Raúl Sánchez Siles has a good lead on this in the fd.o bug 11432, https://bugs.freedesktop.org/show_bug.cgi?id=11432
He's working around the crash by forcing PipeA to be enabled, without an external screen attached. This is a step in the right direction to debugging the issue. We may be able to get a better solution still by identifying where this specific crash occurs, and either enabling PIpeA for that portion of code, or avoiding that code-path when PipeA is disabled. -- xserver-xorg-video-intel hangs the system when laptop lid is closed https://bugs.launchpad.net/bugs/138256 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
