I installed the lubuntu-desktop package with all it's dependencies recently and since then the graphics of my other desktops, Ubuntu, 2d ubuntu and gnome-shell are ruined. By ruined I mean I don't know what happened. It' not just the compositing, compiz is still running and restarting it does nothing.
Another thing I noticed is the lubuntu splash screen shows up during boot and shutdown whether I was in a lubuntu session or not.
Sorry for such little info. any ideas?
