Trouble configuring displaylink with Dell D6000 dock

Hi, newbie here.
So far I've been able to follow the wiki and forum posts to set up Arch on my new laptop, but this one has me stumped.

My machine is a Thinkpad X1 Carbon gen11 (intel iris graphics) running Linux 6.1.55-1-lts x86_64 using GNOME

I have a Dell D6000 that has two DP monitors and one HDMI monitor plugged in.
I'm trying to set up this dock so that I can use the mouse and keyboard, ethernet and three monitors that are all plugged in.
Ethernet, mouse and keyboard work, but monitors do not.

I've followed the instructions found at https://wiki.archlinux.org/title/DisplayLink
1. installed evdi-git
2. installed displaylink and enbled service
3. created 20-evdi.conf file in xorg.conf.d with the recommended settings
4. reboot

Now sometimes when I boot or take reconnect the usb-c cable the HDMI monitor will work (the two DP monitors have never worked), usually it does not.
xrandr --listproviders only shows 1 provider named "modesetting", so this is where I cannot follow the wiki page anymore.

Providers: number : 1
Provider 0: id: 0x48 cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 4 outputs: 6 associated providers: 0 name:modesetting

I expected there to be another provider maybe named "intel"?

Hoping someone has the knowledge to help me figure this out!

Is xf86-video-intel installed ? If yes, remove it.

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

clean chroot building not flexible enough ?
Try clean chroot manager by graysky

I briefly had that installed but removed it while debugging, it's not installed now.

Post xorg log please. see https://wiki.archlinux.org/title/Xorg#General for info where to look for it.

Welcome to archlinux forums (didn't realise these are your first posts).

Thanks!

I actually just came across this conveniently new post on reddit of someone dealing with the same issue as me:
https://old.reddit.com/r/archlinux/comm … e_which_i/

I followed his suggestion of using evdi-compat-git for evdi and replacing some settings to prevent the docking station from trying to do power usage optimizations.
After rebooting I'm seeing three providers

Providers: number : 3
Provider 0: id: 0x48 cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 4 outputs: 6 associated providers: 2 name:modesetting
Provider 1: id: 0x14f cap: 0x2, Sink Output crtcs: 1 outputs: 1 associated providers: 1 name:modesetting
Provider 2: id: 0x12c cap: 0x2, Sink Output crtcs: 1 outputs: 1 associated providers: 1 name:modesetting

All monitors connected to the docking station are working as expected now.
So I guess it was a simple compatibility issue between evdi and my kernel that was somehow fixed by evdi-compat-git?

Happy it works now, thanks for assisting!
