Public bug reported:
most of the time when i do a software update that involves installing a
new kernel, the laptop fails to properly restore the screen when
returning from the suspension. (i always reboot after doing the update,
that is not the problem).
I can "fix" this by getting into the power management configuration and
changing something (pretty much anything) and then changing it back.
Once i do this, the computer works properly after a suspend.
It behaves "as if" there were some persistent state whose format or
location changes in an incompatible way with each kernel release and
that this gets reset by the power management app but is not cleared by
the update process.
this is an amd based machine with amd based graphics.
