## Configuration

### Automatic rotation

Install iio-sensor-proxy-gitAUR. Under GNOME, rotation will happen automatically. Under i3, you can use this script in the background:

This article or section is a candidate for merging with i3.

Notes: This script is not device specific and should be added to the i3 page instead. (Discuss in Talk:Lenovo ThinkPad P40 Yoga)

    #!/bin/sh
    # Requires https://github.com/hadess/iio-sensor-proxy

    dbus-monitor --system interface=org.freedesktop.DBus.Properties,member=PropertiesChanged,path=/net/hadess/SensorProxy 2> /dev/null |
            sed -n -u -e '/string "AccelerometerOrientation"/ {n ; s/\s*variant\s*string\s*"\(.*\)"/\1/p}' |

In order to have your touchpad, Trackpoint, touchscreen and stylus also change orientation, install xrandr-align and run the following script at startup:

    #!/bin/sh
    # Requires https://github.com/wolneykien/xrandr-align

    for input in \
            "Wacom Co.,Ltd. Pen and multitouch sensor Finger touch" \
            "Wacom Co.,Ltd. Pen and multitouch sensor Pen stylus" \
            "ETPS/2 Elantech Touchpad" \
            "ETPS/2 Elantech TrackPoint" \
            "Wacom Co.,Ltd. Pen and multitouch sensor Pen eraser" ; do
            xrandr-align monitor --input="$input" &
    done
