Michal,
I have just joined this forum as I have the same problem since yesterday. tried the displayport and dvi port of the Lenovo dock. Running Ubuntu 14.04.5, a hardware update recently when I restarted the display on the monitor was gone.
Tried uninstalling and re-installing the driver already. Got the Display link support too mentioned in this thread. Is there any chance you could tell what is going on. Thanks
