I installed lxde on ubuntu server 16.04.3.every thing was fine untill i purged lxde and re-installed it.now i can start lxde with startx,but not with using lightdm or startlxde.



In lightdm it says failed to start session



I tried moving ~/.Xauthority and re installing LXDE.no result,i couldn't find any answer on internet so please don't duplicate my question.



Any help would be appereciated.



EDIT:
when i install ubuntu-deskop,the problem is fixed and i can login to LXDE.but when i purge ubuntu-desktop,the problem is back again.



EDIT2:
I've also purged,removed all packages that where leftover,autoremoved,autocleaned then install LXDE again,but no luck.

  • Verify that you have lightdm-gtk-greeter installed. Otherwise, the screen will freeze on login for some LightDM versions.

I had a similar problem in Ubuntu 18.04 after installing lxde, I would get "failed to start session" when I put in the correct password. (Putting the incorrect password gave a different error.) I did apt-get install lubuntu-desktop and this solved it.
