I'm affected by this bug as well. I have two identical monitors attached to a
GT610 DVI and VGA ports. Dual display works (configured thru xorg.conf). I'm
using nvidia 331.38 from nvidia-331-updates driver. Randomly, an unknown
process "resets" my monitor config (third line):
Xorg.0.log:
[ 3043.682] (II) NVIDIA(GPU-0): Display (LG Electronics 22EA53 (DFP-0)) does
not support
[ 3043.682] (II) NVIDIA(GPU-0): NVIDIA 3D Vision stereo.
[ 3114.626] (II) NVIDIA(0): Setting mode "NULL"
[ 3114.790] (II) NVIDIA(0): Setting mode "VGA-0: nvidia-auto-select @1920x1080
+0+0 {ViewPortIn=1920x1080, ViewPortOut=1920x1080+0+0}"
Apparently its related to this service 'org.freedesktop.nm_dispatcher':
May 16 11:03:05 xxxxxxxxx dbus[593]: [system] Activating service
name='org.freedesktop.nm_dispatcher' (using servicehelper)
May 16 11:03:05 xxxxxxxxx dbus[593]: [system] Successfully activated service
'org.freedesktop.nm_dispatcher'
A simple "xrandr -q" restores my settings but it's very annoying...
