It appears that sometimes, nvidia is losing the *display* information. (II) NVIDIA(0): Setting mode "NULL"
I can recover my display by running xrandr --auto Note: this may not work when you are logged into the console - you may want to use something like "sleep 3; xrandr --auto" and then switch via Ctrl+Alt+F7 within three seconds. I usually login from a remote machine. It happens about once a month for me. :-( -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1268151 Title: [Dell M4800] DPMS support broken, fails to wake up the monitor after putting it to sleep To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1268151/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
