Help with official touchscreen cwith Android

Sun Mar 21, 2021 11:27 pm

Hi all I have lineage os running on my Pi 4 4gb model with no issues. Just recently purchased the official raspberry pi touchscreen and have it all connected I see the rainbow boot screen and then nothing the screen is backlit but black. Changed the address card different pi 4 still same issue. Disconnected the screen and works perfect again on my monitor reconnect it back to touchscreen and black screen again. Tired rasbian and that works fine on the touchscreen so not sure why it won't display anything? Please help I'm stumped.


Thanks!!!!

Current builds of the LineageOS does not work with the official display using hardware graphics rendering. I think it should be possible to switch to software graphics rendering and get it to work though.

The new linux kernel version 5.10 is required to use hardware graphics rendering to work with the official display. Android 12 will use the 5.10 kernel.
