                    displays causes X to hang

          Severity: major
    Classification: Unclassified
                OS: Linux (All)
          Reporter: guy at member.fsf.org
          Hardware: x86-64 (AMD64)

         Component: Driver/nouveau
           Product: xorg

I use an xrandr to set up a dual display configuration.

A recent upgrade of the kernel supplied by the Debian "testing" distribution
caused the script to cease to function and additionally cause my system's GUI
to lock up.

The debian package maintainer for the nouveau driver suggested it may be a
problem with backported kernel components and advised me to try a 3.8 kernel
from the "experimental" Debian repository, which I did.

The 3.8 kernel didn't fix the problem: I still can't get the second display to
work, but the xrandr script no longer caused the GUI to lock.
