Magicmirror not using monitor for display
-
Hi
Not sure why but when I launch Magicmirror on bookworm with RPI4, the monitor display is on only for a few seconds when the pi is booting up but then just goes blank. When i use VNC, i see the MagicMirror as normal. If i stop MagicMirror, i can see desktop on VNC but the monitor is still off. It only ever comes on for about 5sec when i boot the Pi. How can i troubleshoot this? -
@rama3124 tell us more.
mm black screen is typically a module problem -
@sdetweil Worked it out! the monitor would just lose signal straight after the boot screen everytime. Turned out i just needed to change the resolution to a lower one, so i’m guessing my monitor was too old to support whatever resolution Bookworm was trying to push
