I'm having this issue on both precise and raring on ThinkPad X201. This issue only appears when external display attached to DisplayPort.
The behavior is consistent with stock/mainline kernel with stock or intel linuxgraphics drivers (3.8.0-26-generic, 3.8.0-27-generic, 3.8.0-27-generic with intel linux-graphics 2013Q2, 3.10.0-997-generic,3.10.0-997-generic with intel linux-graphics 2013Q2). External display works perfectly on VGA port. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1182386 Title: intel_display.c:1028 intel_wait_for_pipe_off To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1182386/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
