Bug#613571: xserver-xorg-video-nouveau: VGA screen flickers when accessing card0-TV-1/status



Hi,

Vincent Bernat <bernat@debian.org> (15/02/2011):
> I am using a dual monitor setup. Since recently, my VGA screen
> started to flicker every minute. It starts flickering as soon as GDM
> is up. I have discovered that the culprit is upowerd which queries
> the following file:
> /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0/drm/card0/card0-TV-1/status
> 
> Querying this file by hand makes the screen flicker. I have no TV
> out on my card. I also have the flickering when using "xrandr"
> command. I suppose it is querying the same file.

> I will try to pass tv_disable=1 to nouveau module and keep you informed.

doesn't that look like a kernel bug?
