Bug#427721: occasionally freezes hard using xrandr on 855GM
Package: xserver-xorg-video-intel
Version: 2:2.0.0-4
Severity: normal
This is a tracking bug for upstream bug #10664
https://bugs.freedesktop.org/show_bug.cgi?id=10664
There is some kind of instability in switching between one screen (LVDS)
and two (LVDS+VGA), and backwards and forwards. The first switch seems
stable, but with the second and then third switch the system
occasionally freezes solid.
It does not happen every single time so I'm not sure exactly where the
reproducibility is. I seem to most often be able to go from one
screen to two and back to one, then the freeze occurs returning back
to two again. But sometimes it happens just going from one to two and
back to one again. It seems to be triggered by running xrandr (which
I need to run in order to readapt to the new number of screen).
