The attached is a proof-of-concept solution - it adds an event generation (KEY_ROTATE_DISPLAY) in addition to http://comments.gmane.org/gmane.linux.kernel/2058487.
Let's try whether this event is generated for userspace and whether it meets the need. If it does, I will work with upstream on a proper solution. ** Attachment added: "thinkpad_acpi.c" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1644670/+attachment/4784461/+files/thinkpad_acpi.c -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1644670 Title: cannot use tablet mode lid sensor on yoga 460 Status in linux package in Ubuntu: Confirmed Bug description: See https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1644047 for machine logs.
