Ubuntu Heads To Smartphones, and Tablets
First time accepted submitter GuerillaRadio writes "Mark Shuttleworth is to announce that Canonical will be taking Ubuntu Linux to smartphones, tablets, and smart TVs at the Ubuntu Developer Summit in Orlando, FL starting today. Shuttleworth said, 'This is a natural expansion of our idea as Ubuntu as Linux for human beings. As people have moved from desktop to new form factors for computing, it's important for us to reach out to our community on these platforms. So, we'll embrace the challenge of how to use Ubuntu on smartphones, tablets and smart-screens.'"
Having a tablet oriented linux distro is going to open up the linux market. Ubuntu has a reputation for working out of the box, let's see if they can keep it with such unusual hardware.

No we know why Unity looks the way it does.
to other platforms. Good.
Finally, a use for Unity!
Perhaps they should also try a system for Desktops where the system is usable with a keyboard too? :-)
In all seriousness, this sounds quite interesting and hopefully will help shove down the prices of hardware. Not sure how it would, but here's hoping!
...since Unity has made Ubuntu completely suck on anything with a mouse and keyboard.
Google has taken Linus and modified it to suit their aims and goals, rather than using the power of community Linux. Canonical will give the smartphone world the power of Linux minus the controls and restrictions imposed by Google. Customers will be the biggest winners here.
If you keep throwing chairs, one day you'll break windows....
Microsoft doesn't have a monopoly there. That's the big difference. They're competing mainly with Apple/Google, and I think they can take them on.
To offset political mods, replace Flamebait with Insightful.
If he is going to announce it, but the news is already out beforehand, then....isn't it already announced? What's the point of the Orlando, FL presentation now?
They modified Linus? What did they do to him? I bet he's pretty angry about that!
*Looks at Unity*
Well, maybe not that shocked...
Live today, because you never know what tomorrow brings
Customers will be the winners? Customers won't know.
Unity on cell phones or tablets won't be seen by more than a handful of nerd types. The general public will have *no idea whatsoever* that it even exists.
Possible, but also consider that the handset manufacturers are the ones imposing most of those controls and restrictions. They benefit from the ability to bundle un-uninstallable sponsored apps (including spyware) and can more easily ensure obsolescence and thus future handset sales if they have means to prevent software upgrades. Even if they did use ubuntu, they would probably have to find some means to lock it down. Maybe they'll use a bootloader that only loads signed OS images. They certainly won't be letting the user have root access - that would be a technical support nightmare. Even Android doesn't do that.
Don't worry, it wasn't the real Linus, they forked him first.
Guns don't kill people! Admins do!
I'm holding my breath for a manufacturer to ship a phone with ubuntu on it.
[gasping] OK... now I'm not.
Interesting- but for the near future at least, I can't see phone manufacturers shipping phones with Ubuntu on them- If you want Ubuntu on your phone you'll need to remove an existing operating system.
How many people will actually remove iOS or Android to get Ubuntu?
Can you dual boot a phone?
"That's the way to do it" - Punch
I bet the two people that weren't expecting this are totally freaking out! Seriously though, let's all hope it stays there. The idea of a "unified experience" between two fundamentally different control schemes/types of computing is silly and prone to eventually pissing one side off, and Unity has drove this point home quite perfectly.
As long as it's simple to install on a variety of easy-to-obtain unlocked smartphones, I'll be happy. The whole reason I don't have a smartphone yet is because I'm nervous about entering anyone's walled garden. This has been a long time coming, and I'm thrilled that it's finally here.
Happy
Canonical previously announced that their distro was being preloaded on three ASUS netbooks. That was in August. Didn't happen.
Canonical issued that Linux press release, but Asus never said they were going to ship those machines with Linux. Canonical has no credibility.
As long as they avoid the Android style fragmentation / lack of support for the older phones I'm waiting for more news on this!
GENERATION 27: The first time you see this, copy it into your sig on any forum and add 1 to the generation.
Good news? You must be joking!
This is blinging
Canonical will give the Linux smartphone world further fragmentation.
With Android and iOS going strong and new MS and Blackberry upcoming, will there be enough incentive for developers to support yet another new mobile platform? Well, unless supporting is made as easy as minor changes to build process and codebase.
