Then the main issue: freezes.

Do I understand correctly, that so far the freezes have only happened when you have had two monitors attached to the DisplayLink dock? Never with just one monitor?

Which DisplayLink dock do you have?

You said changing the display configuration is a sure way to freeze? What do you do exactly, something in GNOME display settings or plugging cables or?

I doubt the HDMI vs. DVI or monitor brand/model would have an effect here, so I think you can leave testing those details for later.

For now, I would like us to concentrate on Ubuntu 19.10, and the full DisplayLink driver package 5.2.14 which includes the EVDI kernel module and libevdi0.

Verify what version of libmutter-5-0 package you have installed exactly. If it's older than the one mentioned here to contain the fix I thought would help, try to get that updated. Let me know what version you have, I can have a go at reproducing the freeze.

When your machine freezes, can you access it from a remote, e.g. via ssh?

If you can, you could first take a look at the process list: are gnome-shell and DisplayLinkManager running? Do they consume CPU?

The next step would be installing a bunch of dbgsym packages and attaching GDB to gnome-shell when it's frozen to see where it is at. Do you know how to do that?
