switchable graphics." Essentially the output device is always a cheap integrated device, but when real GPU power is needed the OS will seamlessly switch over to a separate, bona fide GPU and have its framebuffers forwarded to the integrated chip.

This requires kernel-level support for the switchable graphics systems -- support that does not exist in the Linux kernel.

Because of this, the GPUs in these systems constantly operate at full power despite never actually producing rendered framebuffers. This eats laptop batteries alive.

Re:That depends.

Fact is, ubunto 10.4 did worse than previous ubuntus.

Re:With or without Anti-Virus?

[magamiako1]

gl4ss:

It's not a matter of whether or not they included 3D Compositing on Ubuntu. In Windows 7, Aero is the default view for Windows and should be treated as such. Almost no computer with Windows 7 doesn't include Aero.

Unfortunately the article is worded as if they simply used out of the box software. Windows 7, and Ubuntu. But the reailty is, out of the box, Windows 7 uses Aero. If they turned off Aero, that's not an out of the box test and it should be noted as such.

Re:With or without Anti-Virus?

[cbhacking]

Most AV suites are active less than 1% of the time on modern systems. Yes, they do add *some* cost, but it's hardly likely to sway the results by much.

Besides, AV is not strictly required. If you know what you're doing and don't get particularly unlucky, you can get by for years without it. If you are sufficiently unlucky, you can get completely taken over even if you know what you're doing and run up-to-date AV as well. I run a free and non-obtrusive AV program, but if it started having a noticable impact on performance, including battery life, I'd kill it in an instant.

Power Consumed is the Least of my Ubuntu Worries

[gamrillen]

Whenever Canonical releases a new version of Ubuntu, I'm always game to take it for a test drive. I use an EeePC 1005HA netbook and a VirtualBox VM (Windows 7 x64 host) to do my testing. For the last three versions (10.10, 11.04, and 11.10) I've had issues with the netbook overheating and shutting down the hardware. Additionally, the sleep/hibernation functionality never seems to work just right. Sometimes, when I close the netbook, it won't go to sleep at all and the LCD screen will stay turned on. Other times, the netbook will sleep peacefully, but won't boot back up when I open the lid (as set in my preferences) or hit the power button. I have to remove the battery and do a hard boot. As for the VM, Ubuntu runs incredibly slow even with the guest additions installed. I have to sometimes triple click on single click buttons to select something, and Gnome likes to generate random error messages. On the flip side, I can run Windows 7 x32, Windows 7 x64, and even Windows XP x32 on the netbook, and won't have any of the issues I see with Ubuntu. The same goes for using the three Windows variants mentioned above in the VM. Yes, less power consumption is a great thing, and yes it's awesome that interface tweaks are happening to make it prettier, but until stability issues with fairly common chip-sets are resolved, I won't be using Ubuntu on a daily basis. However, Linux Mint, which is based on the most current stable release of Ubuntu seems to take all of Ubuntu's shortcomings and clean them up. Mint just seems... tighter. Everything flows better, and I don't see the glitches that I normally see in Ubuntu.

There are far more usable and frankly higher quality distros than anything that comes from Canonical.

I'll probably be shot down in flames but as a long term linux supporter (since slackware 1.1 on Floppies) I've seen it evolve beyond all recognition.
At first Ubuntu was a breath of freah air. It took the debian dinosaur and shook it alive. Now, they are changing things and IMHO not taking the user base with them. I know of at least 10 former Ubuntu fans who have jumped ship since 10.10 came out. The quality is just not there any more. Far too much is crammed into each release with little thought for fixing the bugs.
Non of their stuff seems complete. Or in agile dev speak, 'It is not done.'

Call it what you want but Ubuntu looks to be the de facto OS that represents the Linux desktop market. Even when I ask my friends who are not familiar with too many Linux distros , the first thing they can come up is "Ubuntoo". As such, like it or not, Ubuntu is the only OS that I can think of that has the resources and the organization structure to compete with Windows. However, with the recent changes following 10.10, it seems that they're beginning to lose the competition. That's bad news for every other Linux distro in the desktop market. When Ubuntu loses, the Linux community loses in terms of popularity and reputation.

