Failed to Connect to Wayland Display

[Scruffy]

@sdetweil

I ran the first command and this is the output:

~ $ ps -ef | grep -v grep | grep -i -e xway -e labwc
ferguson   66504       1  0 15:32 ?        00:00:01 /usr/bin/Xwayland -auth /home/ferguson/.Xauthority :0 -rootless -core -terminate 10 -listenfd 28 -listenfd 29 -displayfd 88 -wm 82

When I run the last commands, it’s still not launching. The MM screen flickers up for a second and then goes away. This isn’t unique to the above steps.

Logs look similar, if not the same:

Strange indeed.

@Scruffy ok, try

npm run start:wayland

@sdetweil said:

npm run start:wayland

Unfortunately, still no go.

The whole system is feeling sluggish… I wounder if it’s an SD issue…?

I have a new SD card arriving later today. I’ll image and reinstall MM and report back.

If it’s still not working, I’ll provide the logs again.

Cannot thank you enough, @sdetweil. You’re incredibly responsive and your support is greatly appreciated.

Cheers!

@Scruffy use my backup/restore scripts to save and restore your MagicMirror config and modules list

https://github.com/sdetweil/MagicMirror-backup-restore
Backup, copy off backup folder, tiny size

Install new MagicMirror and copy back folder and restore

@Scruffy I actually never resolved my issue either. But, my system was very sluggish as well.

[sdetweil]

@atwist the latest PI OS is larger than the previous versions…

leading to more swapping. This can affect performance because of the speed of the SD card.

free -m

will tell you how much memory and swap space you are using.

[Scruffy]

@atwist what did you end up doing? Or are you still without MM working?

[Scruffy]

@sdetweil I ran the command and this is my output.

             total       used      free      shared     buff/cache   available
Mem:         3992        2153      210       550        2126         1839
Swap:        511         30        481

Is the output in MB? Doesn’t seem like it’s to the point where everything is so slow to respond.

@Scruffy pi4, 4 gig?
