Bug Description
Binary package hint: gnome-power-manager
gnome-power-manager sometimes fails to switch off the display after the selected timeout.
I executed it with the --verbose switch and collected the log.
In a normal session I don't see the messages
DPMS not enabled
failed to turn on DPMS: DPMS is not enabled

I discovered that DPMS fails when I boot an instance of android emulator, which is a 32bit app in my 64bit ubuntu.
After clicking start->launch on the emulator, g-p-m starts to print the error when the screen timeout occurs, and even after exiting from the emulator this problem remains. Restarting g-p-m does not help.
The only way to solve this is to run 'xset dpms force off' and g-p-m will automatically recover itself.
