- Ubuntu 18.04.4 LTS
- ubuntu-desktop 1.417.4
- ubuntu-unity-desktop 0.1
- lightdm 1.26.0-0ubuntu1
Starting off from a GNOME enviroment, I have run
sudo dpkg-reconfigure lightdm, chosen lightdm as default, exited with no error message, and rebooted.
cat /etc/X11/default-display-manager gives
The new greeter is lightdm/Unity-style, but the eventual desktop environment is GMD again (all works in it). This happens all the time. The switch to lightdm has been stable, though, in another laptop with the same versions as above. So, this is not impossible.
- Which settings make it so that lightdm/Unity does not proceed beyond the greeter?
- What should I look into and edit?
- Ubuntu 18.04 lightdm does not work properly: gdm pops again after the screen goes into locked mode.
