I installed the Atlantis transparent cube plug in and now all i have on my screen are folders and fish. I cant open a terminal with ctr alt T and i cant open the run dialogue box with alt F2. I also cant get ctr alt F1 to do what i need (unity --reset). I have tried everything that i can think of and nothing is working. I have been using the computer in guest mode but i cant do this forever, at least i hope not.
If you have another DE such as gnome shell you can configure compiz(by pressing reset button in preferences) from it and re-log to Unity read this also.
