Compositor Crashing in 15.10

Asked by Noah Young on 2015-12-10

Since installing 15.10 I've been experiencing problems with my desktop compositor crashing or misbehaving (for instance having the task bar disappear from all virtual desktops except 1, or having long pauses in graphics rendering after moving a window).

Here is the output from the command suggested at https://help.ubuntu.com/community/GraphicsTroubleshootingProcedure
