I just bought this little Win10 underpowered (but ruggedized) laptop. I am going to put Lubuntu on it and I bet it'll run like a scalded ape.

Lubuntu is really wonderfull. it works really fast and i can modificate LXDE simply

Followed the instructions on for the minimal install. Installed Ubuntu Server then updated to Lubuntu Desktop. Thank you for helping me bring a 14 year old system back to life!
Lubuntu is a fast and lightweight operating system. The core of the system is based on Linux and Ubuntu. Lubuntu uses the minimal desktop LXDE, and a selection of light applications. We focus on speed and energy-efficiency. Because of this, Lubuntu has very low hardware requirements.

Hi, as you will know lubuntu is moving to Qt, also ubntu wiki system is looking to use a new WIKI system. It is a chance to vote on an important issue. I'm the proposer so my vote is not public. Even if you vote '0' it is important that you guys and gals can vote and make an input to lubuntu.

Looks like we may have a problem with Intel users after all.
I checked the difference between xubuntu and lubuntu ISO, and this
package is missing :
Intel cards was supposed to work without this package, but according
to the package description, it is only the case for new cards.
If you have people affected by black screen, or no X starting, or no
lightdm starting, with Intel card, could you advise them to install
this package, reboot, and see if it's working (and report back) ?
This should affect only fresh install, upgrade should be fine (as this
package was included in previous releases).
Thanks in advance for your reports.

for those running 16.04 this is a fairly urgent update... Details are in the link. For those non-geeks it is simply
Menu --> System Tools--> Software Updater .... enter passowrd and allow the system to reboot to ensure you have the fixes all installed.

Only thing I miss in Lubuntu is window snapping. I think I'll install xfwm4.

Lets see if I break anything.

+Brendan Perrine Derp. I already got xfwm4 running and I'm now customizing shortcuts. Thanks for the info I should have delved deeper into Openbox. I'll have a look when I set it up on my desktop later this weekend.

Thanks to all the hard work from our contributors, we are pleased to
announce that Lubuntu 16.04 LTS has been released! With the codename
Xenial Xerus, Lubuntu 16.04 LTS is the 10th release of Lubuntu, and
the second long term support release. Lubuntu 16.04 LTS will be
supported until April 2019, with three years of support.


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[1] also
uses well-known applications, such as Firefox, Openbox, Pidgin, to
name a few. The Lubuntu project wiki[2] contains more information on
the project.


On the Ubuntu cdimage server[3], we have images for the following architectures:

-   amd64 (commonly referred to as 64-bit)
-   i386 (commonly referred to as 32-bit)
-   PowerPC (Macintosh images)

The release notes[4] are here if you wish to read them. We have left
out some notes that are common to all flavors, so read the Ubuntu
release notes if you wish.


-   General bug fix release as we prepare to switch to LXQt.
-   Many LXDE components have been updated with bug fixes.
-   The artwork has been updated with more icons, theme updates, a new
wallpaper, etc.


-   Many under-the-hood improvements, such as the replacement of
upstart with systemd. More information is available in the Ubuntu
release notes linked above.
-   A significant amount of LXDE bug fixes and improvements.
-   Massive artwork improvements.
-   lubuntu-extra-sessions: In the past, selecting different sessions
(netbook, gaming etc.) was installed by default. This is now an
optional extra that can be installed by those who want this added


Lubuntu is a good operating system for many old computers, but not for
all of them. Some computers have too little horsepower or memory. A
rule of thumb is that the computer should not be more than 10 years

Memory (RAM)

For advanced internet services like Google+, YouTube, Google Drive,
and Facebook, your computer needs at least 1 GB of RAM. For local
programs like LibreOffice and simple browsing habits, your computer
needs at least 512 MB of RAM.

Processor (CPU)

The minimum specification for CPU is Pentium 4 or Pentium M or AMD K8.
Older processors are too slow and AMD K7 has problems with flash


Nvidia, AMD/ATI/Radeon and Intel work out of the box, or the system
can be tweaked to work fairly easily. You can get help at the Ubuntu
Forums[6]. With such graphics, or if you don't know, try the current
Lubuntu version.


