Bazzite is so user friendly that I could, and did, set it up on a Steam Deck...

...without a mouse or keyboard, with just the Steam Deck as a controller!

Then I figured out how to set up containers, and built a Debian environment, that can and did successfully compile different game engines from source.

Again, without a mouse or keyboard.

... Did I mention I'm currently crippled in the right wrist and shoulder and arm?

Bazzite on a Deck is extremely usable.

Just had to tweak the base Steam Control mapoing thingy a bit to be able to use common shortcuts, figure out how to do a kind of half southpaw layout for the mouse -> trackpad stuff.
