Seems this bug still persists in 14.04 I use 'xset dpms 0 0 1200 -dpms s off s noblank s noexpose' in my .profile but something keeps switching dpms back on.
Even if I use xset -dpms in a teminal something re-enables it. I am also suffering from having to hit a key every 10 mins or so when watching a video in vlc. xset - q reports: DPMS (Energy Star): Standby: 600 Suspend: 900 Off: 1200 DPMS is Enabled Monitor is On shortly after having issued xset -dpms. After no keyboard activity for some minutes a notification is displayed, near the bottom of the screen, showing a brightness setting (a screen icon, a 'progress bar' and a percentage) which usually begins at 60% followed some minutes later by one showing 40% then later 0%. Despite the notification the screen does not dim but does eventually blank. The function keys (F6 and F7) do work to adjust the screen brightness, though no notification is displayed. It used to be that a brightness notification (different format, a sun icon and a thinner 'progress bar') was displayed on the upper-right of the screen. I don't have xsreensaver. My power setting in the control centre is set to suspend after 30 mins of inactivity when on battery and not suspend when plugged in. In Brightness settings I have full brightness, dim unchecked and blank set to never. I'm running kubuntu 14.04 on a Toshiba NB-200. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to x11-xserver-utils in Ubuntu. https://bugs.launchpad.net/bugs/1019312 Title: xset -dpms does not disable power saving Status in “x11-xserver-utils” package in Ubuntu: Confirmed Bug description: The key issue is that I cannot watch films, since my display turns off every 10 minutes, with AC plugged in.
