[Bug 1810183] Re: numpad on touchpad doesn't work in ASUS Zenbook 14

@mohamed-badaoui

A real solution will be to get keyboard events directly from the
touchpad. Your script interprets clicks as keyboard events depending on
an area. These touchpads declare themselves as keyboards to i2c, that
means that most likely they can send the events.

This would be a perfect solution, because each device should know its
areas, available keys, etc.

The only thing to develop will be to a add detection to the kernel code,
and sending commands to enable it.

If this is not possible, then I can't see an easy clean solution. We
will need to have a user space driver, that will do the same as the
python script, but it will depend on each piece of hardware. And also
there should be different drivers for xorg and wyland. That looks too
complex to me and will never get into the distro.

Title:
numpad on touchpad doesn't work in ASUS Zenbook 14

Status in Linux:
New
Status in linux package in Ubuntu:
Confirmed

Bug description:
I have Asus Zenbook 14 UX433FA which I have installed Ubuntu 18.10 alongside windows 10.
The numeric keypads are within the touchpad and are supposed to be turned on by a button on the touchpad. This works well in Windows but doesn't work in Ubuntu.
I have tried to search for any related problems/solutions online but I haven't been able to.
I will appreciate any suggestion or help.
Thanks,
