Description guy 2013-04-02 23:04:12 UTC

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.

Doesn't seem to be a problem anymore in 3.10 kernels
