After upgrading to Gnome 3.6 and subsequently switching to systemd Gnome's automatic screen dimming to save power is no longer working. I checked the value and it is set for 90 seconds, but as I said, it isn't working. Is anyone else experiencing this? Does anyone have any suggestions on how to correct the problem? I found a similar issue on a Fedora blog that complained of the screen not undimming after dimming. I am unsure if these are related issues, but here is that post: http://forums.fedoraforum.org/showthread.php?t=263072
Stand up and be counted!
