After installing XFCE on my ubuntu system, I tried enabling compiz with:
compiz --replace ccp &
However, I have since been unable to remove compiz from the XFCE login. I tried killing compiz, and now I don't have any window manager, and opening the "Window Manager" and "Window Manager Tweaks" pages in the settings panel brings me to an empty page.
Since I've never really played around with XFCE much I have no idea what window manager it uses. So I don't know how to phrase reverting it to the old one.
How can I revert back to the old manager?
