Linux

Im a total child in terms oft Linux distros. Since im sick of Microsoft i decided to switch my gaming completely to Linux (Xbox to Tower with bazzite, switch to steamdeck). Im quite happy that i installed the distro by my self and found the place where i was able to change the keyboard layout. Because i want to play in my livingroom form the couch i got a bluetooth keyboard. The mouse i already have connected perfectly the keyboard didnt. I tried finding a solution online but soon realised that i have to learn to read the Linux lingo.

Can please someone teach me or point me in the right direction were i can learn the basics. Treat me like i know nothing about distros (because i dont) and PC (because i barely do).

This is also to try the Linux community. Show me what you got.

Edit: First of all, im very happy how this turned out. You people are very kind. I did manage to connect everything and got it running. Now i need to find out why dota 2 isnt running smothly.
