The latest package 1.14.03 is actually 1.13. Real v1.14 was unusable on zen kernel.

@olof, fixed the symbolic link bug.

The official evdi is already containing the patch for 6.6 so evdi-git package from AUR is now working.

1) Download the PKGBUILD for Linux 6.6 at: https://gist.github.com/djallits/e727fff8647b9dedca1c62a91588c60a

2) Run makepkg -si in the directory that you downloaded PKGBUILD to.

A patched EVDI exists at: https://github.com/djallits/evdi-edge

@mvidaldp - Yup, I apologize. I think I glanced down and saw @danielkrajnik line of code and mistook it as yours.

@djallits As I specified, I built it against kernel 6.1 (not greater than 6.6). I always stay on the last LTS kernel.

Thank you for explaining @djallits and for the link. Hopefully DisplayLink maintainers will marge it soon.

@segaja This PR looks like it resolves your issue: https://github.com/DisplayLink/evdi/pull/436

@mvidaldp Trying to understand how you were able to build EVDI on a kernel greater than 6.6

@danielkrajnik Because EVDI failed to build. See the PR I referenced to Segaia.

upgrade broke displaylink for me: journalctl -u displaylink.service -ef:

modprobe: FATAL: Module evdi not found in directory /lib/modules/6.6.1-arch1-1

I've had to sudo downgrade linux linux-headers to 6.5.9-arch2-1 to get it to work again.

I can't confirm mvidaldp statement. I got the same error messages mentioned by Segaja. Broken with new kernel 6.6.1. Only works again after downgrading linux(-headers) to 6.5.9

I can confirm at this point (evdi 1.14.1-0) it works with displaylink 5.8-0 and linux kernel 6.1. So no need of evdi-compat-git right now.

This package seems to be uncompatible with the 6.6.1 kernel. When trying to install the dkms module I get this output:

(3/3) Install DKMS modules

The last lines of the mentioned log:

This breaks my entire DisplayLink setup and I don't have all screens available.
