I am having problems getting the touchscreen of the official raspbery pi 7 inch display to work having a Raspberry Pi 4 8GB with tha latest updates.

I am using Flutter 2.5.2 with the latest commits from the repositories (flutter-pi and flutter-engine).
The graphical display is fine and with the keyboard I can run the application. But with the touchscreen I can't use the gui.

I have already checked with evtest if events arrive and it looks like the events arrive:
No device specified, trying to scan all of /dev/input/event*
Not running as root, no devices may be available.
Available devices:
/dev/input/event0: NOVATEK USB Keyboard
/dev/input/event1: NOVATEK USB Keyboard System Control
/dev/input/event2: NOVATEK USB Keyboard Consumer Control
/dev/input/event3: NOVATEK USB Keyboard
/dev/input/event4: vc4
/dev/input/event5: vc4
/dev/input/event6: generic ft5x06 (00)

can you try running without the -i (path here) argument? I thought the sentence In most cases, there's no need to specify this option. in the usage and not providing an example invocation in the usage would be enough to stop people from using it 😄

if it still doesn't work without it, are you running the latest pi OS based on debian 11? bc I haven't tested with that yet

EDIT: That compositor error is interesting though. Maybe they switched to the full KMS driver now. The FormatException also shouldn't be happening, I need to look into that too.

Thanks for your quick response!

Same problem withput -i

Yes, I use the latest image

EDIT: That compositor error is interesting though. Maybe they switched to the full KMS driver now. The FormatException also shouldn't be happening, I need to look into that too.

I switched to the full KMS driver

I will try with a previous Raspian OS image.

UPDATE: Do it with 2021-05-07-raspios-buster works fine!!

Thanks!

This is a kernel bug, was fixed recently: raspberrypi/linux#4736
That's not in any stable release though, so you need to use rpi-update to get the fix.

Touch will work after that, but you'll get spurious touch events at the bottom right of the screen (see raspberrypi/linux#4749)

(Just noting in case anyone else encounters this problem)
