Feature Request: Out-of-the-box DisplayLink support

Summary

Add native DisplayLink support to Omarchy so that DisplayLink devices
work out-of-the-box after a fresh installation, without requiring
manual driver installation and configuration.

Current behavior

After a fresh Omarchy installation, connecting a DisplayLink device
(tested with DisplayLink DL-DOCK6350) does not work. The device is
not detected and no display output is produced.

To make it work, the following manual steps are required:

1. Install the evdi kernel module
2. Install the displaylink driver manually
3. Enable and start the displaylink systemd service
4. Configure ~/.config/hypr/monitors.lua with the correct monitor layout

Expected behavior

After a fresh Omarchy installation, connecting a DisplayLink device
should be automatically detected and work with Hyprland/Wayland without
any manual intervention.

Proposed solution

• Include evdi and displaylink as optional dependencies during
  installation, or detect DisplayLink devices and install drivers automatically
• Enable the displaylink systemd service by default when the hardware
  is detected
• Add documentation to the Omarchy manual explaining how to configure
  multi-monitor setups with DisplayLink devices

Environment

• Omarchy version: latest
• Hardware: DisplayLink DL-DOCK6350
• Kernel module: evdi 1.15.0
• DisplayLink Manager: v6.8.1.0

Additional context

DisplayLink is widely used in docking stations and is a common use case
for laptop users. Adding out-of-the-box support would significantly
improve the experience for users coming from macOS or Windows where
DisplayLink works automatically.

+1 — confirming DisplayLink works fine on Omarchy 4.0.3 with the AUR packages, so this should be a small, contained addition.

Setup tested

• Device: Elgato Prompter (USB 17e9:ff1a, DisplayLink), 1024x600 panel
• Omarchy 4.0.3, kernel 7.2.3-arch1-3, Hyprland 0.56.2, AMD GPU, Secure Boot off
• Packages: linux-headers, dkms, evdi-dkms 1.15.0 + displaylink 6.3 (AUR)

Steps that got it working

sudo pacman -S --needed linux-headers dkms
yay -S evdi-dkms displaylink
sudo systemctl enable --now displaylink.service

Hyprland picks it up as DVI-I-1 right away, no env vars or AQ_DRM_DEVICES needed. Survives reboot.

Gotchas worth handling

• displaylink pins evdi<1.16, and evdi is rebuilt via DKMS on every kernel update. That's the fragile part and the main reason I'd keep this opt-in rather than installed by default.
• Small DisplayLink panels inherit the default monitor scale from monitors.lua (1.6 here), which makes a 1024x600 screen nearly unusable. Users need a per-output scale = 1 line.

Proposal
An opt-in installer rather than out-of-the-box:

1. omarchy-hw-displaylink: detects any DisplayLink device via /sys/bus/usb/devices/*/idVendor == 17e9 (no lsusb dependency).
2. omarchy install hardware displaylink: installs the packages above with omarchy-pkg-add and enables displaylink.service, plus a menu entry.
3. Possibly later: have the installer offer it when omarchy-hw-displaylink matches.

Would a PR along these lines be welcome? Happy to open it and would appreciate testers with DisplayLink docks (e.g. DL-6xxx), since I've only verified the Prompter.

Yes! And you can count to me to verify with Display Link docks!
