Title:
X stops responding to input on power saving mode
Status in linux package in Ubuntu:
Incomplete
Bug description:
Once my session has been locked and the screen off, Xserver stops responding
to input ( I can still move the cursor). I can re-activate it by typing in a
tty "xset dpms force on".
If I just lock the screen all works fine.
If I just turn off the monitor (xset dpms force off) all works fine.
The same system (kubuntu 16.04 64bit) on different hardware (nvidia)
has no problem.
