Public bug reported:
The screen freezes (with no corruption) when the PC enters standby or screen
power saving.
The event does not happen when the PC enters standby or screen power saving
from the users selection screen.
Once the problem happens the only way to recover normal operation is to switch
to another VT (ctrl+alt+f*), login as any user and run "sudo service lightdm
restart".
Until some of the last updates, I was experiencing very serious episodes
of screen corruptions that forced me to disable hardware acceleration.
Now I can use acceleration with this residual problem.
