Bug also affects me. In my case I didn't notice the issue until clicking "export settings" (but could have initiated by selecting preferences). To explain further, unity is "gone" (dash and top panel). Upon reboot, get the "global menu" of nautilus as a "top panel" and nothing else. Could start a terminal session, but then it hung as well forcing a "hard reboot" and then went into Unity 2D.
In Unity 2D I deleted the ~/.config/compiz-1 and the ~/.compiz-1 folders. Then, logging out of 2D and back into 3D has things "working again" (of course any changes to ccsm are lost). So, definitely corruption in those areas (deleted both of them at once so couldn't isolate down to one of them being the problem). I don't know if it is applicable, but the only changes I had made in ccsm prior to clicking on the "export settings" button were to the Unity Plugin: launcher icon size, automaximize value and to the Grid Plugin: keyboard bindings and the "top edge" binding. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/869840 Title: compizconfig-settings makes Unity dekstop unusable forever To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/compizconfig-settings-manager/+bug/869840/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
