Comment 20 for bug 129152

Installed the latest updates 30 minutes ago. New kernel required reboot and now I am back to the same problems. If I turn on desktop effects I'm back to 2 workspaces and unable to change. Turn off desktop effects and I can add workspaces. This is all with open source ATI drivers. Using ATI proprietary drivers I cannot turn on desktop effects at all. Booting into older kernels makes no difference, so It's not the kernel. I'm not sure what got updated in todays update, but something in it broke desktop effects again.

Nearly forgot. After the first reboot into the new kernel post update, my screen resolution had been lowered from 1280x1024 to 1024x768.
