Description:

Axes swapping/matrix transforming incompatibility (screen becoming garbled, touchscreen becoming non-functional) with touchscreen device "SYNAPTICS Synaptics Touch Digitizer V04", as on the recently released Lenovo Thinkpad Yoga 14. Seems to occur primarily when switching between standard and 180 degree rotated configurations. I assume this is a problem like the one with ELAN Touchscreens detailed here -->(http://www.elfsternberg.com/2013/05/25/thinkpad-yoga-ubuntu-12/), but I should already have that fix.

I'm running evdev version 2.9.0

Here is the relevant portion of my output running xinput:
Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ SYNAPTICS Synaptics Touch Digitizer V04 id=10 [slave pointer (2)]
⎜ ↳ SynPS/2 Synaptics TouchPad id=13 [slave pointer (2)]
⎜ ↳ TPPS/2 IBM TrackPoint id=14 [slave pointer (2)]
And the relevant portion of output on xrandr:
Screen 0: minimum 8 x 8, current 1920 x 1080, maximum 32767 x 32767
eDP1 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 309mm x 174mm
