Two days ago my Chuwi Lapbook Air 14" arrived with Windows 10 pre-installed on it. I installed elementaryOS 5 (based on Ubuntu 18.04 LTS) and it works perfectly: recognizes the eMMC drive (the notebook does not have hdd it uses eMMC), all Fn keys work as supposed to, keyboard's illumination also works, except for the touch-pad. I read a lot of articles on the subject and I see there are some people who made it work and almost everyone states that this is a kernel problem and is fixed in the more recent versions (after 4.15 versions). However, I tried updating the kernel to 4.18, even to 4.19, tried compiling a raw kernel on the particular machine, but unfortunately I get no results in any of these ways. The touchpad is recognized by the system as ALPS:0001, tap to click and two-finger click both work as respectively left click and right click, but the cursor doesn't move. What may cause the problem and do you have any idea how to solve this issue?

When pressing F2 key (enable/disable touchpad) It starts working for about 20-30 seconds. and then stops again. Can be reactivated with F2 key again, but the result is the same. When is deactivated the last `dmesg` message states: `[ 3955:030432] i2c_hid i2c-ALPS0001:00: i2c_hid_get_input: incomplete report (32/10763)`

It can stay active for even longer if I constantly am using it. The moment I lift my finger up for more than 5 seconds it dies and I have to reactivate it again.

**Edit:** After a system update, the touchpad is now working (as a pointing device and not the buttons, but tap-to-click is fine). The only problem is that it works ONLY while charging, if I remove the charger and try to use it in an "On-Battery" mode, the touchpad turns off. Which doesn't make much sense, as I could use an external mouse if I'm situated (charging), but need the touchpad exactly when the charger is unplugged :)
