Connecting a monitor to the docking station crashes the system

indivisualist · 2016-03-16 20:45:24

Hey guys,

I've got a new ThinkPad T460s plus a new ThinkPad Ultra Dock. On Windows 10, everything regarding the dock works fine - on Linux, there are some issues, including not being able to use an external monitor at it.
When I connect an external monitor directly to the laptop via Mini DP, it works as intended. Connecting the same monitor to a DVI or DP port at the dock leads to a frozen system. The problem is reproducable.

Here are two exemplary traces when I plugged in the monitor and the system froze:

I'm running a fresh Arch Linux:

Linux T460s 4.4.5-1-ARCH #1 SMP PREEMPT Thu Mar 10 07:38:19 CET 2016 x86_64 GNU/Linux

Any ideas on how to proceed from here?

Please use code tags, rather than quote tags, when pasting terminal output. Thanks.

Whoops, my mistake - I just fixed the post. Thanks!

Hi indivisualist,
try to upgrade to linux-4.5 from [testing]. I had all kinds of problems with my integrated HD5500 graphics on v4.4, including crashes when connecting external display. Most of them are gone since the upgrade.