To be more on point, perhaps I'll be shot down in flames with you, but you're clearly correct. Ubuntu is far from the best ("highest quality") desktop distro, and it doesn't really make for an ideal server OS either, in light of the great Linux-based alternatives. I'm glad Canonical and Ubuntu exist because some of the projects they work on which set them apart may actually have broad appeal and be good for the "community" in the long run, but it is too bad it's them who have become synonymous with what [less-informed] people refer to as "Linux." People may not realize there are better alternatives, like these high-quality distros (in no particular order):

• ArchLinux
• Mint or just pure Debian
• Gentoo

Ubuntu IS linux and as far as I can tell, you can do pretty much the same on Ubuntu than any other system, it's just not very efficient at it. You're right, a lot of stuff isn't done and they are trying to go big but by doing that their releases are incomplete. They are trying to grab some of that Windows market but there's no point since you can't properly run Windows applications and there aren't any equals in the linux world. Coming from Redhat and CentOS, I can say that linux doesn't have any real world application outside from hosting servers and making certain people's ego's go off the chart. "Hey, I use Linux, so I'm superior than everyone else!" Sure, you can use Wine but that's not really good enough since it's broken more than half the time and it's extremely slow.

Before anyone here says there are windows equivalent, as a graphic designer, GIMP is a joke compared to Photoshop and you can't really open PSD files correctly. There aren't any decent video editing suite, and you'll never see something like 3D Studio Max, Maya, or Lightwave on linux. Open Office isn't horrible but it's definitively not near as good as Microsoft Office. I can go on and on and on, but my point is, is that Linux had its time in the sun years ago, but now it no longer serves purpose. People don't need an open source OS, they need open source apps and that's available on all systems. Sorry but Mac and Windows are the real winners here.

My test laptop has been hanging out, waiting for something new to fire up.

Re:Repeat after me, Ubuntu is not Linux ok

[keneng]

Ubuntu is Linux just as much as any flavor. I've been installing and running with Ubuntu since roughly 2004.(dapper or breezy). Sure I've had issues at times with certain things, but there hasn't been an instance where I couldn't find something someone else actually resolved before I could get my hands dirty. The Launchpad and associated Ubuntu knowledge base have always come through for me. I love Debian too. But give credit where credit is due. Ubuntu has gotten snappier over time when using the same hardware. NOTICEABLY SNAPPIER. HATS OFF TO UBUNTU.

To those other guys trolling here and bad-talking ubuntu, you should be grateful the Ubuntu flavor exists as an OS alternative to try and run with. It certainly doesn't stop you from installing and running other Linux flavors.

When I purchase a new box, the first thing I'm going to do is to install the latest version of Ubuntu, and give unity a whirl. If I don't like it, I'll resort to the GNOME GUI. But if they removed my GNOME choice of gui, I'll have to resort to Debian which is fine too. I'm grateful for all these alternatives that are not MS-WINDOWS because the world needs them. All of you should be grateful for this Linux variety too.

Re:Repeat after me, Ubuntu is not Linux ok

I don't think you use Ubuntu for the reasons that most people use Ubuntu. It is the user friendly version of Linux.

I prefer Craftsmen for my hand tools, Dyson for my vacuum, Hoover for my carpet cleaner, Cub Cadet for my grass cutting, Pennington for my seed/fertilizer needs, Dawn soap packets for my dishwasher and Aveeno & Fructus for my body. I don't see anyone screaming Jihad on their forums.

You want to know why! Because they are marketed and reliable brands that people know and use. Microsoft, Apple, Sony, etc. guess what they have in common? Years and years of quality products with sales that allow them to market themselves. If Shuttleworth's pockets are so deep then why doesn't the average person know anything about Ubuntu?

total fscking shit

[Anonymous Coward]

Ubuntu keeps adding bells and whistles for the unwashed masses. Pretty soon we will need a supercomputer just to run a word processor. What shit.

