22.04 GPD P2 Max Digitiser AKA Touchscreen

[deakus]

Respun a Mate 22.04 ISO to install on my GPD P2 Max. Everything works fantastically except for the Digitiser/Touchscreen. Noticed on your stream back in June back on these little devices, you did not test the touchscreen. https://www.youtube.com/watch?v=V1GZ3mFznkU

I have tried an upgrade from 20.04, Built a respin of the 22.04 ( after installing cd-boot-images-amd64 ). Tried running the installation on the actual device umpc-ubuntu.sh

No error messages, nothing in logs files, just touchscreen does not work.
