After sleep or hibernation the DPMS settings go nuts

[Rui Matos]

Version:

gnome-power-manager 2.16.1-0ubuntu2

I've set the "Put display to sleep" both in AC and battery to the minimum allowed which is 4 minutes. With 'xset q' I can see:

DPMS (Energy Star):
  Standby: 0 Suspend: 0 Off: 0
  DPMS is Enabled
  Monitor is On

Which is not what I configured but seems to work somehow. Now, when the laptop wakes from sleep or hibernation (but not everytime) these values change:

DPMS (Energy Star):
  Standby: 60 Suspend: 60 Off: 120
  DPMS is Enabled
  Monitor is On

Which turns off the backlight after 1 min and is _really_ anoying. I've then noticed that if I set the preferences to 7 minutes these values become 240, 240 and 480 respectively (but 0, 0, 0 when the computer boots). This is more bearable.

Anyway, I think there are actually two bugs here, one is that the advertised values aren't exactly what is set (though they seem to work when the X server thinks they are 0, 0, 0). The other is that after sleep everything goes nuts...

Very similar bug(s) have been reported under KDE, so I suspect this is some general breakage in recent Edgy. See bug 65791 (and its duplicated bugs).

Thank you for taking the time to report this bug and helping to make Ubuntu better. The issue that you reported is one that should be reproducible with the live environment of the Desktop CD of the development release - Gutsy Gibbon. It would help us greatly if you could test with it so we can work on getting it fixed in the next release of Ubuntu. You can find out more about the development release at http://www.ubuntu.com/testing/ . Thanks again and we appreciate your help.
