Description Allan Bogh 2016-01-04 18:13:42 UTC 
The Lenovo Yoga 900 trackpad and touchscreen do not work with the default kernel. I've upgraded to 4.4-rc7 to get the latest changes, but this version still doesn't have the correct drivers.

A workaround has been created, which requires a custom kernel compilation. It would be nice if the hardware works with the default kernel though.

Here is the initial fix that lead to a workaround.

Here is an article I created to help others using Ubuntu.
