Seems quite random... I saved "15 minutes" monitor off time from KDE, checked with "xset -q" that it was:
DPMS (Energy Star): Standby: 900 Suspend: 900 Off: 900 DPMS is Enabled Monitor is On But after log out and log in there was this: DPMS (Energy Star): Standby: 54000 Suspend: 54000 Off: 54000 DPMS is Enabled Monitor is On -- Display does not enter power-save (both tty1 & X) https://launchpad.net/bugs/66026 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
