I have a setup of two monitors and a small Bamboo Pen&Touch that is sitting in front of my keyboard like a giant touchpad on a laptop. It's in portrait orientation so that I can place my keyboard wrist rests comfortably on the left and right of the tablet (I have a split keyboard). I'd like to use the tablet in relative mode because if I want a decently distortion free mapping of pen to screen, the usable tablet area would be reduced to only about a third of the tablet's height. With
xsetwacom set "Wacom BambooPT 2FG 4x5 Pen stylus" Rotate ccw
and similar for touch and eraser I get the rotation I want, and with something like
xinput set-prop "Wacom BambooPT 2FG 4x5 Pen stylus" 'Coordinate Transformation Matrix' 1 0 0 0 3 0 0 0 1
I get a pretty distortion free mapping of pen movements to movements on the screen (i.e. if I draw a circle on the tablet, I pretty much get a circle on the screen). However, when I switch the mode to relative, like
xsetwacom set "Wacom BambooPT 2FG 4x5 Pen stylus" Mode Relative
I have a distorted mapping again - apparently the transformation matrix isn't respected in relative mode.
Is there a way to get undistorted mapping in relative mode?
BTW, obviously I could do the rotation with the matrix transform instead of with "Rotate ccw" as well, but unfortunately, this still does not seem to be supported in relative mode.
