Touchscreen of my new notebook was reporting touchscreen has no
range report which turned out to be Z-axis related and I thought
that always passing z=0 might solve the problem.
And it indeed mostly solved the problem. I can move the mouse and
click inside the modular Xorg. The only problem is that the mouse
moves two times faster to the right and 4-5 faster to the bottom.
Basically, it works like if I had a small touchpad at the top left
corner of my screen.
If I'm in a text mode and run 'wsmoused -d /dev/wsmouse1', the
cursor doesn't move at all but it flashes (in the center of the
screen) when I touch the screen.
I wonder where should I make the last change to restore 1:1 mappings
between movements and screen pixels?
Excerpts from dmesg, xorg.conf and my patch to dev/usb/uts.c are below.
