Public bug reported: Ubuntu 18.04 (linux-image-4.18.0-16-generic) ThinkPad 460P Intel i7-6700HQ Nvidia GTX940MX (nvidia 415 drivers)
When using with dock, attached monitor is not detected, laptop monitor remains blank. Laptop freezes until I detach it from the UltraDock again. Requires a reboot with the UltraDock attached to make it working. It worked in the past since 4.18 with the Laptop booted with the UltraDock and detach ad attach the laptop again. This time I detached the Laptop, worked a few days without the UltraDock (used Standby over night) and tried to attach it again. Maybe it happens because I use HWE now. But the errors in dmesg and logcat are looking like my bugreport for kernel 4.15 where the UltraDock didn't worked. https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1781904 --- ProblemType: Bug ApportVersion: 2.20.9-0ubuntu7.6 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: martin 17549 F.... pulseaudio /dev/snd/pcmC0D0p: martin 17549 F...m pulseaudio CurrentDesktop: X-Cinnamon DistroRelease: Linux Mint 19.1 HibernationDevice: RESUME=UUID=4a747812-cab0-438b-ace1-a46b73f00d4a InstallationDate: Installed on 2018-07-21 (236 days ago) InstallationMedia: Linux Mint 19 "Tara" - Release amd64 20180626 Lsusb: Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 008: ID 058f:9540 Alcor Micro Corp.
