@garnoopy what is on the display before MagicMirror starts?
it it part of the desktop? does the display appear in the display configuration panel?

what os version, bookworm, 64 bit. hard on pi02w due to small memory size

garnoopy

@sdetweil the standard desktop is on the screen. Bookworm 64 bit.

I’ll have to look to see if the display is listed… but since the desktop shows seems like it will be. The screen just goes black (not off) when I start MM.

@garnoopy Do you have enabled SPI on your pi?
And: Do you have configured the correct overlays for running the 3,5‘‘ Display?

@garnoopy can you open a browser and make it display on that screen, may have to drag it

garnoopy

Yes, I enabled SPI.

I had to follow these instructions to get the screen to work, specifically these config updates:


Add a "#" in front of the line "dtoverlay=vc4-kms-v3d"

add this line at the end of the file " dtoverlay=piscreen,speed=18000000,drm "

(remove the double inverted commas "")

I will check the browser when I get home from work. But file manager, terminal, settings, everything else pulls up just fine.
