Hmm, strange that it didn't fix the problem for Frank, because I also tried removing the gnome-screensaver package, and indeed it solved the problem completely!! I can now even switch back and forth with both users running Compiz and all the eye candy.
Now are there any alternative screensavers to gnome-screensaver, and shouldn't this bug rather be linked to gnome-screensaver as well? -- black screen when switching between multiple X session https://bugs.launchpad.net/bugs/529882 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
