Frankenstein is a surname. The mad scientist’s name was Dr. Victor Frankenstein. Since the monster wasn’t endowed with a first name, the only name it would have is Frankenstein: the same last name as its father.
It might be Mint or an issue with your laptop. I’ve been using Arch for a while and haven’t had major performance issues. Before I used Arch, I used Pop!OS and didn’t have any issues either. What are your laptop specs? Have you already looked into Nvidia Optimus? Have you tried other distros?
