Chris, I don't want to bother you but I have to insist: with the UXA accelmethod the problem does not occurs. I created the file /etc/X11/xorg.conf.d/20-intel.conf instead of using the old xorg.conf and my notebook now works fine on both 13.04 (kernel 3.8.x) and 13.10 (3.10.x).
Don't you think it is appropriate to consider this solution as a clue to this issue? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1186800 Title: [830 v3.7 regression] Video goes blank and system hangs (using an old kernel fix it) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1186800/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
