Comment 36 for bug 1424013

Ok, this bug is back again.

Here is what occured.

After unchecking the X11 sync a few weeks ago, I noticed that all of my window menus were missing.

While poking around in CCSM to remedy this problem I accidentally clicked on "restore defaults." This caused unity to be disabled somehow.

After restoring unity and compiz settings, I tried to log in but got artifacts and the 100% cpu with compiz problem.

I just need the computer to work, but it is failing. I cannot use Nouveau because I get the "GPU lockup" issue.

Townsend, I installed your ppa and it didn't fix it, there was no change.

I've removed (and purged) all nvidia drivers, unity, ubuntu-desktop, lightdm and reinstalled them. I've deleted my xorg.conf and let a new one be made.

I'm at a loss with nothing else to do, any suggestions are welcome.

Thanks,
I unchecked X11 sync again, but there is no change. Unity bar is artifacted and compiz is using large amounts of CPU.

I double checked glxinfo output in case something got messed up there, but it remains the same as before.
