Comment 11 for bug 1181666

I seem to also be having a similar issue as well. My mouse can move around and shows hover state on the top menu bar, but can't click on anything. I however can't use the keyboard shortcuts to pull up anything. The only shortcuts I am able to use is the ctrl+alt+F1-7 keys. For which that sometimes fixes the issue by bouncing over to one of them then back to the the original shell ie F7. I tend to have to do this shortly after logging in every time. It seems to have gotten more problematic with the upgrade to 13.10 from 13.04.

However the bouncing shells trick sometimes works, but at a random time it stops working. To which I have tried running "export DISPLAY=:0.0; gnome-shell --replace". Which doesn't appear to work for me, and results in a gnome shell where the top bar is missing as well as any boards & title bars on windows. The mouse can still move around at this point, but requires be to do a full restart to get back into a functional state. To note I do see a OpenGL exception after running the replace. Next time this happens I'll try to record the exception.

Is there any logs I can try to pull for you that may help? As I can consistently get into this bad state with a logout & back in, but takes some time to get into the real bad state. Requiring a reboot.
