Asus TUF F15 FX506HM Trackpad issue

I am new to Linux and I just installed Ubuntu on a new ASUS TUF F15 FX506HM, and I had a couple of problems regarding the Wi-Fi adapter and the touchpad. In order to solve the Wi-Fi problem I updated the kernel to the latest version, but that did not solve the trackpad issue (did not solve the Wi-Fi problem completely either, apparently there are no drivers yet for the Wi-Fi adapter I have mt7921e, but this is a different discussion for another time).

To solve the trackpad issue I followed a couple of tutorials on YouTube and discussions on different forums and the solutions found were to edit the grub file in /etc/default/grub and to modify the two lines containing "GRUB_CMDLINE_LINUX_DEFAULT" and "GRUB_CMDLINE_LINUX" introducing different values for those two fields. No solution worked.

Please help me, I do not know what to do next. This is the output from the xinput command:

    WARNING: running xinput against an Xwayland server. See the xinput man page for details.

I am running Ubuntu 21.04 with the kernel 5.12.10. Thank you for your help and attention!

Today, all of a sudden, the touchpad started to work for me under Arch Linux. Try updating your system.

Libinput identifies the touchpad as:

Device:           ELAN1203:00 04F3:307A Touchpad
Kernel:           /dev/input/event258

And XInput identifies it as:

⎜   ↳ ELAN1203:00 04F3:307A Mouse               id=15   [slave  pointer  (2)]
⎜   ↳ ELAN1203:00 04F3:307A Touchpad            id=16   [slave  pointer  (2)]