The whole reason I don't have a smartphone yet is because I'm nervous about entering anyone's walled garden.
U.S. carriers are still in control of the U.S. cell phone market, and Ubuntu won't help you break that. First, any phone that comes with Ubuntu isn't going to be available on subsidy from a U.S. carrier. And if you don't take a subsidized phone, carriers will still build the subsidy into the monthly bill as if you had taken a subsidized phone. Second, even Ubuntu on a smartphone won't help you work around U.S. carriers' policy of charging you extra if you try to "tether" (use a phone as a proxy for your laptop so that you can use up the rest of your data plan's allocated megabytes), and it doesn't magically get U.S. carriers to start offering low-minute smartphone plans (still have to pay $39.99 per month for 450 minutes per month, even if you'll probably never use even 60).
(Not in the U.S.? If not, sorry.)
Ubuntu's traditional market niche is the technical and professional market, people who used to use UNIX workstations. Unfortunately, with 11.10 and the upcoming move away from X11, Ubuntu is hell-bent on leaving that market: Unity is already nearly useless for power users (it doesn't work well at all on large or multi-screen setups), tools like Synaptic are becoming non-standard, etc.
Unfortunately, Ubuntu doesn't have a chance in the tablet and smartphone market either. That market is already well service by Android and iOS. Ubuntu has virtually no mobile developers. And if it manages against all odds to even get a small market share, Ubuntu will face the kind of patent feeding frenzy that Android is being subjected to.
Too bad Shuttleworth couldn't leave good enough alone. He's going to kill Ubuntu and seriously hurt Linux as a whole.
Interesting, Debian derivatives have been running on mobile devices for years (Maemo on Nokia devices and various distros on OpenMoko devices).
Debian is finally getting into the mobile game too, I guess Unity will become one of the mobile UIs added to Debian:
http://lists.debian.org/debian-devel/2011/09/msg00126.html
http://bugs.debian.org/643678
I guess KDE's Plasma Active will be in there too.
Ubuntu making deals with OEMs will hopefully mean more open drivers, making it easier for folks to use Debian on mobile devices.
They fucked up the desktop with Unity, now it's time to see what they can do with smartphones and tablets.
The future of computing is TABLET PCs. Having a touch screen tablet that can flip out a keyboard to become a laptop will become the most popular thing once they are marketed right. People buying ipads today are simply wasting their money.
Ubuntu needs to keep both the Gnome and Unity desktop. Unity is awesome during TABLET mode, but I much prefer Gnome during my LAPTOP mode.

LibreLinus?
Hmm....where have I heard that name before? OH! They're that company that seemed to have a pretty stellar Linux distro based around the Gnome desktop, but for whatever reason the founder of the company decided it was HIS distro and so he didn't have to listen to the people using HIS distro and only HE could design THE ONE TRUE DESKTOP (TM)...
Lost a lot of users after that. Funny thing, never saw a company quite that intent on pissing off all their users until they leave...
Have a Virgin Mobile USA smartphone? Give VMRoms.com a try!
Yeah they forked him HARD!!!! ;-)
I guess "fragmentation" is a synonym for "competition." If you want the best stuff to exist (heh, but with everyone disagreeing about what is best), then you're in favor of it. If you want the world to unify to support something that maybe isn't as good, you're against it. I guess it all depends on what you want.
Yes, you can make a case for unity. People have been preaching that for (literally!) thousands of years. And yet, not everyone is sold on the idea.

... I have to remember that I'm not really a customer -- only a subscriber. The telcos are the actual customers in this equation, and so far they've not taken a liking to operating systems that are too open (think Openmoko and Maemo/Moblin/MeeGo). So, although I wish Mark all the luck in the world with his new strategy, I suspect the odds are stacked against him regarding the phones.
modprobe -r anger
problem solved
then I don't think Canonical will provide any significant competition any time soon. I've used their preinstalled images on my decently powered Pandaboard and the performance just blows. Best of luck though, it'd be really nice to have a portable device with a touchscreen AND ssh enabled right out of the box.
He never asked for this.
Yeah, because Canonical strayed oh so far from GNOME... Have you seen GNOME 3? It looks like Unity.
