Apologies if the title is an incorrect conclusion.

As using MagicMirrorOs that uses Karsten’s docker build.

Noticed my screen at a tty login prompt instead of displaying my configuration that has been running a couple of weeks.

After investigating a little, I can see the labwc container keeps restarting with the below error messages in the logs.

It looks like it did pull of the latest version of the container ~3 hours ago, and I see that is when a new version of the content was published.

Is there an issue with th*e latest version of the labwc container?
Or any suggestions on troubleshooting?

Some friendly trouble-shooting help
===================================

If a seat could not be created, this may be caused by lack of permission to the
seat, input and video groups. If you are using a systemd setup, try installing
polkit (sometimes called policykit-1). For other setups, search your OS/Distro's
documentation on how to use seatd, elogind or similar. This is likely to involve
manually adding users to groups.

If the above does not work, try running with `WLR_RENDERER=pixman labwc` in
order to use the software rendering fallback

Family calendar, went for a custom framed screen as opposed to a mirror surface, may at a mirror surface later.

IMG_0811 (1).jpeg

Hardware
Hardware is a Pi Zero 2W with a cheap portable monitor (Firebat).

MM Configuration
Modules is a simple set up of a CalendarExt3 with the default weather and time pulling five ics calendars from google (a calendar for each person plus a shared one).

OS
Used the MagicMirrorOS for the build, had some intermittent issues as noted in a troubleshooting thread that @KARSTEN13 and @SDETWEIL gave some good pointers on so could put in a workaround.

Server Side
On the google side, have written two Google Scripts to transform the calendar entries a little.

Script 1
Events are prefixed by “[CalendarName]” so clear which calendar the event belongs to without colour coding.

Script 2
Also a script that takes a calendar and copies the events to another, optionally padding the times for travel times (hardcoded) and rewriting the the title so that the original time is included. This allows me to consolidate several calendars into one.
End result is (for example) my calendar for display (SW), has copied into two ics feeds, one of any gym classes I have booked (padded with travel time) and one from Tripit unpadded. Similar with my wife’s calendar with her gym bookings.

As an update, based on the pointers from @KARSTEN13 and @SDETWEIL, have a workaround.

Had three issues going on.

1:
I found that on a graceful reboot (shutdown -r now) that it would generally start fine, but not on an ungraceful reboot (power cycle the machine).

Looks like when it was ungraceful reboot, the labwc container would show with uptime of (for example) five hours when ‘docker ps’, even though the machine was rebooted 20min ago after ‘docker compose up’ was executed by install.sh. Whereas the magicmirror container would have recently started.

I assume kind of lock file confusing things?

Workaround was to change the first ‘docker compose up’ install.sh to ‘docker compose up -d --force-recreate’

2:
I’d also included a pause and --force-recreate at the end of the install.sh and noted it was never executing as per @KARSTEN13’s suggestion.
Looked like the install.sh script was hanging at docker compose pull.
Commented that out.

3:
Lastly, the initial ‘docker compose up -d --force-recreate’ in install.sh would still fail often with the mm container restarting with logs as per the original post.

With a 7 min pause and then second ‘docker compose up -d --force-recreate’ it seems to start the second time well (3min wasn’t enough, 5min was better, 7min seems to work).

Workaround is a bit on the slow side, at some point will see if can refactor it a bit so that a pull for updates occurs.

Extract of resulting install.sh below.

_info "--> Pulling docker images and starting magicmirror"
# need sudo for docker here if docker was installed with this script

# use up so mm can start if there are already local images
_info "--> Pre Start Pause for 2min"
sleep 120

_info "--> Start and recreate"
$_sudo docker compose up -d --force-recreate

#_info "--> Pull Pause for 1 min"
#sleep 60
# pull new images
#_info "--> Image Pull"
#$_sudo docker compose pull

#_info "--> Restart Pause for 1 min"
#sleep 60
# restart (only if new images pulled)
#_info "--> Restart stopped"
#$_sudo docker compose up -d

_info "--> Final Pause for 7 min"
sleep 720

_info "--> Final  start and recreate"
$_sudo docker compose up -d --force-recreate

if [[ "$_sudo" == "sudo" ]]; then
  _info "--> Reboot needed, starting in 120 sec. (use ctrl-c to skip)"
  sleep 120
  sudo reboot now
fi

# cleanup
$_sudo docker image prune -f

@karsten13 said in MagicMirrorOS build intermittently not starting mm container (Version 2.30):

the script /opt/mm/install/install.sh is executed with every reboot.

As workaround you could add

Is that executed on the OS boot, or by one of the containers as they start?

I was thinking of a workaround like that to introduce a pause. Given the low machine spec, it seems to be busy for about 5min after sshd starts, so will just try a 300 sec sleep.

An observation, if I power cycle the pi, there is a good chance of it not starting up with the errors in the original post.

Once leave it for five min for all the processes to start (and fail), then run docker compose up -d --force-recreate, it seems to be stable from then on and works well.

Apologies, user error.

scottwalsh · Feb 13, 2025, 10:19 PM

@sdetweil
The host is a pi zero 2w - so is on the low spec side.

Hi,

I’ve recently built a mm using MagicMirrorOS (which uses the docker install) to use as a family calendar on the wall. Have in configured for the information I want

However, I am finding if power cycle it, sometimes the calendar does not load up and just have a blank screen.

If execute:

scottwalsh@calendar:/opt/mm/run $ docker compose up -d --force-recreate

Then, it loads.

Have some Linux background from many years ago, but docker is new to me - so not sure where to look to work out how to resolve.

From looking at the logs (some extracts below), looks like the mm container isn’t connecting to Xserver.

Any suggestions where to look for useful logs to work out the issue?

Thanks, Scott
