Lubuntu 12.04 is now available

Julien Lavergne has released lubuntu 12.04. Download:

== What is Lubuntu ? ==
Lubuntu is a flavor of Ubuntu based on the Lightweight X11 Desktop Environment (LXDE), as its default GUI.  The goal is to provide a very lightweight distribution, with all the advantages of the Ubuntu world (repositories, support, etc.). Lubuntu is targeted at "normal" PC and laptop users running on low-spec hardware. Such users may not know how to use command line tools, and in most cases they just don't have enough resources for all the bells and whistles of the "full-featured" mainstream distributions.

With many LXDE components, Lubuntu also uses well-known applications, such as Chromium, Openbox, Pidgin, to name a few. The Lubuntu project wiki contains more information on the project and the applications used available.

Unlike Ubuntu, Lubuntu 12.04 is not a LTS, this version will be supported for 18 months. However, a lot of work has been done to improve the stability of the system.

== Features ==
 * Based on the lightweight LXDE desktop environment.
 * Pcmanfm 0.9.10, a fast and lightweight files manager using gio/gvfs.
 * Openbox, the fast and extensible, default windows-manager of LXDE.
 * Lightdm, using the simple GTK greeter
 * Chromium, the open-source version of Google Chrome.
 * ... and, of course, based on Ubuntu 12.04 LTS.

See the complete list of applications on

== Improvements since Lubuntu 11.10 ==
 * A new software-center, optimized to be lightweight, for easy installation and removal of applications from your system.
 * New theme is used, and each previous themes are available in the repositories.
 * Lightdm is used as the display manager with the default gtk greeter.
 * Blueman is now used instead of gnome-bluetooth for managing bluetooth devices.
 * A lot of bug fixes, especially on the panel and the file manager.

== Thanks ==
A big thank to everyone involving in the development of this new great release : LXDE developers, Ubuntu developers, ISO testers, artwork and
design people, social-network & blog writers, support & IRC keepers ... It's another success of a great team work :-)

I am wondering what your complaint is about, as when looking at what Lubuntu LXDE is doing vs the other distros - the technical reasons for LTS are not as important? Q- How important is LTS for a simpler faster distro such as LXDE provides (when it is just a more GUI focused OpenBox, really)? Supporting LTS for 3-5 years does not make "all that much sense" for LXDE distro because not as much is going on compared to KDE or Gnome. With the more "heavy weight distros", where you see huge changes over short periods of time, where those changes for an admin means WORK, a lot of work to keep up if on just an 18 month support cycle (vs LTS that gives you some comfort that upgrading for at least 3-5 years where you will not have to expend a lot of effort to upgrade a lot of system with a large number of GUI changes). Whatever changes you see coming from LXDE will be much smaller, and most likely will be much more comfortable changes that will be far less shocking to the user base (even a commercial user base where training on a new GUI can get expensive). Even when looking at an 18 month support cycle the Lubuntu changes should be almost transparent and easy to admin for...! LXDE is a light GUI that launches applications. The others, like KDE, Gnome, etc are doing a lot more with just the GUI making them more difficult to keep users trained on (meaning more expensive for a business to admin). The apps with Linux, are the apps (KDE or otherwise, and should over time see only the needed changes). Remember, you can run KDE or Gnome apps on the Lubuntu platform (I run both types of apps and like to launch them from Lubuntu better than if I were using then in either KDE or Gnome, etc). I love the fact that Lubuntu's goal - is supporting backports for older CPU designs by keeping the 10.04 release as an even better than LTS release! Again, exactly why, for technical reasons, that you do need an LTS for Lubuntu? Please explain?

Why Lubuntu 12.04 is not LTS like Ubuntu,Kubuntu,Xubuntu,Edubuntu? Lubuntu is not part of Ubuntu team? I am thinking to change for Debian or Mint.See you guys.

