Title:
linux-image-4.18.0-16-generic breaks Lenovo T460P on Ultradock
Status in linux package in Ubuntu:
Confirmed
Bug description:
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.