What was that? You can still use GNOME anyway (or KDE, XFCE, Enlightenment, or whatever else floats your boat)?
Are you aware that GNOME's website is hosted by Canonical?
now they are trying to put Unity on my phone and t.v.? no just no.
So we can look forward to the "year of Linux on the Tablet" just after the "year of Linux on the Desktop"?
What's great about open source is choice. Users can have as much source code as they want, and in as many versions as they want. There are apps to do everything. With just a little more tweaking, everything can work.
Several versions of xBSD, each in several distros. Dozens of distros of Linux, each with several versions. And millions of apps, which will work on one of these OS's.
It's very similar to politics. There are two big main choices which are for rent for a time, and will do a few jobs, or favors. Outside those, there's millions of options.
chroot Debian on my Android was never satisfactory. I want a standard Linux phone, ideally Debian based. Yes I know, the N900, but it is too old and a dead end. I'm no fan of Unity and modern Ubuntu, but maybe on a phone, it'll win me over. Very interesting. Also, more competition is always good. :-)
If simply existing in the same market would mean "competition", then desktop linux would skyrocket the innovation - after all, there are so many competing distros! Instead, it's mostly about Ubuntu, with Fedora and Debian getting a bit of attention now and then.
To compete, you need to attract the user with something others don't have - in desktop Ubuntu's case it's "being free and open, most newbie-friendly among Linuxes and caring for design" (with latter a bit controversial lately), but what can they bring to the mobile?
Only few will care for openness, as long as a) Angry Birds are available in the app store/market, b) changing mobile OS doesn't become as simple as changing desktop OS.
Design and noob friendliness is already there in competing platforms.
What can be there in mobile Ubuntu for Joe Average Consumer/Joe Average Developer?
After looking at Gnome3 with the 11.10 upgrade, I was really taken aback. Even after loading in the "revert to classic" add-on for Gnome3, it didn't feel the same as what I had been using. I prefer a nice, clean, and quick desktop. I tried Kubuntu but found it to laggy, I did settle on Mint running XFCE. Very clean and quick interface. I like it as a Ubuntu replacement for now.
I really don't understand why people are including negative comments towards Ubuntu all the time - like "spreading the pain" and "Unity sucks." I personally have moved on to other more stable distros like CentOS and Slackware. I'll admit Unity isn't my favorite, but Ubuntu is still open source and free - so stop complaining about it. If people are so uneasy about the direction of Canonical, switch to a different distro or fork it and do something about it.
To me, Linux is so great because of its diverse nature. Voicing negative comments without ideas for a "better direction" just get in the way of the evolutionary process. Ubuntu is just one unique way Linux can evolve. It's an extreme difference from some distros but it's interesting to watch.
... is PulseAudio. It's craptastically cumbersome and buggy on the desktop, and would be a downright nightmare to troubleshoot on a phone.
On a related note, it's interesting that Canonical is thinking of putting Ubuntu on mobile devices now that it's grown so bloated on the desktop. So many Gnome and other bundled apps that we never use, etc. I still think that Ubuntu is the best desktop Linux available today, but it needs to grow slimmer versus fatter.
On my Asus Pad Transformer I change root to debian. I mostly do stuff in the terminal. But from time to time I start an vncserver and use an android vnc client to connect to that. Then I have a complete X session, I use xfce4, but I could use every other wm. There is a project on github to implement an xserver on android (see android-xserver).
The question might be why? Well it's pretty simple content creation! Android is great on the tablet when just using it to play media, browse the net or read a pdf. But when I want to do some real stuff, say write a paper, create a demo or even write a program, you want all the tools that linux has[*]. Debian has them, ubuntu has them, other distro's have them. So it is a great mix, android and some linux distro on the side.
Why don't they create one good app that automates everything. They could put it in the market, call it ubuntu, and make it so that the first time a user starts it, it creates the changeroot and the next time the user starts it, it logs in. Only problem is the root requirement. But if they are working with the OEM, they could rock!
[*] next to linux, you also want the keyboard dock that is available with the transformer!
Great News. Tablets are the future & Glad to see Ubuntu there.
I would say this. Fix the f...rikin bugs first! Ubuntu and pretty much every Linux distribution for desktop simply... sucks. And guess what? It's not going away. It's a soup of buggy software.