As far as I know Ubuntu is canonical and lubuntu is independent, two different things! lubuntu isn't lts because it don't need to be, this DE is not like the others DE cause Gnome Unity KDE are constantly changing, so they can be lts, lubuntu changes are very minimal so no need to be lts, regular cycle of 18 months is better!

Thank you for all your hard work and dedication. I noticed the new theme... I hope it's just a work-in-progress, because 11.10's lubuntu-default (basically just Zukitwo, eh) was much prettier. I guess I just prefer more rectangular curves. Also keeping lxdm because it's much prettier and I already know the config options. Nevertheless, Lubuntu has gotten faster and more stable with each subsequent release on my little Dell Mini 9. PS - I hope you guys put Midori as the default browser sometime. I don't know how much LXDE development has been taken on by Lubuntu team, but if you guys do any work in PCManFM, one thing it's really lacking is a good way to compress/extract archives without using one of the clunky gtk archive managers. I've used squeeze, file-roller, xarchiver... they all don't work so good, and cause the desktop to crash (drops back to lxdm) when dragging and dropping... just generally disappointing. Just a little "Extract..." with a pop up offering "Here / To Folder..." and a "Compress" with a popup asking "To archive.." would be wonderful. Just a few calls to 7z in the background. In fact, if I have time, I will try to modify pcmanfm source code and figure out how to submit it through Launchpad.

Great release, thanks Lubuntu team. Is stable and fast and have nice design, theme etc. Thanks ;)

First of all i want congratulate Lubuntu for beeing such a great distribution, i use it for a long time now. I would like to know why does this one is not LTS... I was really waiting for 12.04 and got disapointed to know its not... I will still use Lubuntu since its my favorite one. Lubuntu FTW. Thank you.

I've been using Lubuntu since 10.04 and was satisfied with 11.10, but after trying 12.04, I've switched to Mint 12 LXDE and won't need Lubuntu again.

SSDs are not hard drives. Even with wearleveling and ECC, they really should be written to not as often as you would to a regular physical hard disk. Some cache, and OS operations would be better if out in RAM, including some functions of the browser too (saved only when powering off). If any Linux distro were for low power systems (using electronic drives) then the install options of the distro should have a path where the install is designed with the goal of extending the life-time of the SSD as well. To date, the newbie, does not have this option, only seasoned Linux users have the ability to customize their Linux distro installs (post install) where the SSD is not hammered with writes that really are not needed to be written to the SSD (RAM would be better for this, and would actually be faster and would use less power if RAM were used). Could Lubuntu have an install option someday where an SSD were the target to install too (one that also then has an install to create a /home partition (that is a better future upgrade or distro switch, or multi-distro booting option to use), without the user having to do them themselves (again a more advanced Linux exercise).

I'm thinking about doing the same. I had Lubuntu 10.04 and 11.04 - both of which were really good. Since Lubuntu became part of the 'official' Lubuntu 'brand', it has gone totally downhill. It got rid ot aMSN, and I cannot install aMSN now because it lacks a vital dependency; it has KMess which is at best unreliable and at worst just plain bloody rubbish. Lubuntu 12.04 hasn't made my computer simpler: it's making it unusable. I had Linux Mint LXDE before and I'll be going back to LXDE Mint or going on to a better, more user-friendly system such as SolusOS Eveline RC4. You guys have totally lost the plot. And you've lost me.

