Yes, thanks. The issue may be with gnome-screensaver, and not with gnome-power-manager. Can you try to uninstall gnome-screensaver (from a terminal)
sudo apt-get remove gnome-screensaver and install sudo apt-get xscreensaver and see if the issue persists? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/876522 Title: black screen when dim screen to save power To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-power-manager/+bug/876522/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
