"xset dpms force off" has no effect. "vbetool dpms off" does turn off the backlight. Using nvidia proprietary driver, "xset dpms force off" turns off backlight but then has other issues ( https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics- drivers-331/+bug/1268151 ) Curiously, and possibly related, "xset s activate" (via ssh and/or using sleep 1) has no effect. It does not blank the screen. Possibly related, from Xorg.0.log: [ 27.193] (II) NOUVEAU(0): No DPMS capabilities specified version: nouveau from kernel 3.16.6-gentoo.

HW is Dell Precision M4800 with GK106GLM [Quadro K2100M] and QHD+ display Once the display shuts off, it will not be woken up anymore and the screen stays dark. Only a restart of the Xserver will bring back the display at that point. A cycle of xset dpms force off; sleep 30; xset dpms force on will leave the display dark. At the moment I help myself by not allowing DPMS to switch off the display: neuffer@charion:~$ xset dpms 0 0 0 neuffer@charion:~$ xset -q -d :0.0 Keyboard Control: auto repeat: on key click percent: 0 LED mask: 00000000 XKB indicators: 00: Caps Lock: off 01: Num Lock: off 02: Scroll Lock: off 03: Compose: off 04: Kana: off 05: Sleep: off 06: Suspend: off 07: Mute: off 08: Misc: off 09: Mail: off 10: Charging: off 11: Shift Lock: off 12: Group 2: off 13: Mouse Keys: off auto repeat delay: 500 repeat rate: 20 auto repeating keys: 00ffffffdffffbbf fadfffefffedffff 9fffffffffffffff fff7ffffffffffff bell percent: 50 bell pitch: 400 bell duration: 100 Pointer Control: acceleration: 2/1 threshold: 4 Screen Saver: prefer blanking: yes allow exposures: yes timeout: 0 cycle: 0 Colors: default colormap: 0x20 BlackPixel: 0x0 WhitePixel: 0xffffff Font Path: /usr/share/fonts/X11/misc,/usr/share/fonts/X11/100dpi/:unscaled,/usr/share/fonts/X11/Type1,/usr/share/fonts/X11/100dpi,built-ins DPMS (Energy Star): Standby: 0 Suspend: 0 Off: 0 DPMS is Enabled Monitor is On ProblemType: Bug DistroRelease: Ubuntu 14.04 Package: nvidia-331 331.20-0ubuntu9 ProcVersionSignature: Ubuntu 3.11.0-15.23-generic 3.11.10 Uname: Linux 3.11.0-15-generic x86_64 NonfreeKernelModules: nvidia ApportVersion: 2.13.1-0ubuntu1 Architecture: amd64 Date: Sat Jan 11 12:06:30 2014 InstallationDate: Installed on 2014-01-07 (3 days ago) InstallationMedia: Xubuntu 13.10 "Saucy Salamander" - Release amd64 (20131016) SourcePackage: nvidia-graphics-drivers-331 UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/dell/+bug/1268151/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
