Install on Surface Pro 4, Touchscreen not working

Hello guys,
I already install Clear linux on surface pro, but touchscreen not working. Any idea about it ?
Thanks aniway

There was this discussion a while ago about Surface Pro: https://github.com/clearlinux/distribution/issues/844

Basically it came to light that parts of the Surface Pro functionality on Linux require firmware and patches that are out-of-tree. So in the current state you’ll need to review and compile those parts yourself, unfortunately.
