I am trying to configure my new Thinkpad with Ubuntu 22.04.2 LTS (Desktop) and connecting it via Docking-Station (USB-C connector) to an external monitor (see details below). I tried different suggestions (like installing additional DisplayLink drivers) but did not suceed.
I then tried the most recent desktop version (23.04) and the external monitor worked out-of-the-box (but not usb-mouse and network via docking-station).
Then I tried Ubuntu 20.04.6 LTS Desktop and everything worked (monitor, mouse, network).
So currently I would have to install 20.04 as my Desktop and stick to it at least until the next LTS is released as I do emphasize stability in my setup :)
Is there some trick to get 22.04 working after all?
thx
