ozone_platform_x11.cc(239)] Missing X server or $DISPLAY

[noonas]

I have a RasPi3 with a 7" LCD (DSI connector not HMDI) connected and it works.
I have a wireless keyboard/mouse and I can use the terminal just fine.

I have installed MM as per instructions, but when I try to start it it says:

noonas@HomeassistantPi:~/MagicMirror $ npm run start

magicmirror@2.23.0 start
DISPLAY=“${DISPLAY:=:0}” ./node_modules/.bin/electron js/electron.js

I have tried to set the $DISPLAY variable to 0:0, same error comes.

What can I do??

@noonas you installed on the lite/text mode only version of Raspberry pi OS

MM needs the full version with desktop… as the browser uses graphics mode always
see https://docs.magicmirror.builders/getting-started/requirements.html#hardware

if you had used my install script it would have stopped because of this and told you
see

@sdetweil Thanks, Installed the GUI/Desktop and now it works!!
Now trying to remove the fat margins of the screen for the modules…

[sdetweil]

@noonas see the main.css for the margins

then change by adding entry to custom.css

[noonas]

@sdetweil said in ozone_platform_x11.cc(239)] Missing X server or $DISPLAY:

main.css

Got it, thanks works better now! This is aweome…
May build my own module.

@noonas see my SampleModule
https://github.com/sdetweil/SampleModule

and of course there are a lot to look at
