[Bug 1268151] Re: [Dell M4800] DPMS support broken, fails to wake up the monitor after putting it to sleep
I contacted Dell support about the issue, and in addition to being
requested to upgrade the BIOS, I was also pointed to this new driver
package:
http://www.dell.com/support/home/us/en/04/Drivers/DriversDetails?driverId=V9HNV
I have not yet tried is, as it might only work for 12.04 Dell branded
Ubuntu, but I see that it contains many .deb files that might work for
newer versions too, including Nvidia drivers and "screen-resolution-
extra[..].deb".
Does anyone running the original Dell supported Ubuntu version see this
issue? If so, does the driver package above solve the problem?

putting it to sleep
Status in xorg package in Ubuntu:
Incomplete
Bug description:
With my Dell Precision M4800, GK106GLM [Quadro K2100M], QHD+ display, and either nvidia-graphics-drivers-331 or nvidia-graphics-drivers-319 once the display shuts off, it will not wake up anymore, and the screen stays dark. A cycle of the following will leave the display dark:
xset dpms force off; sleep 30; xset dpms force on

WORKAROUND: Don't allow DPMS to switch off the display:
xset dpms 0 0 0
xset -q -d :0.0
