from the mainline the last semi working is the rc7 (4.14.0-041400rc7 ...
We have other kernel branches and I tried the drm-intel-next thinking
that something labelled intel has more compatibility. I was right,
indeed the touchpad was partially working (no buttons). Here it is the
last working one: http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-
After this, touchpad is not working anymore. I am a noob but a think
that we have 2 ways to debug the problem:
1) see what changed after the drm-intel-next 2017-12-03 kernel...
2) build this 2017-12-03 kernel (or the rc7) with your buttons patches...
Even if my PC was more powerful than it is, I don't think that I am
skilled enough to do these things... :(

Touchpad stops working after reboot on Apollo Lake
Status in Linux:
Status in linux package in Ubuntu:
On the Jumper EZBook 3 Pro (V4) laptop, using an Apollo Lake N3450
processor, if you install Ubuntu 17.10 (or less) with isorespin and
use rEFInd as bootloader (this is the only way to get linux booting on
this laptop) everything works out of the box, but after a reboot or
two the touchpad stops working. Both in Ubuntu and Windows 10. The
only way to restore functionality is to boot from usb key ubuntu 17.10
respined, or disassemble laptop and detach-reattach battery cable.

There has to be a bug in the kernel. Any way to avoid this?
