I have been experiencing the same problem, first with 11.10 and now with 12.04. i965.
It has happened a few times today and I tried the following commands from VT1: export DISPLAY=:0; xset dpms force off; sleep 5; xset dpms force on The commands appeared to run without error but it did not fix the problem. As before, the only option is pkill X or to reboot. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/763422 Title: [i965] idle black screen plus other issues Ubuntu 11.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/763422/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : [email protected] Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
