<![CDATA[Error 'failed to load kms_swarst' - can I ignore is screen is loading?]]>Hi there,
I’m new to raspberry pi but not MagicMirror. Due to the pi shortage I had installed MM on my mac to test things out with no problems but now I have the pi i’m struggling more than I thought I would!

I’ve tried reinstalling and running out of the box (ie no extra modules installed, no changes to any files) and I keep getting a ‘failed to open kms_swrast’ error and no solutions I’ve googled have worked. Here is the entire output after I run npm start

> magicmirror@2.23.0 start

If the screen is loading, can I just ignore the error? Any help would be greatly appreciated!
Thank-you

you can get rid of the error message by adding

export ELECTRON_DISABLE_GPU

before doing npm start

if you use pm2, then add it to the script pm2 uses to launch mm
