To be fair, this is not a problem in Unity (which handles display changes just fine) it's a problem supporting the position sensor on the Yoga 3 and integrating it with the udev system to provide feedback to the X11 server and invoke xrandr.
Many devices have position sensors, and each device is different and needs bespoke software to get such rotation working. ** Changed in: unity (Ubuntu) Importance: Undecided => Wishlist ** Changed in: unity (Ubuntu) Status: New => Confirmed -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to unity in Ubuntu. https://bugs.launchpad.net/bugs/1484039 Title: yoga 3 screen does not rotate Status in unity package in Ubuntu: Confirmed Bug description: Hi Developer Team! i don't know if you have developed it as a feature or not, but Lenovo Yoga 3's screen rotates while flipping the screen back or holding it vertivalli - just like a pad.
