I updated from 12.04 to 13.04 going through 12.10. I like gnome-shell but after the update gnome-shell was not working properly, it looked the the composting was not working, and it didn't start working until I install the "gnome" package. Now I want to use xscreensaver, so I have to remove gnome-screensaver, which If I try to the system wants to remove gnome and gnome-core, which messes with the composting and no gnome-shell after that.
So how can I remove gnome-screen saver so that I can use xscreensaver?
Thanks in advance for the help
