xscreensaver seems to be partially to blame. After uninstalling it, logging out and logging in, xset q reports
Screen Saver: prefer blanking: yes allow exposures: yes timeout: 240 cycle: 600 ... DPMS (Energy Star): Standby: 600 Suspend: 0 Off: 900 DPMS is Enabled Monitor is On So the 4 minute blanking timeout is now respected, but the DPMS timeout has been set to 10 minutes instead of the requested 6 (and the DPMS off time has been set to 15 minutes, instead of 0 as in the xset command written by light-locker-settings). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1291017 Title: light-locker blanking settings not taking effect To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/light-locker-settings/+bug/1291017/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
