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;

Notice: You need to log out the user first on the remote machine, otherwise you'll get a black screen. (Source: Reddit ). It may be particularly true on a multi-user system. You may be able to work around this by enabling and configuring Polkit. The configuration for enabling these permissions is the example code on that page.

freerdp or remmina can be used on the client side.

Guacamole
