Acer C720P Touchpad and Touchscreen are not working

chromebook touchpad touchscreen

I have installed Ubuntu in a Chromebook Acer C720P but neither Touchpad nor Touchscreen nor Microphone are working, I have flashed the ROM using John Lewis help and Ubuntu 14.04 was installed from scratch.

Any suggestion will be appreciate!


The linux-3.13 kernel in Ubuntu 14.04 does not have drivers for the C720P touchpad and touchscreen. You will need to install linux-3.16.7-ckt4 or later. You can upgrade the kernel by following these instructions.
