I am using ubuntu 16.04. However I want to use a light weight desktop environment as a backup, so I install LXDE using:

sudo apt install lxde

I install it successfully with no errors, however when I log out(even reboot) I found no option to login into LXDE environment. What shall I do next?

ps: I don't want to install Lubuntu-desktop.

pss: Must I install lxdm to use LXDE? If installed this, can my unity desktop works well?

Please help.

  • Are you sure you did sudo apt install LXDE? Commands are case-sensitive, so the correct command should have been sudo apt install lxde.

  • @edwinksl I did installed lxde, I've correct the post. Aug 13, 2016 at 13:48

    What does apt-cache policy openbox say? What files does /usr/share/xsessions contain? Is /usr/share/xsessions/LXDE.desktop there?

    No you don't need to install lxdm. Actually lxde-core and lxde-common should be enough to have a working lxde session (both are installed with the lxde metapackage). Maybe you need to reboot so that the lxde session is detected. You can also try sudo apt install --no-install-recommends lubuntu-core which will give you lubuntu session with very few extra applications. Aug 13, 2016 at 14:15
  • @ThanosApostolou Install lubuntu actually works, however I want unity-greeting session to login into either lxde or unity desktop itself. Just don't feel like to install lubuntu, seems not clean enough for me... Aug 13, 2016 at 14:22

I had the same problem and here's the fix: you need to install lxde-common after installing lxde. it includes lxsession and two other packages needed for lxde:

sudo apt install lxde-common

I don't know why dependencies aren't covered in this particular package.

Amazingly, I installed lxsession package and reboot, finding that I have session lxde and openbox.

However, the logout button doesn't work, so I installed lxsession-logout, still I can't logout.

Then I remove lxsession-logout and install lxde-logout and all works. It seems that when install lxde-logout, lxsession-logout is automatically added.

    For me (on current Ubuntu 16.04), installing lxsession-logout does fix it, and package lxde-logout doesn't exist. Apr 12, 2017 at 10:44

In my case there was a problem with the mirror I was using (missing packages), which caused apt-get to install only some of the LXDE required packages so it thought they were all installed

After editing /etc/apt/sources.list and changing the repository, then apt-get update && apt-get install lxde worked fine
