Title:
Display remains fully dimmed after resume from suspend
Status in linux package in Ubuntu:
Confirmed
Bug description:
After resuming from suspend the display returns fully dimmed, and
display brightness can't be adjusted, neither using FN keys, nor using
KDE power management control. The issue occurs regardless whether the
suspend state was activated by low battery, by closing the display, or
by explicitly selecting sleep mode in KDE. Killing and restarting X
does not solve the problem. A reboot does.
