Ubuntu 18.04.2 LTS with A 5.1.9 KERNEL

[emilie]

Hello,
I am running Ubuntu 18 with an updated kernel 5.1.9
(I had to use a new kernel because sound wasn't supported on the regular LTS kernel which is 4.18 I think)

The problem now is that I don't manage to install DisplayLink driver on my device.
When I try to do so:

sudo ./displaylink-driver-5.1.26.run
Verifying archive integrity... 100% All good.

I did ./displaylink-driver-5.1.26.run --noexec --keep

and also cloned and compiled https://github.com/DisplayLink/evdi devel branch
now I have made evdi_lib.o and libevdi.so
I just don't know how to proceed to finish installing (https://support.displaylink.com/know...r-to-other-lin)
please help
