I can confirm this problem too. Stationary PC with Radeon HD6800, Kubuntu 16.04. Monitors do not turn off after certain set time. Only user session locks and goes to login screen.
I've tried Leon's Murer's command "sudo sh -c 'vbetool dpms off; read ans; vbetool dpms on'" and it turns off screens. -- You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to kubuntu-meta in 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 -- kubuntu-bugs mailing list kubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
