You will find those settings in power management if I rememver correctly. Is it plasma 6?

Their product might not be leading but they are sure not behind in software development. Mozilla devs work (or used to or started) on two most important projects (at least for me) Rust and Servo.

Angel - Raphael Sadeeq Its a hidden last track on vinyl edition. Appears in Luke Cage.

If I'm correct Xbox X is leading in hardware for console. You can't just come up with secure software and langauge through imagination. Both servo and and rust are culmination of what mozilla has been doing or want to do but could not in existing projects. So, yeah. Pretty relevent.

I would advise Opensuse Leap. I, personally don't use it but I have tried both.
