I have just bought a Raspberry Pi 7" touch screen for testing, but apparently Info-Beamer does not seems to be able to boot on this sceen. The screen is just black.
I have tried to test it with a standard RPi OS without problems.
That’s certainly unexpected. I just connected a Pi3 to my 7" display and both stable and testing version worked out of the box. Can you connect HDMI as well to check if it is used instead?
I currently use it to test setups without needing a full size external screen.
Obviously this means that I’m not able to use the video configuration in the device detail page, and due to some small bug the display is actually upside down ( only when booting as I have the setup rotated in the settings page ) there is apparently a small tweak that can be made to rotate the display to the correct orientation.
After a little troubles shooting it seems that the problem is the Raspberry Pi 3 A+.
I am testing with a working HDMI screen instead of the RPI 7" Screen.
When connecting the RPi Zero - everything works. When I move the SD card from the Zero (or creates a new one) and place this into the RPi 3, the screen stays blank.
I have tried with two different RPi 3 A+ - and they are working fine with a standard Linux OS on the 7" screen.
Ok. That’s at least something. But I’d really love to understand why it doesn’t work with that funny screen. Especially as that really looks like normal HDMI from the Pis point of view.
