MM won't launch at startup, but will launch manually

ajgonzales

I installed MM via sdetweil’s script on Ubuntu 24.04. Everything seems to work fine after installation, but after a reboot MM doesn’t start up. Checking the pm2 logs shows these errors, and then it just keeps looping.

[35781:0511/163537.061675:ERROR:ozone_platform_x11.cc(244)] Missing X server or $DISPLAY
[35781:0511/163537.061869:ERROR:env.cc(257)] The platform failed to initialize.  Exiting.
Authorization required, but no authorization protocol specified

I can run MM successfully using

npm start

from the MagicMirror folder. Any ideas on how I can get it to run at startup?

Hi, this is how I’m running it for now, maybe it will help someone.

I will install PM2 according to the instructions

I will skip the command “pm2 startup”

After installation i proceed like this

i will create another boot file

cd ~
nano mm_start.sh

Add the following lines:

echo Start PM2......
pm2 start mm.sh
read;

set permissions

chmod +x mm_start.sh

we will set up the script after booting Ubuntu

now i can start and stop services at will.

@ajgonzales what user were you logged on as when you can my script?

@ajgonzales said in MM won't launch at startup, but will launch manually:

[35781:0511/163537.061675:ERROR:ozone_platform_x11.cc(244)] Missing X server or $DISPLAY

is 24.04 using wayland instead of x11??
do

ps -ef | grep -i way

is a terminal window

sdetweil

@ajgonzales I am downloading 24.04 now to test in vm…

@sdetweil
was logged in as a user, not root. got the same errors after running the fixuppm2 script and rebooting. here are the results from the other command. looks like it does use wayland:

@ajgonzales ok thanks.

sdetweil

@ajgonzales yep, I can recreate this… so far no hack fix has helped…

I now have my system where it won’t finish booting… pm2 is uninstalled…

so something is different between UBUNTU and RASPI OS
cause we don’t see this problem on raspi

In case anyone else has this issue, I was able to able to get it to run via pm2 by running this command first:

xhost +si:localuser:[username]

Next steps are to figure out how to automatically run that command at startup prior to MM.

sdetweil

@ajgonzales add that to the launch script

you can find that by doing
pm2 status
then use the name or number of the row of the app

pm2 info x
where x is the name or number

can you give more info on the system?

lsb_release -a
uname -a

@sdetweil
I did try adding the command to the first line of the mm.sh script in the installers folder but that didn’t work. Here’s the sequence I run after rebooting, after which I have no issues.

pm2 stop 0
xhost +si:localuser:[username]
pm2 start 0

Here’s the output from those other two commands:

lsb_release -a

@ajgonzales yeh 24.04

pm2 has an issue on 24.04 during boot up. I opened an issue a couple weeks ago.
https://github.com/Unitech/pm2/issues/5820

I think you are also running the new Wayland display manager…

to verify

ps -ef | grep wayfire

so x11 commands won’t work