Windows boots slower every new release. Having options in the Linux world gives computer users options vs using just Windows. It is good that there is a distro supporting older CPUs (that is also an accepted member of the Ubuntu family). Lubuntu (LXDE) is very good to use for all older computers, and for use as the GUI for all LTSP (Linux Terminal Server Project) education servers as well (lighter weight and faster , using less RAM, easy to set up panel, etc, all that is good - when you are trying to add as many users as is possible on one server). We all know that Windows is getting heavier and heavier in the minimum hardware requirements area, that KDE is not the lightest weight, and that LXDE (or OpenBox) is the answer to making all systems run wicked fast. When you add an SSD to the drives of these older systems, or LTSP servers, with Lubuntu, then the systems become so quick, that they are fun to use and boot very quickly. After playing with the GUI for a while it does not mean much to have a complicated one, as all you want to do is get to the application that you want to run (and Lubuntu does that). I tested Android OS on an Archos device where it came with 3.2, and it was ok, but could have been quicker, then when upgraded to Ice Creme Sandwich, it got a lot slower (obviously ICS uses more resources than 3.2). Why not use Lubuntu on such devices instead... Lubuntu just is quick period. We don't need Android, or any other fancy power hungry GUI on mobile devices. Lubuntu would be perfect for them too. Additional hardware resources use more power generally - someone someday will build a low power netbook or tablet (maybe running AA or common off the shelf standardized battery so as to make the device last 10 - 15 years with the consumer presented with the option/ability to easily find and replace a standard battery over that time, that could be bought from an end cap at any food, hardware, or electronics store), where said device, will run all day or longer on a charge (might need Pixel Qi screen too, for direct sunlight uses, and low power ability of that screen by design that OLPC gave birth to -!video_idea_id=13336 ). This design, could then work it's way onto corporate desktops where the AA battery backup in the device, replaces other power backup schemes, and the whole network of computers could be run from solar panels on the roof (even the servers, if the servers were built with power savings in mind too). Linux can be set up to turn off CPU whenever the system is not doing much, like when you are typing a note, or doing most anything on just the screen (then the CPU turns on only when you need it to turn on). Lubuntu, would be the ideal OS for such low power, low resource, energy saving "green" systems (both mobile, and desktop). Lubuntu is the ideal platform to be optimized to be the most green OS to run on systems designed from the ground up for energy savings.

Hello! Yes, I'd LOVE to see Lubuntu on an Android tablet. Bring it on!

I'm trying out Xubuntu 12.04 as an alternative to Windows, but i encountered problems with USB Broadband connection that keeps getting disconnected and its hard to find a fix to disable Xubuntu's "USB autosuspend" feature. Will i face this same problem with Lubuntu 12.04? Another thing is the absence of multimedia plugins such as flash and mp3 codec in Xubuntu which is making me take a look at Lubuntu or Mint. I'd appreciate your advice and help on this. Thank you

We have been testing the Norhtec Edubook (uses AA batteries in this small netbook). The Edubook with the XCore86, uses the same design of their other products (Surfboard, etc). And since the Edubook (that boots Windows XP fine, but slow, so that is why Lubuntu might be perfect for this device) uses the 586 design (on a new chip, where their newest version of the XCore86 is faster with 1GB RAM), ... anyway, we found that we could not boot Lubuntu 12.04 at all on this older CPU design (again, an old design, that is being built new today in this system on a chip design). After looking around on the Lubuntu site, we found that the i586 is only supported via the 10..04 Lubuntu and that backports are maintained by the Lubuntu team? That 10.04 Lubuntu boots fine, but does not see their networking, etc. Do you ever accept hardware drivers to be used with your efforts to maintain that 10.04 version (so that Lubuntu "out of the box" could maybe be used to "just work" from your Lubuntu 10.04 .iso file? If so, then what would need to be done to get support for the Edubook and Surfboard into the Lubuntu .iso file.

Thank you guys for all your hard work. Lubuntu is a pleasure to use!

Hello, I switched to Lubuntu, because I wanted to have a light desktop, with no graphical "garbage". I work at and with the computer and don't need such an overload. So I was glad and happy with Lubuntu, but now I am asking myself, what goes wrong? My Lubuntu 11.10 tells me a new version of Ubuntu 12.04 LTS is available? And asks me whether I want to upgrade? Is that a wrong upgrade notice? And how can i upgrade to 12.04? Pls don't tell me I've to install 12.04 from a CD or DVD! I searched for that topic in the wiki, but didn't find any hint. Thks in advance for your help Ulf

Hey! I have recently switched to Lubuntu as well and ran into the same issue as you did. I did some googling and this is what i found: apparently, it is only a wrong distro name so your upgrade should be not problematic any more.

