Issue when installing on vanilla RPi4 + Bullseye Desktop installation
Opened this issue · 2 comments
Attempting to install and run on RPi 4 with vanilla Bullseye installation.
The screen lights up white, and I can see the touchscreen is working when I run in dual screen mode and touching the hat screen moves the mouse on the HDMI screen, but I have got nothing but a blank white screen from the hat.
Is this hat compatible with RPi 4 and the latest Bullseye release?
Bullseye has changed the way these displays are controlled. Procedure needs to e adapted for Bullseye.
For now use Raspberry Pi Os Legacy (= Buster)
I have just retried this by building a fresh Buster and trying to install. Still no luck and a blank white screen.
Desktop Image installed via Raspberry Pi Imager choosing Buster Desktop install.
Diagnostics below. Is there any other information that would be useful?
