I see there are other topics but with no answers so I'll try and add a little more detail. This thread has a similar topic though:
Context
Symptoms are present when booting the laptop regardless of being plugged into a Dell D600) dock or not however where plugged in there are multiple reboots required to get the dock to behave and enable the screens and keyboard/mouse. When this boots the system is stable.
Additionally, i'm not sure if this is a red herring or not but i seem to recall this only starting after an upgrade to 22.04 from 20.x. I do see hints online about updating BIOS but it's beyond my confidence at the moment to get going and potentially brick the machine. It's perfect for what I need it for.

Finally, I had to completely blitz the DisplayLink drivers and dkms as it completely killed my machine. It wouldn't boot into the GUI and had to re-install the core files. evdi really screwed something but seems to be stable now.
Output of dkms status:
evdi/1.13.1, 6.2.0-26-generic, x86_64: installed
evdi/1.9.1: added
Thank you so much in advance, while this isn't troubling me too much I'd like it very much to be able to have a clean, error-free boot I enjoyed previously.
