Invert Y is needed (together with swap XY) for some touchscreens :
- LeadingTouch screens (at least for some of them)
- CarTft 8in4 (USB ID=0eef:0001)

Wouldn't it be useful to force those settings for touchscreen devices
which you can detect? That would make it work out-of-the-box on those
devices.

Hi,

That's what I am doing, but userland (using udev rules),
since I am really unsure we can rely on USB id...

For now, I don't think it's a good idea to force any behaviour,
that can cause regressions on other ones.

In a longer term, it would be good to keep a list of all those screens
and see what should be the prefered behaviour per identification.

Note, I don't have any screen anymore.

Thanks for feedback
