trying to get my multi-display working using displaylink, evdi on the latest kernel. Evdi wont build a 1.12 version anymore, was using evdi-git, but tried evdi as well. Anyone have a known workaround other than rolling back? The build barfs with:

Are you using the AUR package?

https://aur.archlinux.org/packages/evdi

It doesn’t look like there is support for kernel 6.2 yet.

You might switch to the lts kernel until it is added.

4

Yeah - I had it working up until this latest kernel (I think it worked on 6.2.1) using the evdi-git package. But it is now out of date as well.

5

Yes. The support hasn’t been merged into evdi yet so I don’t think any package will help you.
