[Bug 367263] [NEW] System freezes during stop of X-Server

[robs]

Public bug reported:

Binary package hint: xserver-xorg-video-intel

Hi,

I am using mythbuntu, and updated the system from 8.10 -> 9.04.
Everything works (more or less) fine, but I still have a problem with
the graphics. If I want to shutdown/reboot, all programms terminate, the
screen gets black, but the system does not shutdown/reboot, and the
system is not longer reacting (console, ssh, ping). It´s a classical
freeze.

The same  happens if I want to restart the X-server by sudo
/etc/init.d/gdm restart.

After reeding the release notes of 9.04, there are some hints about
problems with intel graphics. So I added 'Option "DRM" "OFF"' to
xorg.conf, and the problem was gone.

The switched off DRM option has no real pain for me, because I use the
computer only as a mythtv backend and fronted, so high performance
graphics are not so importand.
