Note as of [https://github.com/NixOS/nixpkgs/pull/351752 2024-10-30] nixos-unstable sway uses <code>wlroots_0_18</code>. The patch above applies correctly but you will need to invoke sway with the <code>--unsupported-gpu</code> flag.

Note as of [https://github.com/NixOS/nixpkgs/pull/351752 2024-10-30] nixos-unstable sway uses <code>wlroots_0_18</code> and as of NixOS 25.11 sway uses <code>wlroots_0_19</code>. The patch above applies correctly but you will need to invoke sway with the <code>--unsupported-gpu</code> flag.

For NixOS 25.11 and later you also will not have to add a dependency on the dlm service but instead use <code>displaylink-server</code> like KDE Plasma.

You can also test if your setup is working without this service (you will still require the patch for wlroots and sway with the <code>--unsupported-gpu</code> flag) by invoking the DisplayLinkManager executable (provided by the displaylink package) as root. If the setup is working, sway should at this point recognize the new display(s).
