Screen error detected: wlr-randr command error (mode 3)

[htilburgs]

Using v2.0.0 for several weeks now (first tested with DEV and now with the official release) without problems. Suddenly I get an error on my MagicMirror, everytime it wakes up:

Screen error detected: wlr-randr command error (mode 3)

I don't know what changed that causes this. If you need more info, please ask.

CONFIG.JS

                        module: 'MMM-Pir',

In the startup Log I see

In the MagicMirror error log I see following

[ERROR] [MMM-Pir] [LIB] [SCREEN] wlr-randr: Error: Command failed: WAYLAND_DISPLAY=wayland-0 wlr-randr | grep 'Enabled'
failed to connect to display

Strange thing is that in my config.js file I have put wrandrDisplayName: "wayland-1"

[htilburgs]

I've been testing and when I manualy change MMM-Pir.js "waylandDisplayName: "wayland-0" into "waylandDisplayName: "wayland-1" the error disappears and everything works fine. Maybe you can check this out.....

Module.register("MMM-Pir", {
  requiresVersion: "2.28.0",
  defaults: {
    debug: false,
    Display: {
      animate: true,
      colorFrom: "#FF0000",
      colorTo: "#00FF00",
      timeout: 2 * 60 * 1000,
      mode: 1,
      counter: true,
      style: 1,
      lastPresence: true,
      lastPresenceTimeFormat: "LL H:mm",
      availability: true,
      autoDimmer: false,
      xrandrForceRotation: "normal",
      wrandrForceRotation: "normal",
      wrandrForceMode: null,
      waylandDisplayName: "wayland-0"
    },

since v2.2.0 there is a change in config see there

You can disvover that wrandrDisplayName feature is renamed to waylandDisplayName

So, that was hard to see! Thank you, all works again.
