Bug#464793: xserver-xorg-video-intel: VT switching after using OpenGL and second display produces system freeze
So I found out what was going wrong. The solution turned out to be
pretty straight forward, I just had to add
Option "ForceEnablePipA" "true"
to my xorg.conf. I tested this with the driver form unstable
(2.2.0.90-3) and git master branch. No more crashes since yesterday.
As requested in the intel man page, I filed a bug upstream about this:
https://bugs.freedesktop.org/show_bug.cgi?id=14521
Seems I should read man pages more often...
Sorry to have bothered you and thanks for the great support.
Regards,
Soenke
