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.

    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.

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.

    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
