Hello Mystilleef, Mystilleef [2012-04-24 4:22 -0400]: > What upower dbus signal do I need to listen to when my > laptop screen is turned on or off by gnome-screensaver or > gnome-power-manager?
None. This is not the domain of upower, nor kernel uevents. This is not even an XRandR event (which also sends notifications, but different ones). I believe gnome-screensaver just uses the equivalent of "xset dpms force off" (through a library interface). However, I am not aware that DPMS provides notifications, and [1] and its lack of responses do not rise my hopes. > The solution I've found so far is to run a script that > resets the screen after a resume operation.

So I take it this "sleep" is not "suspend to RAM", but you mean "switching off the monitor on idle"?
