We have two laptops T470 & T480 with docking stations. Both run Ubuntu 18.
Everything is working ok if the laptop starts while already in the docking station.
But, if I'm trying to dock it while running or while sleeping it never recovers for that the screen freezes.
Only restart will be make it run again.
BTW, many times I see two strange things:
1. Undocking releases it, but only as long as it's not docked.
2. When the screen freezes the only thing the sill work is the mouse which I can move around but I can't really use for anything else.
