Hi everyone,

I have an nVidia Quadro 600 (GF108 ) video card, which has two outputs: one DVI and one DisplayPort. I have two monitors, both Lenovo ThinkVisions, one plugged in by DVI and the other by DisplayPort.

If my screensaver turns on, or I do xset dpms force off, only the monitor plugged in by DVI goes into power saving mode. The monitor plugged in by DisplayPort keeps its backlight on. The DP monitor goes to sleep if I switch to tty1, and its DPMS works if I plug it in by DVI, but I haven't figured out any way to get it to sleep on DP.

I'm using the latest nVidia drivers from apt (295.20-0ubuntu0.1). Of course, there's no xrandr because nVidia doesn't support it with multiple monitors, so my xorg.conf is:
