Touchpad Fujitsu UH-X is not detected in Ubuntu 20.04

I tried to install Ubuntu 20.04 dual boot with Windows 10 on My UH-X. I found that

1. The touchpad can work properly on Windows 10.
2. I run Ubuntu 20.04 kernel 5.10.4 and tried to check with xinput command. It's not shown the touchpad in the list.xinput_Fujitsu UH-X
3. I tried to edit grub as the recommend in ask.ubuntu which they claimed that can solved this problem in previous medel but it's not work in UH-X.grub editor

Please help me solve this problem?

That's what worked for me.

1. Load Terminal with Ctrl-Alt-T
2. sudo apt install xserver-xorg-input-synaptics
3. sudo reboot
4. sudo modprobe i2c_hid

It started working right after 4), not sure if steps 2 and 3 were even necessary. Also I have to run 4) every time I log in, adding it to start-up scripts doesn't work for some reason

For ubuntu 21.10 and Fujitsu Lifebook UH,

sudo modprobe i2c_hid

did not work, but

sudo modprobe i2c-hid-acpi

worked.

Insert this line in /etc/modules:

i2c_hid

That way, the module is launched at boot automatically.
