Official 7 Inch touchscreen not detected #821

Closed LewisSpring closed 8 months ago

LewisSpring commented 10 months ago

What were you doing?

  1. Connect Raspberry Pi Official 7 Inch Touch Screen before first boot
  2. Install desktop environment using provided script via SSH
  3. Attempt to control backlight brightness and interact with DE via touch

What did you expect to happen?

  1. Touch works in the desktop environment
  2. Backlight can be controlled via /sys/class/backlight/...
  3. evtest command shows the touch input device

What happened instead?

  1. The touch does not work
  2. The backlight does not exist in /sys/class/backlight/...
  3. evtest command does not show the touch input device

Did the same happen when running OctoPrint in safe mode?

Additional Information

I didn't have any issues with Buster based images. I have checked all cables. I have tried troubleshooting with existing information on the web with no luck. I have reimaged the SD card as a troubleshooting step.

[x] I have read the FAQ.

Thanks!

Not sure how to test this ATM, I have a official touchscreen but I have no time to set it up and to try boot, if anyone has any input that would help. It might be worth to ask at: https://community.octoprint.org/
