[Bug 1375528] [NEW] LightDM Chimes but No login screen or TTY

 

Public bug reported:

When booting, LightDM greeter sounds but screen is black. This happens
if I logout as well. TTYs are also blank when lightdm does not start.
Screen will flicker but no terminal will show up. Closing the lid of the
laptop to make it go to sleep and re-opening to wake the machine up
allows me to see lightDM login screen.

Every once in a while, the login screen will appear as normally on a
really cold boot.