I've had the update manager pop up with a message asking me to upgrade to UBUNTU 12.04 (which isn't Lubuntu) on looking into this through google, I find there is a lubuntu 12.04, so I start the upgrade. The upgrade manager tells me I need about 880 megs of downloads?! I'm on a borrowed WIFI connection, I can't be downloading almost a gig of data! Is there a new 12.04 cd image? what's the difference? Why would an update, upgrade take so much more download to get into my computer than downloading a whole ISO? Shouldn't there be some things left alone that don't need to be re-downloaded for an upgrade? Shouldn't this mean, theoretically that the download for upgrade through the manager is only a part of the download for the whole distro, and thus much smaller? Yes, I installed a new chromium, and that will be updated too... But I see chromium is the new default browser anyway, if I was to just download a new iso to install that way. Wouldn't it be good advice to let people know that the upgrade is better through a complete install disk, (which I can get from another location) rather than the update manager... -how about making a new cd install disk have the ability to properly upgrade an existing install without wiping the system...

Well, it is quite difficult to understand that a derivative made for making reuse of old PCs user friendly... still compel them to upgrade every year or so! Better install good old windows XP: It's eleven years old but, supported until 04/2014, still more hassle free than a brand new Lubuntu? Well, Lubuntu may not have a team that size close to Ubuntu base, but if you have to focus on something, please focus on LTS: For a distribution that targets old hardware, that make even more sense (few drivers for brand new hardware to bakport) than for Ubuntu... and having to upgrade so much is a concern for users. Look distribs that target corporate environments: RHEL and so on... and their support time! Don't expect casual users to do what sysadmins don't want: Upgrade so often!

I really like Lubuntu; I am using Lubuntu 11.10 in a Laptop, but I see the bigger problems with the distribution have not been solved in 12.04, so there is not enough incentive to upgrade. - Suspend mode does not work. You choose "suspend", and then you cannot wake up the computer again ... or apparently it wakes up, but you see the screen black no matter what you do. Hibernate does not work, but this is actually is a problem with all Ubuntu distributions. - Battery life is not optimized. Allegedly, this distribution is "less resource hungry and more energy-efficient", but actually battery life is worse than the main distribution of Ubuntu with Unity!!! My CPU was having a very high temperature and I tried all the tips in the Ubuntu forums, but nothing worked until I installed Jupiter and choose the "performance on demand" mode of this program. I hope Lubuntu developers could pay attention to these problems. Perhaps, they could develop LXDE based software for power management to avoid gnome or xfce dependencies on this matter :)

These kind of issues might depend on a lot of factors as well as on the hardware you use. I suggest you join the lubuntu mailing list to discuss it in detail:

Hello! I just bought a Netgear WNA100 USB Wireless-N dongle. I just wanted to congratulate you folks for getting Linux to the point where someome like me can just plug a wireless adapter like that, and have it to install without a hitch. THAT'S what I EXPECT from an OS! And now, a question: How do I restore the themes and look included in Lubuntu 11.10 to 12.04? I like THEM *BETTER*... Your help would be deeply appreciated. 73 DE N4RPS Rob

I have tested and liked Lubuntu, mainly because what it means in terms of packages, stability, etc., to be a Debian/Ubuntu derivative. For netbooks and older hardware, is also recommendable. I think to be a LTS is good, since upgrades are much less complicated. It not uncommon to damage the system when doing dist-upgrade, and the user ends up doing a full re-installation of the system, what is painful for anyone. In this sense, I'll keep advising Lubuntu to become LTS, accompanying Ubuntu's releases.

Im looking forward to recieving a copy of this from a friend soon. Looks perfect for my old PC so i can finally ditch windows XP. Looks neat and tidy and very responsive my only quarm is that its my first ubuntu based OS so may take a bit of adapting but il pick it up quickly. Thanks guys.

