xrdp server missing KDE option

Zhen-hao commented 5 years ago

When I log on to remote NixOS via Microsoft Remote Desktop, I get xterm instead of KDE desktop though Plasma 5 is installed on the server.

Steps to reproduce

I used the setting found on https://nixos.wiki/wiki/Remote_Desktop.

Technical details

Please run nix-shell -p nix-info --run "nix-info -m" and paste the results.

I run to the same problem. Maybe someone can help us out? It doesn't matter what I do, it always defaults to xterm, while I use KDE on the computer I want to take over with it.

I added the following:

services.xrdp.enable = true;
networking.firewall.allowedTCPPorts = [ 3389 ];

And tried lots of different ways of writing kde/startkde/plasma5 etc. in the following line: services.xrdp.defaultWindowManager = "${pkgs.plasma5}";

In https://github.com/NixOS/nixpkgs/blob/master/nixos/modules/services/networking/xrdp.nix it says that you could also use ~/startwm.sh, so I added that (with execution permission) with different stuff in it, but also to no avail.

Can anyone figure out what I (and @Zhen-hao) are doing wrong?

Except for icewm, none of above suggestions work

I noticed that i had to reboot to get xrdp working.

It works with xfce and icewm on stable.

davidak commented 4 years ago

When setting something like this

services.xrdp.defaultWindowManager = "${config.services.xserver.displayManager.session.script} pantheon+none";

rebuild fails with

error: value is a list while a set was expected, at /root/nixos/machines/zipper/configuration.nix:46:43

even on unstable. but that setting should be a string, as it is. the error makes no sense

same with the mentioned examples like

services.xrdp.defaultWindowManager = "${config.services.xserver.displayManager.session.script} mate+none";

I get the same error. I can only get icewm to work.

A few days ago, I decided to switch to Guix - it will take a while but I will see if this issue is any better in the Guix world :-)

I managed to get KDE+xrdp working! I have it working on NixOS on AWS. Here is my configuration.nix:

{ config, pkgs, ... }:
{
  imports = [ <nixpkgs/nixos/modules/virtualisation/amazon-image.nix> ];
  ec2.hvm = true;
  time.timeZone = "Pacific/Auckland";
   users.users.daniel = {
     isNormalUser = true;
     extraGroups = [ "wheel" ]; # Enable ‘sudo’ for the user.
   };

  environment.systemPackages = with pkgs; [
      plasma-desktop
      sddm
  ];

  services.udisks2.enable = pkgs.lib.mkForce true; # Necessary to override this from amazon-image.nix because it is set to true as a part of KDE
  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 ];

}

This and this turned out to be the most useful while figuring this out.

Note: weirdly, when "share clipboard" is on (using Microsoft Remote Desktop on MacOS) it fails to connect successfully.

@Coda-Coda fantastic, I can verify this works on 20.09! Make sure to reboot after rebuilding before trying.

@tbenst thanks, just wondering - does "share clipboard" work for you?

tbenst commented 4 years ago

Yes it’s working for me

i wanted to run gnome when i login locally, and plasma for xrdp, needed this tweek:

#  services.xserver.displayManager.sddm.enable = true;
services.xserver.displayManager.gdm.enable = true;
services.xserver.desktopManager.plasma5.enable = true;
programs.ssh.askPassword = lib.mkForce "${pkgs.plasma5Packages.ksshaskpass.out}/bin/ksshaskpass";

chose the plasma askpass based on this comment on nixOS forums

NixOS / nixpkgs
