5" MIPI DSI Touch screen touch event not work when using balenaOS multiple containers on raspberry pi 4

Product support balenaOS

Do anyone have this situation?
When using single container, touch events work fine; however when using multiple containers, touch events don’t work properly.
I already add privileged: true to the main container, unfortunately, it doesn’t work.

What should I do to fix this problem?

the similar issue, https://github.com/balena-os/balena-raspberrypi/issues/300

In this issue, @danielmahon provides the solution to add ENV UDEV 1 in the Dockerfile; however it’s not work for me.

I use the other solution, which add the script file, udevadm.sh, and execute in the Dockerfile.

#!/bin/bash

#!/bin/bash

chroot /proc/1/root /bin/bash <<"EOT"
udevadm control --reload-rules
udevadm trigger
echo $$

Thanks!
