I have not uninstalled or disabled compiz, for I have not found a single trace of it in my system, no mention on the running processes or installed programs. Of course I can be wrong, or unable to look at a correct place. As I understood it, compiz is some sort of system to create visual effects for ubuntu? I for one have such a poor graphics card (integrated SiS card) that can do no visual effects, so all of them are disabled. Just to be on the safe side, here is a list of the processes that are running on my system, so if you can tell me anything, it would be very helpful. Thank you already for all the help you have given. PID TTY STAT TIME COMMAND 7657 ? S 0:04 gconfd-2 7673 ? Ss 0:00 dbus-daemon 7711 ? Ssl 0:00 bonobo-activati 7716 ? S 0:00 gvfsd 7734 ?
