[Bug 1268151] [NEW] [Dell M4800] DPMS support broken, fails to wake up the monitor after putting it to sleep

 

You have been subscribed to a public bug:

Also affects nvidia-graphics-drivers-319

The effect is identical to https://bugs.launchpad.net/ubuntu/+source/fglrx-installer/+bug/958279
but with Nvidia instead of AMD/ATI drivers.

HW is Dell Precision M4800 with GK106GLM [Quadro K2100M] and QHD+
display

Once the display shuts off, it will not be woken up anymore and the screen stays dark.
Only a restart of the Xserver will bring back the display at that point.

A cycle of
xset dpms force off; sleep 30; xset dpms force on
will leave the display dark.

At the moment I help myself by not allowing DPMS to switch off the display:
neuffer@charion:~$ xset dpms 0 0 0

neuffer@charion:~$ xset -q -d :0.0
