If you have a non functional touchpad on Linux this might fix it for you.
New driver available built on kernel 4.17, presumably will be rolled into 4.18.
An EZbook 3 Pro user verifies on the Manjaro forum that a new kernel patch fixes the problem on his notebook. So lets hope it also works on the X4. “Hi philm! I update mirror to unstable branch and then linux417 4.17.11-1 showed up to pamac so I installed and solved one and for good touchpad bug on ezbook 3 pro!! Thank you very much!!”
