I just bought a brand new Thinkpad T14s for about 1700 Euro. It has no Ethernet or Displayport, just USB-C.
So I thought I buy a dock. I bought this one:
Its connected via USB-C, has full Linux support and also my Thinkpad T14s is listed as “works great” with it.
Now the issue:
I run Pop_OS! 20.04.
Yesterday I connected the dock, it worked great. Displayport-Monitor, and all…
I shutdown my Laptop , tried it again and I never got a connection after that. I unplugged everything, tried it 5 times, then Displayport worked again.
This morning… I just cannot get it to work. I checked different Monitors, Cables, all of the 3 graphics connections on the dock.
I am very depressed because even an explicit linux device does not work well. Also… I dont know if the problem is the 80 Euro dock, or the 1700 Euro Notebook. And I dont have very much time to re-send the devices.
Apart from that… the laptop works great. I think its this docking issue.
I know real connections are better… but hey… its also a nice idea to have plugged everything via one little usb-c.
BTW: what usb-c dock do YOU have that work?
I would be very happy if someone could give me advice.
PS: After I wrote this - I had the dock disconnected for 15 minutes - I plugged it in and now displayport works again. You know, I wonder if its a hardware issue… or a lenovo issue… or a linux issue… or a popos issue
