Title:
[Lenovo Thinkpad T460p] Ultra Dock external displays not detected
after suspend/resume cycle
Status in linux package in Ubuntu:
Invalid
Bug description:
The bug is identical to the expired
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1568573 where a
new report was requested.
This time around with a fresh install of 16.10 amd64 on a Thinkpad
T460p and a Lenovo Ultra Dock with two external monitors.
The setup does work when freshly booting with the laptop on the dock.
Suspending undocked, docking, resuming doesn't light up the external monitors.
Neither does just docking awake.
The relevant error messages seem to be these:
Dec 20 13:21:50 talas kernel: [265391.482117]
[drm:intel_dp_link_training_clock_recovery [i915]] *ERROR* too many voltage
