I have created an upstream bug report: https://bugs.freedesktop.org/show_bug.cgi?id=94250
The patches mentioned in the bugreport fix the problem for me. Can the Xenial version of the driver be updated, or the patches be backported? ** Bug watch added: freedesktop.org Bugzilla #94250 https://bugs.freedesktop.org/show_bug.cgi?id=94250 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1540953 Title: Xorg crashed when undocking Lenovo T450s from docking station To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1540953/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
