I messed up ccsm, and I was forced to run
gconftool-2 --recursive-unset /apps/compiz-1
unity --reset
unity --replace
After I ran that, I began noticing small glitches in Gnome (Unity works fine): I can't move windows and the autorun prompt won't start. The windows glitch doesn't cause much of a problem, but I really like the autorun prompt and can't start it by pressing alt-f2 or by clicking the autorun prompt in the Applications menu. How do I fix these?
