Bug Description

On jammy, an XP Pen 13 tablet (shown in the hardware as "UGTABLET 11.6 inch PenDisplay") is unusable because the axes for the stylus are swapped: moving the stylus up on the screen moves the cursor to the left, moving it down moves it right, moving the stylus to the left moves the cursor up, moving it to the right moves the cursor down.

I am reporting this bug initially against Xorg, but the problem is present using either Xorg or Wayland.

I find recent references to being able to swap the axes with 'xinput set-prop <devid> "Evdev Axes Swap" 1. This fails for me with:

property 'Evdev Axes Swap' doesn't exist, you need to specify its type and format

https://unix.stackexchange.com/questions/685039/x11-how-to-invert-axis-on-touchscreen-matrix has commands that seem to work (xinput set-prop <id> "Coordinate Transformation Matrix") but the specific values listed there still have the vertical access reversed.

'xinput set-prop "UGTABLET 11.6 inch PenDisplay Pen (0)" "Coordinate Transformation Matrix" 0 1 0 1 0 0 0 0 1' appears to work but only if the tablet is configured as the top display.
