Comment 36 for bug 47775

I stopped using xrandr (and bought an LCD monitor so I can use a dual-head layout at home as well as at work instead), but occasionally my laptop freezes. This happens most often after switching to a different workspace in metacity.

I would not be surprised to discover there are many bugs. One of them can be triggered by xrandr/mode switching and MergedFB, so let's keep this bug report focused on that one.
