I was looking for a way to switch to gdm3
from lightdm
, when I found this answer.
So I tried to apply it, and entered sudo dpkg-reconfigure gdm3
, then a selection screen appeared with 2 options: gdm3
and lightdm
. It was the same screen that appeared during the installation of GNOME (using sudo apt install ubuntu-gnome-desktop && gnome-shell
). I chose gdm3
then pressed Enter, then I got this error:
gdm.service is not active, cannot reload.
invoke-rc.d: initscript gdm3, action "reload" failed.
Any ideas?
UPDATE
It turns out that it just required a reboot to work. But I still want to know the meaning of that error I got. Does anyone have any explanation?
