EVDI compilation error in Ubuntu 18.04 w/ kernel 5.4.0-84

[gc51]

Hi all,
I am trying to install the drivers for Ubuntu 18.04 with Kernel 5.4.0-84.

I tried with DisplayLink driver 5.4.1 (listed as ubuntu 20.04). It installs, but then Xorg enters a login loop, so it doesn't work (wayland logs in but the screen doesn't work either).

So then I tried to install the latest one for 18.04, which is DisplayLink driver 5.2.14 and it shows an error:
Verifying archive integrity... 100% All good.
Uncompressing DisplayLink Linux Driver 5.2.14 100%
DisplayLink Linux Software 5.2.14 install script called: install
Distribution discovered: Ubuntu 18.04.6 LTS

ERROR (code 3): Failed to build evdi/5.2.14. Consult /var/lib/dkms/evdi/5.2.14/build/make.log for details..


From here: https://github.com/DisplayLink/evdi/issues/215 I found it may be an issue with the kernel and evdi, but I am not sure how to install evdi and displaylink separately (nor if that would work), if that was to work. Anyone else working on Ubuntu 18.04 who may lend a hand?

After checking a bit I think this may be caused by the propertary nvidia drivers. I am pretty sure I was using displaylink before with nvidia drivers in the past, but I guess something ahs changed since?

Anyone has used nvidia drivers and displaylink correctly?
