You have been subscribed to a public bug: Also affects nvidia-graphics-drivers-319
The effect is identical to https://bugs.launchpad.net/ubuntu/+source/fglrx-installer/+bug/958279 but with Nvidia instead of AMD/ATI drivers. 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) ** Affects: xorg (Ubuntu) Importance: Undecided Status: New ** Affects: xorg-server Importance: Low Status: Confirmed ** Tags: amd64 apport-bug precise trusty utopic -- [Dell M4800] DPMS support broken, fails to wake up the monitor after putting it to sleep https://bugs.launchpad.net/bugs/1268151 You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to xorg in Ubuntu. -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
