I can't reproduce now because when I hit ctr-alt-backspace X doesn't restart anymore, I stay in text-mode console and has to run "sudo /etc/init.d/gdm restart". Then gnome-screensaver is started.
Some times ago (when X restarted after killing him) I was able to reproduce the bug, but i not waited 1 minute to see if it starts... -- gnome-screensaver not started in session https://launchpad.net/bugs/35211 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
