I have Dell Inspiron 7591 installed with dual boot Ubuntu 18.04.5 LTS and Windows 10.
On installation touchpad was not working. The module i2c_hid seemed missing. When the module was loaded, touchpad started working fine. Although the module needs to be re-loaded every time after the reboot. Is there any way that the touchpad stays functioning without manually loading the module?
I tried Myx's answer. It didn't work.
Feel free to ask for any required details.
