Linux localhost 3.17.0-031700rc6-generic #201409211935 SMP Sun Sep 21 23:37:11 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux But I also tested using the Ubuntu 14.10 beta Live USB image and the problem is fixed in the 14.10 beta. I'm not sure how Xorg, udev and the kernel interfact when deciding whether a device is a 'touchpad' or just a 'pointer' but there must've been some change in Xorg or Udev that gets it working in 14.10 beta. ** Attachment added: "Xorg.0.log" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1372520/+attachment/4213523/+files/Xorg.0.log -- 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/1372520 Title: On Lenovo Yoga 2 Pro laptop PS/2 Synaptics TouchPad detected as pointer device by Xorg Status in “linux” package in Ubuntu: Incomplete Bug description: In the current kernel release for trusty (linux- image-3.13.0-35-generic 3.13.0-35.62) the touchpad on my Lenevo Yoga 2 Pro laptop is correctly detected as a touchpad device.