I have had trouble using Flash or Shockwave plugins on the Chromium browser on this new addition of Lubuntu. I realize that Adobe is phasing out support for Linxu. However, Gnash and Lightspark do not seem to work with anything aside from YouTube videos. Even if the plugins are reinstalled, the Chromium broswer either crashes or does not recognize them. Is a fix coming?

Un grazie a Lubuteam per il lavoro svolto. By Fabio Triestino user

I love Lubuntu. For so long I was told how less bloated Debian, the "Universal Operating System", is compared to the 'buntu's", but compared to Lubuntu, Debian is slower and boots slower. I used to want Debian but after so many problems with wireless I have to ask, "Why?" especially since Lubuntu is so fast and works. "Wireless & Wine" - the two reasons I reject the "Universal Operating System" It doesn't matter if I have all the non-free firmware installed, or if I can see my networks, the "Universal Operating System" would always pop up an excuse for why I can't connect, "bad password" "bad this" "bad that" when it wasn't even true. The Wine package has been layed to rest. The "Universal Operating System" won't touch it. Lubuntu allows me to tweak what I want to tweak. Unlike the "Universal Operating System", I don't have to tweak it to get it to perform its most basic functions.

There is not much differences between lubuntu and ubuntu. I do not know much abut lubuntu but I wanna use this.

Pcmanfm wants to show me two instances of a removable usb in the lft pain. It mounts the usb automatically. That makes it stranger in that I have deliberately set the preferences to not automount anything. I am going to replace gnome-disks with palimsest and see if that helps, though I don't know why it would. If that doesn't work I'll try replacing pcmanfm with thunar. If that doesn't work I'm going to have to go back to that bloated xfce version of Mint Debian.

I do not know much about lubuntu. I feel interested about this. Where I can get more about this?event marketing service

I used Windows XP on my old laptop and it gives me a long hang everytime I reboot. When I switched to ubuntu, this changed, but still hangs when flash is playing. Now, lubuntu is what I am using. So fast, so stable, so clean, so easy to use, so light. The five "so's " just stop me from using other OS.

Let me try to clear up some evident confusion by telling you how I see things (may be wrong, but not by much): LXDE is a Desktop Environment, it is not a Linux distro but sits on top of a distro - e.g. - Ubuntu to provide you with a simple, clean, light and fast user interface. Without something like it, we would all have to use the Command Line Interface, rather like the long-forgotten MS-DOS before Windows took over. Obviously LXDE has to have the right hooks to steer the underlying distro, but the heavy development work gets done by the distro developers. Consequently if you have LXDE running on top of Ubuntu 12.04 LTS, the main burden of providing that Long Term Support falls on the Ubuntu developers. Far fewer changes should be needed for the corresponding LXDE. Lubuntu is just a marriage of convenience with LXDE adapted to live with Ubuntu. I installed Edubuntu 12.04 (a version of Ubuntu 12.04 LTS with a large amount of education-support packages) but didn't like the Unity desktop environment so went - in Edubuntu -to the software repositories and downloaded and installed the appropriate version of LXDE, making it my default desktop environment. Thus, if you like, I created my own EduLubuntu 12.04. Fabulous, Fast, Frill-free! And I expect that that LXDE will, as a package on the 12.04 repository, be updated as needs may be under the LTS provisions of Ubuntu 12.04. Don't hassle about the absence of the LTS designation on Lubuntu, is my personal opinion. You should continue to get most if not all of the LTS benefits via Ubuntu 12.04. LXDE rocks! LXDE turns a rock (Ubuntu) into a rocket (Lubuntu)... Make no mistake, it's great having the rock-like benefits of Ubuntu LTS (including the enormous software repositories). Lubuntu is a way to access these benefits without carrying some of the overheads.

I run an Ubuntu laptop already and am now looking to change my desktop over after playing with Win 8..... just finished creating my install disk and will head home to start the process.Thanks for your hard work, looking forward to playing with it (will be 'upgrading' to Ubuntu after...its a long story and don't want to bore you all with it just yet LOL... Once again a big THANKS! :)
