Hi, all.
I have a Lenovo ThinkPad 40AF docking station (Hybrid USB-C with USB-A dock).
I have a total of 4 monitors:
Monitor 1 is integrated within the lid of my laptop.
Monitor 2 is connected to a HDMI-port directly on my laptop.
Monitor 3 is connected to a HDMI-port on the docking station.
Monitor 4 is connected to a DisplayPort on the docking station.
In Linux Mint, I do get all 4 monitors working by downloading and installing (the apt/deb package of) the proprietary drivers published by Synaptics. (Although this does not work entirely flawlessly. With that driver, I have to disconnect the docking station from the computer by pulling the cable before booting, otherwise the system gets stuck and never finishes the boot process. Only after the display manager has been successfully loaded, I may safely connect the docking station without issues.)
In Arch Linux, after a clean install, monitor 1 and 2 is working out of the box. To get monitor 3 and 4 to work, I assume that I need to install corresponding drivers for Arch. This article seems to explain what to do. However:
I am not sure whether I should follow the instructions for USB 2.0 DL-1x5, DL-1x0 Devices or the instructions for USB 3.0 DL-6xxx, DL-5xxx, DL-41xx, DL-3xxx Devices.
If the USB 3.0 instruction should be followed, I am not sure whether I should install the evdi-git package or the evdi-compat-git package.
How do I determine which instructions to follow? Any advice, anyone?

The descripton of the evdi-compat-git(AUR) packages states:
kernel module for DisplayLink driver, aimed at compatibility with DisplayLink package and Official kernels
The descripton of the evdi-git(AUR) package states:
kernel module that enables management of multiple screens, primarily for DisplayLink USB VGA DVI HDMI DisplayPort video
The descripton of the evdi(AUR) package states:
A Linux® kernel module that enables management of multiple screens.
On a general basis, it seems that the package evdi-compat-git(AUR) is the preferrable one for DisplayLink hardware.
I am still not sure what approach I should have used to determine which instructions to follow, based on the specific hardware that I have. However, with a bit of trial and error, I got the hardware to work. So I am changing the state of this post to [SOLVED].
This is what I did to make it work:
First attempt:
sudo aura -Syu # Success!
sudo aura -Ayu # Success!
sudo aura -A evdi-compat-git # Error!First attempt failed, with the following output:
bash: pkg-config: command not foundI fixed this by installing the package pkgconf:
sudo aura -S pkgconf # Success!Second attempt:
sudo aura -A evdi-compat-git # Success!
sudo aura -A displaylink # Success!
sudo systemctl start displaylink # Monitor 3 and 4 woke up. Working perfectly!
sudo systemctl enable displaylink # Success! Second attempt successfully completed.
Also worth mentioning:
I am running Gnome DE with Wayland support. Thus, no need to configure xrandr and /etc/X11/xorg.conf.d/20-evdi.conf in my case.
