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. Since this is potentially a new issue/regression, do we need a new ticket? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1752165 Title: TB16 dock freezes X on hotplug when used with external displays To manage notifications about this bug go to: https://bugs.launchpad.net/dell-sputnik/+bug/1752165/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
