since I moved to Ubuntu 17.10 with Wayland and Gnome I don’t actively develop this script any longer since the desired functionality seem to work out of the box. |
The Thinkpad X1 Yoga is a convertible laptop, so you can flip the screen over and your laptop is now a tablet. Tablets are typically used in different orientations. To detect orientation it is supplied with a BMA 150 accelerometer.
Since version 4.9-rc2 linux kernel contains patches for this device so it works nicely with iio-sensor-proxy. It seems that Kernel 4.10 has an issue with this which was resolved in Kernel 4.11.
This project provides a script dealing with automatic screen rotation and some other tablet/laptop convenience features.
So far, I’ve tested it with Ubuntu 17.04 and appreciate any feedback.
-
Linux kernel 4.9-rc2 or >= 4.11
-
linux packages python3, python3-dbus, python3-gi, onboard, iio-sensor-proxy
This python script thinkpad_x1_yoga_rotation.py provides the following features:
-
Listen to dbus signals from sensor proxy and check if display orientation has changed. In case of a change event the display is rotated approriately using
xrandr. The X1 Yoga has 3 wacom devices: finger touch, pen stylus and pen eraser. For all of them rotation is adoption appriately. -
When the laptop is converted to tablet mode touchpad and trackpoint are switched off and a onboard keyboard is started. When going back to laptop mode the orginal state is restored.
-
disable finger touch if stylus is close to the display
-
upon termination, restore "normal" screen orientation, switch on touchpad and trackpoint
./thinkpad_x1_yoga_rotation.py
Now rotate your display by 90 degrees and screen orientation should follow.
