Single command auto- installer, complete transformation pack from Ubuntu desktop to default Gnome desktop including all gnome core applications right after next login.
Extra beautiful 4k Ultra HD desktop wallpapers, animated cursors, my Adwaita default folders blue version, gnome login and boot screen logos, Custom blue Gnome (about) logo,Gnome extensions and much more.
This package must be installed right upon a clean Ubuntu minimal installation for the best experience.
Extract the contents to somewhere and navigate to the downloaded folder in terminal and type:
"sudo sh install.sh" (without Quotes.)
(Due to your system updates sometimes you may need to repeat this)
Check out "Help" folder for advanced customisation.
I'm not responsible for any probable damages on your system so use it with your own risk, it works fine on my system however.
