The problem occurred upon a fresh install. I just tested kernel
4.5.0-040500-generic with no success.
However, I found a work around by applying this script for manual screen
and stylus rotation:
#!/bin/sh
# determine whether screen is already rotated
xrandr --current | grep primary | grep "left ("
if [ $? -eq 1 ];
then
xrandr -o left
# rotate stylus driver
xinput set-prop 13 "Evdev Axis Inversion" 1, 0
xinput set-prop 13 "Evdev Axes Swap" 1
else
xrandr -o normal
# un-rotate stylus driver
xinput set-prop 13 "Evdev Axis Inversion" 0, 0
xinput set-prop 13 "Evdev Axes Swap" 0
fi
I think the Systems Settings dialog for rotating the screen should also
rotate the stylus. Looks like this bug is related the 8 years old issue
of bug #217182.

Title:
Stylus coordinates wrong when screen is rotated on Dell Venue 11 Pro
7140
Status in linux package in Ubuntu:
Confirmed
Bug description:
I am using the pre-release 16.04 Ubuntu Xenial Xerus (development
branch) with kernel 4.4.0-15-generic on a Dell Venue 11 Pro 7140.
Touchscreen and Stylus are recognised out of the box:
xinput --list
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer
(2)]
⎜ ↳ Synaptics T Pad V 01.31 Touchpad id=9 [slave pointer
(2)]
⎜ ↳ SYNA7500:00 06CB:780E Pen id=13 [slave pointer
(2)]
⎜ ↳ SYNA7500:00 06CB:780E id=14 [slave pointer
(2)]
When I am manually rotating the screen by 90° using the System
Settings option (automatic screen rotation does not work), the
touchscreen and touchpad work as expected, however, the stylus is not
using the correct coordinates and the cursor is not following the
stylus position. When I move the stylus left/right, the cursor moves
up/down, and vice versa.
I had hoped to get a work around by disabling and re-enabling the
stylus after rotating the screen using
xinput --disable "SYNA7500:00 06CB:780E Pen"
xinput --enable "SYNA7500:00 06CB:780E Pen"
but this didn't solve the problem.
