Bug Description
On a machine with only one display (VGA), the kernel is reporting two:
grep . /sys/class/
/sys/
/sys/
ls /sys/class/drm
card0 card0-LVDS-1 card0-VGA-1 renderD128 version
grep . /sys/class/
/sys/
/sys/
which then triggers bug 1760849 and the login screen is never visible.

I've changed #WaylandEnable= false to WaylandEnable=false and reboot the system,
after splash there is nothing so I entered into VT with Ctrl+Alt+F2,
it shows a message, 'a start job is running for hold until boot process finishes up.'
I reviewed this bug https:/ /bugs.launchpad .net/ubuntu/ +source/ gdm3/+bug/ 1779476 and installed haveged but does not solve the issue
