This kernel configuration should fix it. https://asus-linux.org/wiki/g14-and-g15/hardware/touchpad/ I don't know how it translates to modules though. I think it's the order in which all kernel modules are loaded. There where times that it just worked. /etc/modprobe.d/99-elan.conf softdep elan_i2c pre: pinctrl_amd softdep hid_elan pre: pinctrl_amd sudo mkinitrd fixed it bad news, it only works on some boots. I can't explain it. The same problem exists in XiaoXin pro 13 API.

The solution works for me. With different hardware on my laptop based on dmesg output, I created /etc/modules-load.d/99_touchpad.conf softdep hid_i2c pre: pinctrl_amd softdep hid_generic pre: pinctrl_amd Fixed in more recent kernel version. |
