Lenovo ThinkPad Docking Gen 2 not working second monitor

Hello everyone.

I have a ThinkPad T490 attached to a Thinkpad Docking station. On the docking there are two 1080p monitors attached. The problem is that only one of them works. If I go on display settings the second monitor appears connected and inactive, if I turn it on nothing happens.

Also, when I boot my laptop connected to the docking station, after the boot logo I get a black screen. If I unattach the usb-c docking cable then the KDE Plasma loading screen appears and it takes me to login screen. I have to do this every time otherwise it just stays on a black screen.

I tried reboot, attach and flip the cable. Nothing. Also tried install the display link drivers. Nothing.

I’m swithing from Linux Mint, on there never had problem. Tested also on Ubuntu, no problems, also on Kubuntu no problems.
