From dmesg, nvidia is not working with plenty of error, it will trouble touchpad with I2C bus.
If you don't want nvidia, please blacklist it.

And you can try psmouse.elantech_smbus=0 in kernel cmdline.

Adding psmouse.elantech_smbus=0 into GRUB disabled it completely :D

But using only intel graphics instead of nvidia seems to work!

Thank you very much!
