@Robert @Giacomo Are Linux kernel 4.4.0-73 ~ 4.4.0-77 all failed to work? Can you paste the output of `lsmod | grep i915` here? Also, which docking station do you use? I have an USB type-C docking station (TB15) at my hand, but I am not sure if you use this one...
@Robert I am not sure which driver Broadwell uses, i915 or i915_bpo. Do you use the port on the Docking station? Does this happen on laptop's port? @Giacomo IIUC "drm/dp/mst: fix kernel oops when turning off secondary monitor" only silence the annoying kernel trace, it does not bring any functional change. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1686189 Title: External monitor connecting problem on Intel graphics card To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1686189/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
