Raspberry pi 2 + touchscreen + buster + enabling Full fake KMS opengl driver -> blackscreen

Fri Feb 14, 2020 8:41 pm

Hey,

I only noticed this today, when i enable full / fake kms opengl display driver via raspi-config the official touchscreen screen remains black when entering X. It does display info at boot up but as soon as X starts it remains black. The desktop does start as i can connect using VNC but no matter what i do screen remains black.

This issue does not happen with the legacy driver and it also does not happen with the G2 option, the previous fake / kms opengl driver.

Any idea's ? or is the touchscreen / rpi2 not compatible with the latest opengl driver ?

I'm using official raspberry pi 3 supply for testing so it's not an undervoltage problem
