I think it enters on loops called by gnome-wm script. In a pstree you can see:
-gnome-session- | |-gnome-wm---compiz---gnome-wm---compiz---gnome-wm---compiz---gnome-wm---compiz---gnome-wm---compi+ gnome-wm calls compiz that is a shell script that in the last line have: /usr/bin/compiz.real $COMPIZ_OPTIONS "$@" $COMPIZ_PLUGINS || gnome-wm But if you doesn't have composize in X, compiz.real will fail so it launch gnome-wm again. The problem, IMHO, is why gnome-wm launch compiz when there are not composite extension in X. -- compiz spawns thousands of processes https://launchpad.net/bugs/97053 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