People, innovation has ended in PC's. It's like going from the model T Ford where you could buy a model T in any color as long as it was black. Ford provided a car that did the job and was reliable. We then got cars with dayglo colors and virgin pink. That's progress !!!!

Look at PCs shit on top of shit. NO real innovation just EYE candy. We are turning into a nation of IDIOTS.

You're getting confused by regular tubes. The Internet is made of special tubes that have an infinite number of sides. It's because there are so many sides it looks like it only has one side like regular tubes so it is an easy mistake to make.

TCP/IP stack

[DrYak]

They've already had chunks of BSD-licensed code in their TCP/IP stack.

The problem is specifically GPLed code like Linux, because GPL license requires that when distributing software made with it, you need to distribute the source of said software (the same way as source was distributed to you) so that the users can - if they wan - tinker with it (exactly like you did to make your own software out of it). GPL is "here's the code. Do whatever you want, provided that the next person in the chain gets the same freedom too".

Microsoft prefers either proprietary (because they can buy the code to use it - see Skype) or BSD. Because that one is "here's the code. Do whatever you want. We only ask you to mention us.".

Ok, some hardware needs extra parameters

[Marrow]

All hardware has VPD strings (vital product data) strings that will tell you what you have. Why cant they come up with a simple cheat sheet of default parameters for the hardware. Write some code that walks the bus from CPU out to the last usb dongle and if any gotcha hardware comes up, then its "magic numbers" get added to the boot parameters.
If the hardware is trustworthy, fine...no parameters. If not, then it gets the fixes it needs. Are these rules being hard-coded in now? Why edit a file in a million places to turn on something in grub. Add it to one place: the apt repository and then the next update the hardware profile parameters for mobo chip xyz version 6 mod 3 fix 2 get downloaded. If you have that exact thing, then it gets fixed.
You could have any number of these and they would not interfere with each other.

Re:Ok, some hardware needs extra parameters

[RobbieThe1st]

See, that would be great, except it doesn't work quite like that: Generally such hardware configuration would be entered into the driver, which works great... Until you end up with two or more pieces sharing the same VPD, but need slightly different handling rules. Or, what happens if a piece of hardware just plain lies about it's capibilities? That's the real problem, and it's hard to work around: Some driver may work perfectly well on the dev's device, but on someone's newer/older revision(etc.) it doesn't work quite right and crashes.
On top of that you have the issue of occasional flakey boards, so when you end up with an error like this, how do you detemine if it's the driver or the hardware, especially if you aren't in possession of the hardware yourself?

trolls

[Beelzebud]

Now it's time for the people insisting that there was no power regression, to admit they were wrong, and their attitude would have kept this bug swept under the rug if they had their way. I saw a few people trolling Phoronix for the past month saying this regression didn't even exist.

Re:trolls

[RobbieThe1st]

Of course, it *might* have not happened on their machines! AFAIK, it was due to some faulty bios tables, and only from some MFGRs. So, one same-spec'd model might not have the problem, and others might.

Re:Power Consumed is the Least of my Ubuntu Worrie

[rwa2]

Hmm, I was given the impression that stock Ubuntu is pretty dismal on netbooks. Try one of the netbook remixes that actually use the array kernel tuned for Atom chips and other netbook hardware.

My favorite was eeebuntu 3.0 , but it hasn't been updated recently while waiting for the devs to polish off their new Aurora distro.

I've also played with Fuduntu, which seems like a nice rpm-based distro, but my machine didn't survive a yum update. I might try again.

Then there's the Ubuntu Netbook Remix, which probably tracks the stock Ubuntu the closest, but I've never really played with it.

Ubuntu != only Linux distro

Ubuntu is not the only way to use Linux, I would recommend Debian if you are having problems with Ubuntu. Ubuntu is very closely related to Debian.

Title says "Less", Article says "Comparable"

[halligas]

"On a range of different systems, the power consumption of the Linux OS was comparable to that of Windows except for a few select workloads and systems." That sentence says power consumption was relatively the same, except when Windows consumed less. A little bias by the headline writer?

