Failed to Connect to Wayland Display

atwist

Yes, pm2.

Here is that file.

#!/bin/bash

This file is still here to keep PM2 working on older installations.

cd ~/MagicMirror
DISPLAY=:0 npm start

sdetweil

@atwist yes, that is the file, should have started in default mode

there is an updated version

can you replace all the lines of text there with this

#!/bin/bash
cd ~/MagicMirror

if [ $(ps -ef | grep -v grep | grep -i -e xway -e labwc | wc -l) -ne 0 ]; then 
   # if WAYLAND_DISPLAYis set, use it, else set to -0
   export WAYLAND_DISPLAY=${WAYLAND_DISPLAY:=wayland-0}
   npm run start:wayland
else
   DISPLAY=:0 npm start
fi

atwist

I updated that file but the error still exists.

@atwist interesting

can you do this

cd ~/MagicMirror
npm start

atwist

Yes, that starts everything and gets me running like normal. Thanks!

So how do I get it to run on reboot moving forward?

sdetweil

@atwist weird… all the script does is the same thing…

can you show me the part of the output from npm start like from my desktop
