I can confirm the problem. - screen freezes - mouse moves, but does not change cursor - Ctrl-Alt-F1 does not work (text terminal) - Networking works and I can ssh into my computer HW: Dell XPS 14Z graphic: intel + optimus nvidia (switched off during freeze) It happens randomly. Usually while using web-browser (that's what I mostly use). As I can ssh I can try to get some log files next time. I have noticed: /sys/kernel/debug/dri/0/i915_error_state /var/log/Xorg.0.log Let me know if you need anything else. I have tried to kill some processes, but the screen was still frozen. Killing X-server helps. -- 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/1158293 Title: xserver-xorg-video-intel causes xserver to crash To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1158293/+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
