Hi,
I use NixOS 20.03.
XRDP doesnt work as advertised
[https://nixos.wiki/wiki/Remote\_Desktop](https://nixos.wiki/wiki/Remote_Desktop)
Would somone please post a working configuration.nix?
When I specify the ICEW as in the link and log in via RDP, the system just asks for username and password and after that I just get a teal background screen with no buton
I am puzzled that there aren’t many posting about XRDP in NixOS. Do people just use SSH or X window manager and not many people use XRDP? Or do people just use something like the VNCServer?

I just tested it. It works fine here. I am using xorg.
I copy/pasted it straight from the wiki:
```auto
services.xrdp.enable = true;
services.xrdp.defaultWindowManager = "${pkgs.icewm}/bin/icewm";
networking.firewall.allowedTCPPorts = [3389];
```
Here is the full configuration.nix from the VM I use for testing random nixos stuff. It isn’t very clean 🤠

Speaking only for myself, I use ssh 90% of the time. When I need a graphical session I usually use my virtualization platform to get access to the console.

Thank you so much! Let me try soon! Is it the case that I need to turn off the native X session running with the video caed before I can use the XRDP version, maybe? Anyway, let me try!

I don’t think so. I was able to log into the plasma session via the console and rdp concurrently.
That being said, I didn’t test extensively.

@yasu I am using XRDP + remmina (the RDP client) for work extensively. This [module](https://github.com/breakds/nixvital/blob/07c738507e2b5b63b0f4b6fbd386ec7bb25e9134/modules/desktop/remote-desktop.nix) should work for 20.03. Hope it helps. Btw, I am using xfce on remote server, haven’t tested the others yet.

I have just tried again - using the same configuration, I still get the same old problem - just a teal background screen

This XRDP setting is so frustrating. I have no idea what I am doing wrong.
These are the relevant lines from my /etc/nixos/configuration.nix
``
services.xrdp.enable = true;
services.xrdp.defaultWindowManager = “${pkgs.xterm}/bin/xterm”;
networking.firewall.allowedTCPPorts = [3389];
``
Would some please post a complete configuration that does work? (Please make it as “declarative” as possible - no missing dependencies or anything)
I don’t care what kind of Window Manger - just please post something that does work (meaning, I can launch programs)
I am so curious why this takes such an effort. Doesn’t almost everybody who runs graphical applications from a remote terminal use XRDP? Or do people use other methods like VNC?

I’ve been using x11vnc which does work but crashes frequently for unknown reasons. x11 forwarding on ssh works with good stability however

It appears that the following is necessary to make it work.
1. There can only be a **single** desktopManager. Add multiple lines and XRDP won’t work
```auto
services.xserver.desktopManager.gnome3.enable = true;
```
1. Even if only a single desktopManager is specified as above, only **ICEWM** would work. No other desktopManager will work (other than the default xterm).
```auto
services.xrdp.defaultWindowManager = "${pkgs.icewm}/bin/icewm";
```
In the github link below, anything that includes:
```auto
config.services.xserver.displayManager.session.script
```
will fail, because the daisy chaining by “.” (dot) will fail in the middle of the expression.
The expression fails because one of the elements joined by “.” is a list of 2 elements, instead of a single set.

A working solution for KDE has been found ([xrdp server missing KDE option · Issue #57717 · NixOS/nixpkgs · GitHub](https://github.com/NixOS/nixpkgs/issues/57717#issuecomment-698297970)):
```auto
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";
networking.firewall.allowedTCPPorts = [3389];
```
Make sure to reboot after rebuilding.

Thank you:smile: - I have recently switched to GNU Guix but I still use NixOS o my wife’s machine. This is good to know! 😄

I tried that solution. I got the x11 login windows, I saw plasma starting/loading but then I just got a black screen. I’m using Nixos Unstable.
Any idea why it’s not working anymore?
Figured it out: I first needed to log out on the remove machine before connecting with RDP.

I’m trying to use gnome, can you give me the link to the wiki where these lines of code are.
```auto
services.xrdp.enable = true;
services.xrdp.defaultWindowManager = "${pkgs.icewm}/bin/icewm";
networking.firewall.allowedTCPPorts = [3389];

That was over two years ago. It has probably changed quite a bit since then. This is probably the section you want:

Thanks for responding. We got it working. 😀
