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 Desktop Packages, which is subscribed to gnome-screensaver in Ubuntu. https://bugs.launchpad.net/bugs/950005 Title: screen doesn't lock when pressing ctrl+alt+l or using action from system menu Status in “gnome-screensaver” package in Ubuntu: Incomplete Bug description: On Ubuntu precise with all current updates, locking the screen does not work.
