error: Couldn't create GBM surface for rendering - Rasberry pi 5 with 7 inch DSI official display about flutter-pi HOT 6 CLOSED

Can you try without the fkms change? Could be that no longer works on Pi 5, though it shouldn't be necessary anymore anyway.

If the issue persists, can you post the output of the raspinfo command?

from flutter-pi.

Sure, so I reinstalled OS to make sure that other changes I did will not affect it. I went through the setup process once again, skipping fkms change. Finally I ran into exactly same issue as before.

@ardera FYI I tried to use Pi4 with 64-bit Raspbian Bullseye instead of Pi5 and it works perfectly fine.

from flutter-pi.

running it on a rpi5 with a 3.5 inch tft display
getting this same error

@anirudh-walia That's not the same error. How is your TFT display connected to the Pi? What model?

from flutter-pi.

My bad just saw the first few lines it's a 3.5-inch TFT display connected via GPIO pins the display is working fine with touch and everything.
