Displays detected but no video output

Hello,

today I've installed first the official displaylink driver using the standalone method and could not get it to work. Then found and installed displaylink-debian. Followed the post-installation guide and it helped to get the displays detected as per instructions (https://github.com/AdnanHodzic/displaylink-debian/issues/228#issuecomment-467889348).

Still, on my current setup, the video output to the display connected to my Lenovo docking station is not working, i.e. the os is not recognising any external displays, after several reboots and attempts.

What to try next? Cheers.
