sddm Wayland resolution problem on multiple screen with different resolution

miyoku157 commented 8 months ago

Describe the bug

On my Nixos configuration, I tried to enable the option Services.xserver.displayManager.Sddm.wayland.enable=true I'm using plasma 6 and hyprland which are both Wayland. I've two monitor , one 1920x1080@60 and one 2560x1440@144. And when Wayland Is enable I have a cropped sddm which doesn't allow me to choose my desktop. I tried to disconnect one of the screen by executing a script which turn of one screen thanks to xrandr and the option: Services.xserver.displayManager.setupCommands But the problem is still here (but one of my screen is correctly disconnected) The only way to fix it was to set Wayland to false and use X again

Expected behavior

Sddm printed correctly on both screen and getting access to the list of desktop manager

Temporary solution until #295839 is merged:

services.xserver.displayManager.sddm = {
  enable = true;

  wayland = {
    enable = true;
    compositorCommand = "${lib.getExe' pkgs.kdePackages.kwin "kwin_wayland"} --drm --no-lockscreen --no-global-shortcuts --locale1";
  };

  extraPackages = with pkgs; [
    kdePackages.layer-shell-qt
  ];

  settings = {
    General = {
      GreeterEnvironment = lib.concatStringsSep "," [
        "QT_WAYLAND_SHELL_INTEGRATION=layer-shell"
      ];
    };

    Theme = {
      # Both of these are nessecary otherwise the cursor isn't shown at all
      CursorTheme = "breeze_cursors";
      CursorSize = 24;
    };
  };
};

You probably also want to copy the display config using the manual method described on archwiki.

Is this still an issue with kwin_wayland?

miyoku157 commented 8 months ago

Hi, i try again today and it's still not working for me. I upgraded my flake to use kwin to test, kwin work but i can't figured how to customize the background or setup. Even through theme like "breeze" for example Even though the problem is still present if i use Weston Also, another thing i've noticed (But maybe unrelated) is that the config: autoNumlock=true; Doesn't work anymore, at boot it's never ON.

I have the numlock problem too.

For the purpose of this issue - with kwin, the resolution problem has been fixed, is that correct?

miyoku157 commented 8 months ago

Yes, Kwin allow me to get both screen at good resolution and manage my display. (But it's not as fancy as weston but it's another problem ^^)
