Tiger VNC

Nixpkgs has a package but no service. The server component can be started using the vncserver command. To connect use the vncviewer command.

x2go

X2go client is packaged in nixos as x2goclient.

The server is installed by putting the following line:
services.x2goserver.enable = true;
to /etc/nixos/configuration.nix.

RDP

NixOS has first class support for XRDP server.

services.xserver.enable = true;
services.xserver.displayManager.sddm.enable = true;
services.xserver.desktopManager.plasma5.enable = true;

services.xrdp.enable = true;
services.xrdp.defaultWindowManager = "startplasma-x11";
services.xrdp.openFirewall = true;