I ended up installing them after the recent upgrade. They provide a simple adjustable GUI similar to the 'ubuntu classic' but with the OS tie ins that the straight gnome packages don't provide. Making a user go through crap like that just to get to something that isn't painful to use is the kind of thing I used to praise Ubuntu for not doing. I commend them for putting together a tablet interface - good forward thinking. Forcing it on the PC is unnecessary and smacks of the kind of hardline control that irritates me about apple products. I've spent years with Ubuntu now and I thought my days of distro hopping were over - now I'm not sure. Thanks for alienating me Ubuntu - job well done.
Lost a lot of users after that.[citation needed]
I've only seen arseholes like you complain without mentioning anything. Look, you don't like Unity, good. But you're the one hurting Linux on the desktop. If you give a non-Linux user a chance to try it out (without saying anything, he will probably like it. So stfu and do something instead of complaining.
Safe prediction, based entirely on past performance. It. Will. Never. Happen.
Canonical can't even give linux away to "the world" after 7 years of trying. Hint - Apple sold more than 20 million iPhones and 9 million iPads in the second quarter - that's way more than the total Ubuntu userbase world-wide after 7 years.
And Samsung is now cleaning Apple's clock.
Neither of the market leaders is going to worry about Ubuntu - it has a long history of big announcements that go nowhere.
They effectively lost the desktop market with Unity.
Do you hate Unity? Then use Kubuntu and be done with it. Works well.
Also, stay with the latest LTS (10.04 at present), and you don't have to upgrade for 3 years. Less headache.

Linux has ousted home grown os's in the embedded market, dumbphones, tv's, thermostats, cars, toys, gps's, etc.
android/Linux is is the process of of displacing or at least co-dominating with apple in the smartphone-tablet world.
i know it isn't a consumer market but it has nearly completely dominated the it world, nearly killing commercial Unix's, bsds, openvms etc. and it rules the cloud, both as and/or part of the host, and as the guest system (Linux+xen, Linux+kvm, Vmware[as the boot-loader and controller for the vmware kernel.], oracle unbreakable Linux+oracle cloud, and amazon e2 cloud is rum on Linux with many of the guest OS being Linux.
really the only place it hasn't dominated is in the fat client home and business desktop. So i wouldn't count ubuntu out yet.
---Saying gnome 3 is better than windows 8 not so much a compliment as it is damning with light praise.
If Ubunghole wanted to get on the smartphone and tablet bandwagon, they should have moved in that direction YEARS ago. Instead they kept focusing on "Maybe THIS will be teh year of teh lunix on teh desktop!!!"
Is this Ubunghole FINALLY admitting teh Lunix will never, ever beat Windows? But now, by the time Ubunghole Moble (or whatever they'll call it) gets ready for market, it's going to be competing in a VERY crowded field... and now, against Microsoft's always-superior software. And an even bigger threat will be Apple's strategy to win in the courts rather than the marketplace: there isn't much money to defend free software from a lawsuit, especially seeing how 99.999% of all Lunix "innovations" are "borrowed" from other sources.
I read a lot of critizism against Ubuntu for taking this route, but I think that it is necessary if Ubuntu is going to keep up with the hardware and not fall behind.
Face it. Practically no hardware vendor builds end-user hardware specifically to run Ubuntu. Most PCs that run Ubuntu now were designed to run Microsoft Windows, and that is how it is going to be for a considerable time. ... Towards touch-based devices. At Microsoft's "Build" developer conference last month, they even referred to tablets as "tablet PCs".
And what is the future direction of Microsoft Windows?
It isn't just tablets. Microsoft is pushing hardware vendors to make all screens touch screens: even 24" desktop screens.
In the future, people are not going to be as willing to switch from Windows to Ubuntu if it means that they are going to loose that much capability.
Personally. I would really like a tablet that runs a real Linux distro, is fast and has a high resolution IPS screen. I have been dreaming and yearning for one for fifteen years now, albeit I envisioned it with a stylus.
But fuck Unity! I still run Ubuntu 10.04 LTS (with Gnome and Window Maker) so that I would not have to stand for that crap, and that is what I installed on my newly purchased netbook also.
