[Pkg-utopia-maintainers] Bug#619343: Bug#619343: screen still blinks

Thu Apr 28 20:44:32 UTC 2011

I still experience screen blinking in Debian Testing with upowerd 0.9.9,
desktop system with ASUS P7P55D mobo

Symptoms: Screen double blink every 10 seconds.  Occurs, not surprisingly,
in virtual console.  Killing upowerd reduces blink to once every 10 seconds,
so some other poll event is also causing problems.  Changing or disabling
gnome-power-manager has no effect.  Changing screen resolutions has no
effect.

Graphics card is Nvidia GeForce 9500GT, using nouveau driver.

Booting with 'nomodeset' kernel parameter prevents problem, but screen
resolution is reduced to 800x600 from 1280x1024.

Daemon:
  daemon-version:  0.9.9
  can-suspend:     yes
  can-hibernate    no
  on-battery:      no
  on-low-battery:  no
  lid-is-closed:   no
  lid-is-present:  no
  is-docked:       no

Screen blinks in conjunction with this upowerd debug output (repeats every
10 seconds):
