Comment 10 for bug 1155838

regarding comment #3 from Bryce, the monitors.xml is not an issue here; I've moved this aside and still been able to reproduce it, and I've reproduced this also with a completely clean guest account.

It is not specific to the mainline kernel; it's reproducible both with the raring kernel and with the other (Ubuntu) test kernels I was running.

I'm attaching two files, xrandr-good.txt and xrandr-bad.txt, for xrandr --verbose output with and without corruption respectively. In the 'bad' case, the corruption appears on the HDMI output - but this is not always true; it may appear on one output or the other.

I can't say I see anything that points to this being a gnome bug, as I can reproduce the problem when calling xrandr directly to set the mode ('xrandr --output LVDS1 --pos 1680x0').
