If anyone else encounters this issue, this means that KDE or any other desktop environment you installed has conflicted with gnome. I fixed this by completely purging kubuntu desktop. Also, if you get a "Ubuntu on Wayland" DE that means you installed nvidia correctly. I hope this helps anyone who encounters this issue.
