I have a variation on this, I hope this is the correct place to report it rather than open a new issue for something that would seem closely related.
ctrl-alt-L works for me, it locks the screen but it does not switch off my displays, they just go "blank screen" but still powered on. If instead I click on the top-right -> lock it locks the screen and switch the display to power save, i.e. off. The same goes for opening terminal and type 'gnome-screensaver-command -l', that also works correctly. I tried going to System Settings -> Keyboard -> Shortcuts -> Custom Shortcuts, create new shortcut, entered "gnome-screensaver-command -l" (and various variations of this, including starting with bash -c), then set this to ctrl-alt-L -- but then the ctrl-alt-L combination is completely ignored. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to the bug report. https://bugs.launchpad.net/bugs/1215816 Title: CTRL+ALT+L dont lock screen on Ubuntu 13.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1215816/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
