Ubuntu, Fedora, Debian Testing, Arch Linux. They all run the Linux kernel. Everything else — the installer, the defaults, the community, the upgrade path — is different. This lesson helps you choose, then confirms it with a quiz.

A word on gaming-first distros — Nobara, Garuda, CachyOS, and similar.
These distros ship pre-configured gaming tweaks, Proton layers, custom kernels, and performance settings out of the box. That sounds great — and it might be, briefly. But they carry a serious risk that only shows up later: when something breaks, you don't know which of the dozens of pre-applied customizations caused it.
Real case: one of our group ran Nobara and hit, within a short period: a system freeze, a corrupted update, a broken display manager, a black-screen boot, and a kernel panic — all before getting a stable working desktop. Each of those is resolvable on a clean base system where you know what's installed. On a gaming-focused distro with 30 pre-applied patches, you're debugging someone else's configuration.
Build from a clean base. Debian Testing or Arch — install your games, apply your own tweaks, know what you changed. You'll spend less time recovering from mystery failures.
The Quiz
