I've been having a problem with my main user account ever since I installed Lucid where after I enter my login credentials, the desktop always freezes. Since I've been having this problem, I created another user and have been able to login fine with this one. I have determined that the problem is with compiz, so I want to completely reinstall compiz, including any configuration settings. However, there seem to be a number of packages that go with compiz so I'm not sure what steps I can follow to accomplish this. Can anyone tell me the steps I need to take?
