I think most likely the problem is a side effect of the customizations this machine has experienced over the years. Like switching display managers multiple times, or using a non-standard kernel.

I would suggest the fastest way to a fix might be to just reinstall fresh: http://cdimage.ubuntu.com/daily-live/current/

If you need DisplayLink support for kernel 5.13 then I can confirm the 5.5 beta driver works well: https://www.synaptics.com/products/displaylink-graphics/downloads/ubuntu
