Starting lightdm Just Hangs

[kenmoremathguy]

I am on Server 14.04.1 with ubuntu-desktop installed.

I modified /etc/defaults/grub to launch in text-only.

I want to be able to run "sudo lightdm" when I occasionally need access to GNOME.

When I run "sudo lightdm", the screen goes blank for one second. After that, the screen returns to the command line. The lightdm executable has not finished; I need to press Ctrl-C to enter the next command in the shell.

I checked --debug and the logs. Nothing useful. Automatic login should be disabled.

sudo start lightdm

Or even:

sudo service start lightdm

I usually use:

sudo startlightdm

Works for me. ;)
