LightDM is installed and running by default as a part of the Beta release. Yet, LightDM is not displayed at login time, rather a primitive, GDM like manager is the one we find at login time.
I tried the command
sudo dpkg-reconfigure lightdm
which gave the result :
dpkg-maintscript-helper: warning: environment variable DPKG_MAINTSCRIPT_NAME missing dpkg-maintscript-helper: warning: environment variable DPKG_MAINTSCRIPT_PACKAGE missing
while,
sudo stop gdm
gives
stop: Unknown job: gdm
(as GDM is not installed in the Beta Release)
sudo start lightdm
gives
start: Job is already running: lightdm
So now, how do we make LightDM appear at login time?
Best Answer
Run the following in a terminal:
sudo apt-get update && sudo apt-get install lightdm
That should resolve your issue.
