Same issue for me, fixed with comment #22 (thanks!) I moved power* out of ~/.kde/share/config/
I note that once i recreated my power settings, i have only powerdevilrc and powermanagementprofilesrc in the config directory (in terms of power*). The file list that I moved out (power*) included: powerdevil2profilesrc.old powerdevil.notifyrc powerdevilprofilesrc.old powerdevilrc powermanagementprofilesrc I also noted the following in /var/log/syslog, don't know if it's related: Nov 24 18:02:48 caseylinux dbus[1102]: [system] Activating service name='org.kde.powerdevil.backlighthelper' (using servicehelper) Nov 24 18:02:48 caseylinux org.kde.powerdevil.backlighthelper: QDBusConnection: system D-Bus connection created before QCoreApplication.

This started for me at random... i recently updated to 12.10, but it's been running fine for a few days. This just happened when I started up this last time (didn't reboot to see if it continued). I also have a dead battery (flashing orange battery light on Dell Inspiron 6000), which failed maybe 4 or so boots ago. -c -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/952521 Title: Screen blanking and dpms can't be turned off To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/952521/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
