Alpine Linux support: my progress

[bmentink]

Hi there, great you are attempting this. I am running Alpine Linux on a Macbook M1, and it is my preffered daily driver, so until the official DisplayPort is upstreamed, I would like to use my WavLink adapter as I did on Fedora remix.

What is the latest status on this project?

apk add gcompat

And I created a service to run /etc/sv/displaylink-driver/run at boot time.

However, I don't really know what to do from here... ?

I can see some evdi stuff in my /var/log/Xorg.0.log file

But I can't see how to actually use these cards?

Can someone link me to some instructions of how to make use of the drivers now that they're installed and the display manager runs?

I tried running the display manager with logging and debugging turned on, but it's just spitting out base64-encoded randomness at me....
