Comment 20 for bug 385633

I am also having this problem, on a fresh Karmic alpha 6 install, desktop system with Nvidia 9600GT card. I have 2 monitors in a Twinview configuration.

screens will blank, but never sleep.

'xset dpms force off' does not cause the monitors to sleep, they just blank (this command doesnt work in my jaunty installation either, but dpms sleep is working on that).

'xset dpms 0 0 60' does cause the monitors to go to sleep.

also noticed that grub2 broke dpms on my jaunty installation.
