Public bug reported: If the user locks the screen via the Lock Screen action (Ctrl + Alt + L), the screen should be turned off. What happens now is that the screen goes black, but the backlight remains on, consuming the battery and serving as an unnecessary light source. Only after the number of minutes specified in the Brightness and Lock settings panel elapse is the screen turned off.
I see no reason why this should be like this: the "Turn screen off when inactive for: X minutes" setting is, I guess, there to recognize the situation when the user forgets to log out / put the machine to sleep when he leaves it. However, when the user locks the screen, it is, in effect, a way to tell the OS "I'll be inactive". So, it would only make sense if the screen was turned off. I am using Ubuntu 12.04.2 LTS. ** Affects: ubuntu Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1114614 Title: Lock screen action should also turn the screen off To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1114614/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
