So a good place to start for anything is the arch wiki. It is very extensive and often helpful for people on any distro.
What keyboard do you have?
Edit: Also, just checking you’ve switched on your keyboard? Like your mouse, a wireless keyboard will have a small on/off switch somewhere.
Bazzite is a fine pick for someone who just wants to game. It is immutable so much lower chance of screwing up the system, and is based on Fedora Silverblue.
As I understand it, Endeavour is explicitly not for new users and instead is recommended as a new step for someone already familiar with a more beginner friendly distro?
My bets are on scrubbing of republican names.
I also think the rumours of Trump blowing Bill are what made Trump want to release them all of a sudden, and so we will see something that shows he didn’t do it or it wasn’t Bill, etc (whether faked or not).
I think Bazzite is a good distro for a beginner wanting specifically something to game on, but going for something common works too. I probably wouldn’t suggested Ubuntu to anyone these days but you can’t deny the long history of forum posts that come up whenever you search your problem.
It’s a nice thought, but his mouse is working and his keyboard is not, that’s why he’s asking.
