I have an "Iota flo 360" laptop running ubuntu studio 22.04LTS on which the touchscreen doesn't work. It's a cheap Celeron based machine, I have it dual booting and the touchscreen works on Windows 10. The default ubuntu studio install has X11 running not wayland.

The American Megatrends UEFI interface indicates it's an I2C device

I can do modprobe goodix
then dmesg contains

Most strangely I can do xinput but it comes up as a keyboard.

xinput test 15 shows no output when I touch the screen.
What can I try next?