"We mustn't be caught by surprise by our own advancing technology" -- Aldous Huxley
Shuttleworth has not only disregarded the community's complaints about Unity, but now his blog is actively deleting and censoring any further criticism. Pleas for them to offer a desktop that actually looks and works like a desktop, if not as a replacement for Unity then at least an offering with an equal amount of support, are being treated with a "we know best, go away you silly peon" response. Sorry Mark, you are not Steve Jobs, you can't get away with that routine. Unity is a disaster, and when you have Linux luminaries like Linus Torvalds and Eric Raymond switching their desktops to Xfce, you know you're heading in the wrong direction.
I myself have also made the switch to Xfce, and after doing so, and even after having been a loyal Ubuntu user for five years, I'm wondering what's the point of staying with Ubuntu at all if not for what used to be a gorgeous desktop. I did a little research and found that aside from the formerly gorgeous desktop, all of the things that I loved about Ubuntu were actually things about Debian. Now that Unity has replaced the good desktop, the only advantage Ubuntu has over Debian is a better installer.
Yes, Unity will probably be more at home on a device that has no keyboard and mouse, such as smartphones and tablets. But competing with Android (not to mention Apple) is going to be a tough sell there. So why are they blowing it all by alienating their existing installed base?
Tired of FB/Google censorship? Visit UNCENSORED!
I wish them best of luck. I played around with various linux distrs on my openmoko phone. Those are supported by the community and still require a lot of work. However ubuntu phone will be fun.
Lost a lot of users after that. Funny thing, never saw a company quite that intent on pissing off all their users until they leave...
Except maybe Netflix.
...Netflix...?
Was it good for him?
FATAL: module anger is in use
Google has taken Linus and modified it to suit their aims and goals, rather than using the power of community Linux. Canonical will give the smartphone world the power of Linux minus the controls and restrictions imposed by Google. Customers will be the biggest winners here.
Google tried to use the power of the community, but was shut down by a bunch of morons that didn't understand the reality of the problems Google was trying to solve. They then proposed a bunch of "alternatives" and claimed to have fixed the problem without actually addressing squat. As a result, there is now an entirely unused power management system that nobody wants. Linus recently admitted the community screwed up handling that, and should just take Google's patches and then try to improve the code if need be, since Android is shipping and not taking the code isn't causing Google to lose any sleep.
I assume you're referring to wake locks, anyway, as that's largely the only thing Google hasn't upstreamed back to the Linux kernel.
While I'm all for an open-source Linux-based OS on handheld devices, the fact remains that it's not exactly the most battery and CPU-efficient operating system. When you start putting virtual machines and high-level languages on these devices to run cross-architecture applications, you only further diminish the device's capabilities. This has become commonplace now, focusing on ease of development over efficiency, and it's really rather disappointing considering the raw power available in these kinds of devices.
What needs to happen for phones, handhelds, and tablets is what happened with PCs: a single open architecture which allows anyone to develop software that will run on any other manufacturer's device. And the obvious choice is basing it around ARM. Then you develop the operating system to run solely and efficiently on that platform. At that point, applications can be developed in native code, and interface with the hardware through an API, which can then use drivers to deal with different types of hardware in the device (from display to wifi and whatever else).
Unless that ever happens, we're just going to continue to stifle the potential of devices, wasting so much battery power in the process, with companies focusing on throwing more hardware specs at it rather than fixing the core issue. Putting Ubuntu on handhelds doesn't fix any of this. In fact, considering how it's already layer after layer of code even on the desktop edition, it's only going to make the problem worse.
There is absolutely no excuse for a 500+mhz device to ever run sluggishly when attempting the same basic tasks that still run fine on aging desktop computers.
I bet that made him REALLY angry. Was he done yet?
This article should have read "Mark Shuttleworth continues his campaign to clone Apple products as closely as possible."
Sorry, but am I the only one who doesn't think we need another OSX-like operating system on a tablet? Ubuntu is ruining what Linux worked towards for years by trying to lure in users with pretty colors and big icons. That's not what Linux is about. We're not Apple users. We don't care about that shit. We want a system that works, and works efficiently. Cloning OSX is counter-productive to that goal, since it's certainly not the most productive operating system out there.
