Failed to Connect to Wayland Display

atwist

I upgraded my MagicMirror and now the logs are showing the below errors:

ERROR:ui/ozone/platform/wayland/host/wayland_connection.cc:202] Failed to connect to Wayland display: No such file or directory (2)
ERROR:ui/ozone/platform/wayland/ozone_playform_wayland.cc:202] Failed to initalize Wayland platform
ERROR:ui/aura/env.cc:257] the platform failed to initalize. Exiting.

How do i resolve this?

@atwist how does MM get started?

using pm2?

if so, find the startup command

pm2 status
pm2 info xxxx
where xxxx is the name or number on the row of the app you want info about

you need the value next to
script path

then examine that file…

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
