The touchpad does not work after installing ubuntu 20.04 on an hp laptop

Hello, during the installation, the touchpad worked completely, after installation, it stopped working at all. I found a solution on the internet to make changes to /etc/default/grub:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash psmouse.proto=bare"
GRUB_CMDLINE_LINUX="i8042.reset i8042.nomux i8042.nopnp i8042.noloop"

After that, the touchpad is working, but the two-finger scroll doesn't work. Please help me solve this problem.