Re:Title says "Less", Article says "Comparable"

[RobbieThe1st]

I dunno... What I saw was close but slightly lower consumption on everything but the T61.

Linux 2.2 was better

[Billly Gates]

Linux has seriously regressed over the past decade. I remember when Linux was a lite alternative to Windows 2000 and had power management in software that was orders of magnitude better.

Those days are long gone.

I am sick and tired of playing with releases of Ubuntu and Fedora hoping this one will truly be unique and beat Windows. Last March I switched back to Windows 7 as I do not have time to tinker and fool around with older releases of gnome to avoid unity/gnome-shell, and trying to enable hardware GPU accelerated web browsing experience. If you want it to perform as good as Windows, then just use Windows.

Re:Linux 2.2 was better

[Anonymous Coward]

I think you're confusing linux with the various desktop environments which SUCK BADLY.

You have a choice. Openbox and blackbox are liberating, no bloat, no glamour. Just sweet sweet productivity.

Re:Linux 2.2 was better

[Anonymous Coward]

I'm scared that you're the real bill gates.

Re:Linux 2.2 was better

[hitmark]

The reason for this is that there have been a transition from APM to ACPI. The former leaves the details up to the OS, the latter have some kind of meta-language for "describing" the hardware capabilities. Sadly it was set up while MS was still doing their EEE thing, and so we have something that on paper should be a standard, but in reality only really work in Windows. The rest of the world have to second guess everything.

And EFI seems to be heading in the same direction...

Re:Linux 2.2 was better

[Anonymous Coward]

must admit that the wife got totally fed up with Ubuntu, so I had to switch her back to Windows 7. Im quite impressed with Win7. It's probably the best OS they've released. Very seamless. As for me, I jumped ship from Ubuntu to Fedora 15, because I really did not want to use a DM that had been in development for 1 year (yes, im exagerating), whilst Gnome 3 has been in development for a long, long time. Plus, I really like Gnome 3, and after having read the devs reasoning behind certain features, I am in total agreement with them.

I wanted to stop with a Debian based distro, and Ubuntu was always going to have the latest software: I really like Debians software catalog size, and it's ease of software installation. yum is still not on a par with apt, but Fedora just has it all: systemd, gnome3, latest btrfs support etc etc. It's hard to decide these days (for me) whether to do Fedora or Debian, because they have diverged quite much in terms of standard feature set.

I'm no Microsoft zombie, but LINUX should have been stomping on Microsoft all along in this category, and there really isn't much excuse for this. Sometimes the LINUX camp is more insular, defensive, and partisan than Apple folk.

LTS vs non-LTS

[AliasMarlowe]

I basically treat non-LTS Ubuntus as betas for the LTS. I don't expect them to work. I expect many things to be broken.

Yup, that's the truth: they are betas. I ran Warty and Breezy, but since Dapper (the first LTS), I've stuck with LTS releases on most of our boxes. Recently, I have not bothered installing non-LTS releases on any box; it just leads to too much grief. I have briefly looked at 10.10 and 11.04 on VMs, just the same way as I occasionally look at other distros.

Linux is not Gnome

[Anonymous Coward]

As punishment, I condemn you like Bart Simpson to scrawl N^X times, Linux is not Gnome (nor KDE). Really, Linux the kernel has improved with minor regressions between succeeding releases that are subsequently fixed. What you're talking about is the bloat that the supposedly popular distros add on top. Gnome isn't Linux. Hell you can even run it in Windows (and, yes, it runs slower there).

Well, down the line he also said that ...

On the flip side, I can run Windows 7 x32, Windows 7 x64, and even Windows XP x32 on the netbook, and won't have any of the issues I see with Ubuntu.

So it seems, that he is able to run a Win7 x64 on THE netbook (I guess it is the EeePC 1005HA). Quite an achievement.

Re:Power Consumed is the Least of my Ubuntu Worrie

Ok, point taken :) I do beleive VirtualBox is able to emulate 64 bit platforms on 32 bit hardware... though that must be horribly slow, and on a netbook that WOULD be an achievement.
