Hello World!, Hope you're doing well, my name is Samu, I'm a CS student beginner as Linux user, I've tried manjaro and mainly in WSL Ubuntu and Debian, so beforehand let me excuse myself if this post is not helpful to look into my problem.
Alright, so I've been trying to get DisplayLink to work multiple times in the versions of Garuda Dragonized and Dragonized Gaming with no success whatsoever.
On my last attempt (Done in the Garuda Dragonized ed Downloaded and flashed with Garuda Downloader) i think I've narrow the trouble down to the Evdi not showing up as a DRI more on this later.
So i did as follows:
- First did AUR guide on DL (Installed evdi-git since it does support Linux 6.0 Pull 381), all the way up to the installation and stomping with this problem to config it accordingly for Xorg (I don't know if this ver of the distro supports wayland). modesetting doesn't shows up.

- On finding this i made sure, UDLFB module is not present

- Made sure UDL and EVDI where active modules

Does not show evdi as DRI, Here is where I'm in a dead end since i actually don't have a clue where or when does that evdi should show up. It's possible that I'm totally wrong and there's just this small step that i didn't check but pretty much everything that i could search on evdi git, aur or garuda forums was unable to help me move pass this point, please help
