Resuming topic from:
This touchpad is identified on several cheap Chinese made notebooks. And some not so cheap, such as my Vaio FE14.
The touchpad is sometimes detected at boot, sometimes not. A manual fix can be achieved by typing at the terminal:
sudo rmmod i2c_hid sudo modprobe i2c_hid
That immediately fixes the touchpad, including multi-touch support. However, the left and right physical buttons do not work.
Need a solution to automate the commands above during boot time (without the need to type the sudo password).
And, most importantly, need a solution for the physical buttons.
I have tried kernels 5.4 LTS, 5.6, 5.7 and the new 5.8.0 stable, always the same problem. On kernel 5.3.18 though, it was working.
Philm posted a patch to AUR to this problem in 2018 (back on kernel 4.xx) but the file has since been pulled from AUR. It only addressed the touchpad though, not the physical buttons.
Thanks a lot any help here.
