Bug Description
Binary package hint: kdm
After resuming from hibernate, my screen blanks after about 70 seconds, despite the normal 10 minutes.
If I restart kdm after resume, it works like with a fresh boot.
Additionally, I cannot figure out where the "blank screen" gets invoked from.
I have setup "MatrixView (GL)" in the Screen Saver panel in kcontrol - not "Blank Screen" and even not set it up to "Start automatically".
However, now that I have checked "Start automatically", set it from "After 1 min" to "After 10 min", it does not blank after said 70 seconds anymore.
Even changing it back to "Not start automatically" as before now does not trigger the "blank screen" anymore - like a kdm restart would do.
Just to be clear: moving the mouse brings back the display like before, of course. It's just the triggering that's wrong.

Seems to be related to the "dpms" setting for X.
With the kcontrol module "Monitor & Display" under the "Power saving" tab I've set "Enable power saving" and set it to "Switch off monitor after: 30 minutes".
However, it always blanks before those 30 minutes. About after 10 minutes normally and 1 minute after resuming.
Because this is quite time-consuming and boring to test, I'd like to hear where I should look specifically.
