DisplayLink Forum - View Single Post - Ubuntu 20.04 - Displays Not Working After Unplugging Dock

Hello,

I am on Ubuntu 20.04, kernel 5.11.0-27 and using version 5.4 of the Display Link driver and EVDI 1.9.1. The first time I plug in the dock both of my monitors appear and everything works fine. A problem arises if I unplug (for example to use another computer with the dock) and then try to plug back in to the Ubuntu machine - nothing, blank screens. A restart fixes this.

I also unable to properly shut down the PC if using DisplayLink, the monitors go blank, but the fans and LEDs remain on, having to be turned off by holding the power button.

It always worked fine in the past, I could unplug the dock and plug it back in later, so I suspect it's a conflict with the kernel and driver versions, but does anyone have any ideas to sort it?