The dock is one of the worst task-management devices ever conceived. You have no information about how many windows of a particular application are open, nor what those individual windows are displaying. The single file menu bar along the top is an inefficient window design forcing you to completely switch windows before you can access the menu for a different application. A large icon-based application launcher results in more scrolling and digging for what you want to run as opposed to a basic cascading menu of categories. Window controls at the top left, and dialog buttons with the most important button on the right, are completely counter-intuitive to how people read and process information.
The entire design is taking us back 30 years to when the Mac OS first launched, when computers were hardly capable of running more than one application at a time. Microsoft nailed it and created the most productive desktop OS interface with Windows 95 onward. Apple, on the other hand, remained stagnant and has never changed its interface other than adding a dock. So why the heck is Shuttleworth trying to copy it? Ubuntu created a huge userbase, and finally gave Linux a single platform to rally around and focus development in a single direction, but now they're trying to shove a poorly developed interface onto everyone in the name of "innovation."
Yes I know you can simply switch back to Classic, but that doesn't automatically fix the other initial problems of backwards window controls or dialog buttons. It also doesn't change the fact that that's not what people are going to see and use by default. And the default is, quite frankly, a mess. Let's not teach people to use computers like this, before people start getting used to it.
And the reason why it will never work will be the absolute inability of open source developers to A) agree on a standard for gestures and B) actually adhere to the standard. Everybody will think they have some critically important reason why they can't use the same gestures everyone else is using, nobody will be able to figure out how to use the applications, and the whole thing will look like an amateurish piece of shit. Just my prediction.
Htc hd2 runs ubuntu natively quite well, and can dualboot android, windows mobile, windows phone 7 and meego...
Ubuntu is not bad on the phone but its no replacement for android, I look forward to seeing what they do with the ui and it will be good competition for android :)
Check out xda-developers
Actually I heard they really did a "git branch".
One of the best selling points of unix is the philosophy of doing one thing and doing it right. They should relentlessly focus on the desk top market until they have at least %80 before thinking of anything else. Then if they do target new markets use a new product like android. So depressing to see these kind of dumb moves from the only half way decent linux desktop.
So, once they have ubuntu for smartphones half the posts on the Ubuntu forums will be "My wifi don't work" and the other half will be "My phone's battery only lasts 29 minutes."
if your life is such a big joke then why should I care?

I'm in the mood for streaming some Netflix on my Ubuntu machine. Oh, wait, I can't.
And then to stop the fracturing of the operating system, Canonical will hold back release of source code...
Don't forget about the new users lounge, where the most active topic is "I chmod 777 my home directory and now I can't unlock my phone. Even when it's ringing..."
Ubuntu Jihad Hacka! It is all eye need...
Even better (IMHO).
Sharp released a small Ubuntu based tablet called the Netwalker years ago - I own both the tablet and pocket computer versions. They are both pocket sized, so not exactly comparable with "tablets" like the iPad. There are some input issues on the tablet because the input software (made by Motorola) is buggy but other than that I get significantly more functionality out of it than I do my Android phone - simply because it runs a lot of software that "should" only be on the desktop and it runs it just fine - and it's easy to just apt-get install whatever rather than digging through the market. On top of that I can compile whatever I want and run it right there, I don't need to statically package things in a big blob and export them.
Of course anyone who just read that and though "wow, that IS great!" should take a step back and realize the general tablet market doesn't do any of that.
Funny thing, this sounds a lot like Mozilla, too. What a shame.
10 inches is way too small for full penetration into the market (no innuendo). Agreed, the weight and pricing is not ideal at the moment, but in time, I think that will improve. Once they make a thin, light weight version of, say, the Dell XT3, with a screen large enough to display a full A4 sheet of paper, I'm certain you'll see these devices as the main product in any store.
When Ubuntu 11.4 arrived I quickly decided to fall back to the Gnome "classic" GUI. But I decided to give Unity a new try after the update to 11.10. And it is still there. I actually like it. I have a 21" wide screen and, like many developers, have a huge amount of windows open at all times. The new Unity handles it at least as good as the Cairo dock I was using until now. I recommend skeptics to give it a try (again). Take 20 minutes to explore the features. I think Canonical's main error was releasing Unity too quickly.
again, canonical is comical
