Ubuntu 11.10 Down To 12-Second Boot
deadeyefred writes "Even though it's still only in alpha, it appears as though the forthcoming version of Ubuntu, version 11.10, will be much faster than earlier versions, according to this story. Quoting: 'After installing the OS onto a PC with an Intel Core 2 Duo E8400 at 3.00 GHz and a hard disk drive, we stop-watched boot-up time at 12 seconds — more than three seconds faster than the previous best time we’ve measured.' It looks as if the switch from GDM to LightDM will have a significant impact as Ubuntu gets closer to 'instant on' status."
I wonder what the boot time would be with SSDs?
does this include the bootloader?
Grub?
Lilo?
How many people actually reboot their Linux systems? I guess if you're on a laptop you might sometimes, but I just use Sleep functionality instead of cycles.
Still, a good (even if by now esoteric) achievement.
...a PC with an Intel Core 2 Duo E8400 at 3.00 GHz and a hard disk drive...
Well, that's a specific Intel CPU, and we know it has an unspecified hard drive.
What actual hardware did they use, so that we can reproduce their results?
Thanks,

I have always been confused when I see ubuntu boot-up times. Does this mean boot to the login screen or boot to a usable desktop via 'autologin'?
When the heck did you start that timer? Bios on many computers takes 5 to 15 seconds. Starting after post I can (and do) boot XP on a 1.6 Ghz single core celeron with 1Gb ram in 20 seconds. By the same yardstick I would hardly call that "instant".

does it take to get flash and java working in the browser on a 64 bit system though?
I will savour the three seconds which I save each half a year.
Also, a 20% decrease might sound like much, but when we're talking about 15 seconds vs. 12 seconds, it's just not something most people will even notice at all.
Those extra three seconds during my monthly reboot are really going to add up!
I used to use autologin until I realized I had to enter my password anyway to unlock the keyring in which the WLAN keys (WEP/WPA) are stored. Is there still a practical benefit to autologin on a laptop?
but unity still sucks
Hibernation?
Provided your hardware is fully supported. A lot of PCs that I've used have no video or no sound after coming out of hibernation. And provided that your hard drive is fast enough to restore the entirety of RAM from the swap file faster than a 12-second boot.
I will savour the three seconds which I save each half a year.
If you reboot only twice a year, how do you remain protected against newly discovered (and fixed) defects in the kernel or other long-running processes?
It's a feature! It's gotta be! Wait, that can't be right...
The more you know, the more you have to say and the more you should listen.
Heck, my computer takes more than 12 seconds to hand over to any OS... I mean, graphics card initialization, POST, initializing 3 RAID controllers.... probably at least 15-20 seconds before the OS gets a chance... I'm pretty sure every modern OS I've tried on my machine can boot to a functional desktop on a fresh install in less time than the BIOS takes...
Why does Ubuntu get all the credit? Isn't this Debian's new system for running init scripts concurrently at work?
I typically don't run the media PC hooked up to my TV unless I'm actually watching a movie or listening to music. Because of a hardware peculiarity, the power button won't put it into standby like my desktop PC. So I just leave it shut off unless I'm using it. It's got 10.04 on it now and boot time is about 30 seconds (never timed it, I usually turn it on and head to he kitchen for a drink). I'd love a fast boot time.

