[Bug 1752165] Re: TB16 dock freezes X on hotplug when used with external displays
Thanks for tipping me off. Support for 5.x kernels was added in 390.>=116 (legacy branch) and the 418.>=43 (bleeding edge) drivers, but not to the current stable or any other branch, so it was failing for me. Mainline 5.0.8 with 418.56 also works fine, so it's "just" the LTS kernel branches that have the bug.

Updating to 5.0.x does not fix it; it disables the nvidia driver because that kernel version is not supported in non-bleeding edge drivers yet.

Started seeing this again on nvidia-396.54 with 4.18.0-16 and 4.18.0-17, possibly 4.18.0-15 - I don't recall having hot-plugged it on -15. It's worse now as the system never recovers any of the displays after hot-plugging and even after removing the dock following a hot-plug the built-in laptop display remains blank. There is no error spam in kernel logs either, in fact USB devices seem to recover fine after hot- plugging, just not the monitors. Once I have a chance I will try out kernel 5.0 and see if it's any different.

Latest Ubuntu 16.04, latest BIOS 1.7. If - it can be of any help, I can get this tested on an XPS 9560 (GTX 1050) - too. + Precision 5520 with Quadro GPU.

If it can be of any help, I can get this tested on an XPS + 9560 (GTX 1050) too. Steps to reproduce: - 1. Plug in monitors into DP and miniDP on the dock. In my case, DP-to-DVI cables are used, but I doubt that it matters. 2. Ubuntu 16.04 GNOME + nVidia drivers with PRIME. 3. Select nVidia GPU in PRIME settings, reboot if needed. 4. Either boot with the dock connected or connect it after booting into user session. 5. Set up monitors if necessary. At this point everything should be working fine. 6. Disconnect the dock, give it a moment to adjust to the new window layout etc. 7. Re-connect the dock. Within a few seconds laptop screen should freeze and external monitors should remain blank, as if not connected. 8. Disconnect the dock. Within a few seconds laptop screen should unfreeze.
