I am total new in the world of linux, but I enjoy to work with it from the first second!
So at this point I need your help.
I have got a lenovo Thinkpad E470 Notebook and a Thinkpad Pro Dock USB 3.0 (40A7). Every thing works fine, excepting the display. It seems if the additional Display is not found while using it through the dock. If i connect it directly to my laptop via HDMI everything works fine!
Maybe you have some ideas for me!?
A small summary of the setup follows:
Dock and Laptop are connected via USB 3.0.
The output-port of the dock is an DVI Port, and is directly connected to the secondary display.