I thought a major advantage of Linux was supposed to be that you only had to boot it once and then it ran forever...
Quidnam Latine loqui modo coepi?
It doesn't matter. You know why? Because I've just updated my Ubuntu to 11.04 (thinking: hey, it's been long enough, they've probably polished out silly issues) and now VLC doesn't work anymore. Google has hundreds of complaints on forums but apparently no one-solution-fits-all answer (extension "XFree86-DRI" missing on display ":0").
As long as developers and packagers can afford to have this kind of fuckups on a regular basis, it will be easier for me to dual-boot win7.
That's about how long it took me with Unity before I gave it the boot too!
Now if only we could control those pesky, random power consumption bugs from the 11.04 kernel.........
I kid I kid. I don't know if that specific issue still affects people because I haven't upgraded, but I plan on installing either 11.10 or 12.04 when they come out.
This is still pretty impressive stuff though, good job Canonical.
E8400 Core 2 Duo is more than a couple of years old. Be interesting to try this on a Sandy Bridge generation Core i7 (and yes, with and SSD)
Should be less than 60% of that time.
Now ubuntu can go from cold boot to crashing apps faster than windows! Ah, bug #1 will be solved any day now.
P.S. Mint has been better since 9.04
"People don't want to learn linux" hasn't been a valid excuse since '03.
I dunno about anyone else, but i've found the last 3 or 4 releases to be increasingly unstable. It's starting to hack me off. White boxes when playing flash, missing window decorations (intermittently), 1px Stay Tray icons... the list goes on. Most annoyingly, I can't even get the native nvidia drivers working. I know i'm not on my own
When are we going to see it used by default on Ubuntu instead of X?
I am glad to see the use of LightDM -- hopefully this reduction of bloat on the desktop will continue. It is not just a matter of boot times but also CPU & RAM usage. This might not seem important of a new top of the range machine, but is great when running on a netbook or a PC that is affordable in the 3rd world.
One of the nice things about Linux was that it was lean & mean, then the desktop guys trashed that reputation.
They are a retarded thing to try and 'show-off'. Who cares that it takes you 12 seconds to start doing something, when the system you load into can't even get past screwing things up release after release. Ubuntu needs to fix it's many recurring, regressions, and add some functionality to other wise lacking programs/code.
I'm always skeptical of these "Boots in N seconds!" claims. Because often it takes another few -minutes- to log in, launch an application, and start doing something useful. We need a new metric. Say, the time it takes from power on to fully loading an uncached copy of example.com in a browser.
I'm looking forward to the first official-status release of Lubuntu as part of the Ubuntu family. I wonder what its boot time will be?
What organization will have the manpower to fork and maintain Ksplice? Writing and thoroughly testing the patches needed for semantic changes to each distribution's kernel takes considerable human effort, as I understand it.
Choose "Ubuntu Classic" from the login screen's bottom-center-right menu for the old program menus. This setting persists.
That's really great. But I hope they remove Unity for 11.10, I've been using Windows until they fix it.
A few minutes? That's the MS Windows (and possibly gnome or KDE) way where you can see the stuff you want to click on but can't touch it beacuse a pile of background tasks are still starting up. Apart from GUI elements (eg. gnome-panel) everything should be up by the time the login prompt is there and with most window managers it's only a second or two from login to usable desktop. It's not all that bad even with the panels but it's still a few seconds that probably could be trimmed off.
My eeepc with the linux xandros interface it came with a few years ago has a desktop ready to use in less than ten seconds from power on if you pick the option to skip the login screen. That is using an SSD though, but it's one that's much slower than the current SSD drives.
Not impressed here. Not even convinced.

Who cares about 12 sec boot time, when the overall experience with the Unity desktop is totally crap.
I wonder how much development time has been wasted saving you 12 seconds per month?
Development time that could have been used fixing Gnome3, PulseAudio, Systemd......

The boot time of my Ubuntu 10.04 on my desktop is 2-3 seconds. True, it's not boot from scratch, it is resume from suspend. But I've wondered: wouldn't it be better to focus on making the OS suspend/resume compatible with the majority of computers instead? I asked myself this because boot time will only be so fast. And for the end user, if you suspend and the machine goes to a no-energy spent mode and he then turns it on and it takes 3 seconds to resume where he left off...it seems better than a 12 second boot.
Did they solve first the hibernation problem with the current Ubuntu ?
or not?
My debian based laptops suspend/resume in less than two seconds. All apps that I need are instantly available and already open in the state I left them. The strain on the battery - when disconnected from power - is minimal (~1mA on this thinkpad). Reboots are for kernel updates. This boot-speed hype is just so 90s.
I did look into bootchart[d] and was able to the get boot-time down to twenty-something seconds IFF I don't start services that I regularly use (e.g. apache2, postgres, mysql, jabberd, yaws, icecast2, tor, etc) and those basically just depend on disk-speed. WTH. If it takes a minute to boot every other fortnight, what do I care.. I spend more times waiting at the coffee-machine or trying to tweak the system.
I've messed around with embedded ARM Linux boards from Technologic Systems. They claim sub-2.0 second boot times on most of their products. However, that's booting to Busybox. Okay, no big deal for an embedded system. But the big time hog is initializing the USB system. If you have devices plugged in on startup, I'm seeing boot times approaching 10 seconds.

I can't to speak to that specific poster, but, in general, the reason people are dumping Ubuntu for Mint or Debian is that Ubuntu is dropping the classic desktop choice in 11.04.
And that fact has been hashed out in almost every Slashdot discussion of Unity, including this one.
