I finally found out what the problem is. gnome-screensave wasn't installed.
Sorry for wasting your time, but still, how can this even happen? I just did an aptitude dist-upgrade and I saw that gnome-screensave was reccommended, but not installed. I guess this won't happen on a new installation now, right? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/950005 Title: screen doesn't lock when pressing ctrl+alt+l or using action from system menu To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-screensaver/+bug/950005/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
