Really, no one else has this problem. FWIW, it's not a hardware problem. If I run:
sudo sh -c 'vbetool dpms off; read ans; vbetool dpms on' Then the screen turns off and then turns back on when I hit enter. (See http://askubuntu.com/questions/62858/turn-off-monitor-using-command-line ) So, there must be a problem in some higher level piece of software . -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1474534 Title: Screen Energy Saving and Dim Screen do not work reliably To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/kubuntu-meta/+bug/1474534/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
