Exclamation Frequent GPU Hangs and Xorg crashes (Ubuntu 20.04 Kernel 5.8)

Dear all,

I am using a DisplayLink dock station with an external monitor, connected to my DELL latitude laptop running Ubuntu 20.04.

The external display works fine at first, but frequent freezes happen, resulting from a Xorg crash and a "GPU hang" (according to dmesg output). When this happens, all graphics are unresponsive, even though I can still see my mouse pointer move. As a result, I have to log into a tty session in order to restart my display manager, thus losing all my opened graphical applications.

This happens most frequently when the computer is doing (reasonably) intense work, such as a system backup or a zoom conference call.

Is this kind of problem known for my Ubuntu version? Is there a fix?
You will find attached a debug output from DLSupportTool, ran right after such a freeze.

Thanks a lot for your help