Our support channel is #lubuntu on IRC[7]. If you don’t have an IRC
client, click the link in the earlier sentence, type in a nickname,
press start, state your question and press Enter to speak. We also
have the lubuntu-users mailing list. You do not need to subscribe to
the mailing list to ask a question. Send an email to lubuntu-users AT
lists DOT ubuntu DOT com.


We always need more help! If you would like to contribute, head over
to our Getting Involved page[8]. We need help with Reporting bugs,
Translations, Tests/QA, Code & patches, Artwork, Documentation, and
Marketing/Press. If you have any questions about contributing, please
join #lubuntu-devel on Freenode or email the lubuntu-devel mailing
list[9] at lubuntu-devel AT lists DOT ubuntu DOT com.


For known issues, please see the release notes.


Have a nice day,
on behalf of the Lubuntu team
New Features in Lubuntu 16.04 LTS. Kernel is now the 4.4 LTS kernel to sync with the 16.04 release. General bug fix release as we prepare for LXQt. Many LXDE components have been updated with bug fix releases. An update of the artwork (more icons, theme update, more compatibilities .

About this community

The objective of the Lubuntu project is to create a variant of Ubuntu that is lighter, less resource hungry and more energy-efficient by using lightweight applications and LXDE, The Lightweight X11 Desktop Environment, as its default GUI. Lubuntu is targeted at PC and laptop users running on low-spec hardware that, in most cases, just don't have enough resources for all the bells and whistles of the "full-featured" mainstream distributions. Members of the team take care of LXDE and other packages that are part of Lubuntu. Lubuntu received official recognition as a formal member of the Ubuntu family, commencing with Lubuntu 11.10.

I am not sure what this video should show. htop is known for not being accurate but more like an indicator form ram usage.
Though this test has nothing to do with real experience of the desktops as what happens if I open up some applications on Cinnamon or even open up the calendar or whatever menu it provides. Does the memory usage grow ? Does it grow more rapidly then the usage when I perform similiar tasks on Unity or LXDE or whatever DE ?
Don't get me wrong but the video seems to me that the author doesn't get a thing about memory management on linux.

Too sad that I see such comparisons even more often. and they are mostly useless.

So, umm..
yup, i have an ASUS X401U with 2GB RAM (but the system info just display 1.5GB) and AMD E2 procie with Radoen HD. I used to ran windows 7 ultimate 32bit when i was in high school (i hijacked it haha. but now i'm a good guy) and it ran smooth in my machine. Today I'm running Ubuntu 12.04 64bit but it seems laggy. It seems heavy in my machine, although i'm not doing any tweak. I'm trying to find an OS which could run flawlessly but powerful. So, i come here for a "consultation". How about Lubuntu 16.04 for my machine? or another version of Lubuntu? which one should i install?
Thank you :)

I had a rough time getting compton to load (but success). Composotor setting in settings did not work (it even suggested compton). Autostart using applet or directly editing the file (same thing) did not work. (I put leaf pad in there just to test I was doing it right..yup).
Last was....
Making a shortcut and placing it in the autostart folder of my home config. That Worked!
Compton is awesome.

Lubuntu and Dropbox tray icon: how to get it working?
I installed Lubuntu 16.04LTS on my laptop and everything works just fine except the Dropbox tray icon. Sync works but the applet does not work. I have no control on syncing process (pause, feedback information...). How can i get it fixed?
PS1 : i tried a solution found on a xubuntu forum but it didn't work
PS2 : please do not advise me to install Owncloud instead, it's for my office purpose and i cannot change the cloud service

I think its a bug with dropbox. Launching it via dbus-launch should also bring back the icon.

there is currently a re-build of all the images for lubuntu[1]. We have been told that there will the will be at least one more re-build. A new kernel is coming and other fixes.

Again, those who can test PPC are really needed for us to have this variant out as an LTS.

So, for those who can test, please do.. 

Many thanks,
