This bug still affects Ubuntu 14.04. I tried the workaround by Installing xscreensaver and disabling it, but all that does is showing the mouse cursor on the blank screen.
Use case: 1. Connect laptop to external monitor. 2. Show information on external monitor. 3. Close lid on laptop. 4. Keep showing information on external monitor. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1012277 Title: Closing laptop lid should not blank external monitor To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-power-manager/+bug/1012277/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
