17.10 Problems brainstorm

[Wunsz]

The dmesg output with error is when disconnect happens.

My setup is:
Samsung FHD display via HDMI
Dell FHD display via DisplayPort
Lenovo USB mouse
Lenovo USB keyboard
Phillips headphones via 3.5mm jack (no microphone)


Here is my output (with one DisplayPort monitor attached)
