Since I prefer the standard gnome-session experience, I installed the "gnome-session" package and rebooted the system. And on the cog icon next to the sign in button, select the "GNOME" instead of ''Ubuntu" option before clicking the sign in button.

Touchpad
I increased the speed, enabled "tap to click", "two finger scrooling". and on gnome-tweak enabled click method to "fingers".
