Desktop crashes on startup

I am running jaunty on a dell d620. Everything was running fine, including compiz. I made some changes through the gnome interface to add more effects. Since then, after I login, the desktop starts up but the moment I mouseover any menu items, black boxes start to appear and the desktop becomes completely unusable. I switched to the command line console and restarted gdm which allows me to operate on a different display console. I have tried removing and reinstalling compiz with every method I could find. No use. If I leave compiz uninstalled, I am missing window titles and I cannot move windows or switch between them. I have tried to get back to where I was but I am not having any luck. Any help would be appreciated.

When I run compiz --replace, this is the output:
