I think this bug is related to a hardware failure/feature in the hinge mechanism. I could reproduce the auto rotation lock at a certain angle of the hinge.
This still does not explain why I could not change the orientation manually (why the "Orientation" setting in the "Display Settings" Menu showed no dropdown menu) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to iio-sensor-proxy in Ubuntu. https://bugs.launchpad.net/bugs/2018297 Title: ThinkPad Yoga 460 Auto-Rotation stoped working after suspension Status in gnome-shell package in Ubuntu: New Status in iio-sensor-proxy package in Ubuntu: Incomplete Bug description: The auto-rotation feature of my Laptop stoped working. - screen orientation was in landscape mode - closed the lid of my laptop => laptop entered suspension mode - opened the lid => laptop was waking up - screen orientation was in portait mode I could not change the screen orientation by rotating the laptop physically nor change the orientation manually (the "Orientation" setting in the "Display Settings" Menu showed no dropdown menu).
