Ubuntu – Touchpad not recognized on new Ultrabook

14.04laptopsamsungtouchpad

I have a new Samsung ATIV Book 9 2014 Edition (930X5J-K01) and installed Ubuntu 14.04 LTS on it. The touchpad is not working at all. There is no cursor visible but an external USB mouse is working fine.

After upgrading the kernel to 3.15 RC2, an UNKNOWN input device is detected. But again, no mouse cursor appears. I tried many approaches to get the touchpad working, but nothing worked. Using an older version of Ubuntu, or another Linux dirso doesn't work too.

I uploaded additional debugging information, where you can see the new detected input device (ATML3000). Windows detects the Touchpad as HID\ATML3000&COL01\5&1579C925&0&0000

Output of cat /proc/bus/input/devices

dmesg Output:

Content of Xorg.0.log

Output of sudo lshw

I used HID Replay to check that the device is actually working, to see the generated output during some gestures Click here.

This is an upstream problem from the 3.15-rc kernel. A patch has been submitted here: https://patchwork.kernel.org/patch/4096321/

3.15 final should not contain the bug.

oh, and this is not a conflict with i2c_hid.
