Buongiorno. Qualcuno di voi e' riuscito a usare un monitor che ha bisogno dei driver DisplayLink su NixOS?

Io ho seguito questa guida ma ancora non riesco a far funzionare il mio monitor portatile AOC E1759FWU.
https://wiki.nixos.org/wiki/Displaylink

Sono su X11 e come desktop environment uso XFCE, e come display manager uso LightDM.

Nella guida mi sembra di aver capito che serve una configurazione particolare per il systemd service displaylink-server SOLO nel caso in cui uno usi KDE Plasma.

La mia configurazione attuale e' in questo NixOS module.
https://github.com/jackdbd/nix-config/blob/main/nixos/modules/displaylink/default.nix

nixos-rebuild switch --flake .#<host> --target-host <user>@<IP> --use-remote-sudo

  services.openssh = {
    enable = true;
    settings = {
      PermitRootLogin = "no";
      PasswordAuthentication = false;
      PubkeyAuthentication = true;
      MaxAuthTries = 3;
      ClientAliveInterval = 300;
      ClientAliveCountMax = 2;
    };
    allowSFTP = false;
  };
