I have a new ThinkPad X220 Tablet with Kubuntu 12.04. When I rotate the screen 90° with a script, the fonts of all programs that I open after the rotation have ugly huge fonts.

#!/bin/sh

# Find the line in "xrandr -q --verbose" output that contains current screen orientation and "strip" out current orientation.

rotation="$(xrandr -q --verbose | grep 'connected' | egrep -o  '\) (normal|left|inverted|right) \(' | egrep -o '(normal|left|inverted|right)')"

# Using current screen orientation proceed to rotate screen and input tools.

case "$rotation" in
        normal)
                # rotate to the left
                xrandr -o right
                xsetwacom set "Wacom ISDv4 E6 Pen stylus" rotate cw
                xsetwacom set "Wacom ISDv4 E6 Finger touch" rotate cw
                xsetwacom set "Wacom ISDv4 E6 Pen eraser" rotate cw
                ;;
        right)
                # rotate to normal
                xrandr -o normal
