Ubuntu 12.04: Screen won't enter power down
Hi all,
I am running Ubuntu 12.04 on my Dell Latitude E6410 using the restricted nVidia drivers. For some reason, my screen will not enter power save mode. It goes blank (black screen with the backlight still on), after 10 mins instead of just turning off.
I have also tried doing it manually by using xset dpms force off, however this does the same thing.
This has worked in other distros I have tried, so I'm not sure why this won't work here. Any suggestions?
Cheers.
