Which distribution should I choose if I just want it to work?

Ubuntu. End of discussion. Yeah, the Arch Linux people will tell you to compile everything from scratch, and the Debian purists will lecture you about package freshness, but Ubuntu just works without drama. [Around 34% market share](https://itsfoss.com/linux-market-share/) didn't happen by accident.

Probably. Modern Linux supports most WiFi chips out of the box. The exceptions are usually brand-new laptops with WiFi 7 chips that are so new the drivers haven't been written yet, or really old stuff with proprietary Broadcom bullshit. Real talk: Intel WiFi chips work perfectly 99% of the time. Broadcom requires proprietary drivers that break every other kernel update. MediaTek is hit-or-miss. Realtek RTL8821CE will make you hate life. If you're buying new hardware, `lspci | grep -i network` is your friend - Google the exact chip model before you buy.

Can I actually game on Linux now?

Yeah, surprisingly. Steam Proton runs most Windows games without you having to think about it. Anti-cheat systems are still a pain in the ass (looking at you, BattlEye and Easy Anti-Cheat), but [around 40% of Steam games](https://www.protondb.com/) work perfectly. The Steam Deck proved Linux gaming is real. Pro tip: Check ProtonDB before buying a game. "Gold" and "Platinum" ratings mean it works great. "Bronze" means you'll spend 2 hours tweaking launch parameters. "Borked" means save your money. Valorant's Vanguard anti-cheat will never work on Linux because Riot wants kernel-level access that no sane person should give them. Apex Legends works perfectly, Destiny 2 is fucked by anti-cheat.

Why does my printer hate Linux?

Printers are the devil's own technology and they hate everything, not just Linux. HP printers usually work because HP actually gives a shit about Linux support. Brother printers work great. Canon and Epson? Good luck. That ancient HP LaserJet from 2003? It'll probably work better on Linux than it does on Windows 11. Canon PIXMA series randomly stops working after any kernel update because Canon hates you personally.

Can I run Windows software on Linux?

Sometimes. [Wine](https://www.winehq.org/) works for older Windows software and some newer stuff. For anything important, run it in [VirtualBox](https://www.virtualbox.org/) or VMware. Adobe Creative Suite? You're stuck with Windows or macOS. Microsoft Office? Use LibreOffice or the web version like a normal person.

Will Linux break my computer?

No, but you might break Linux. The beauty of Linux is that when you fuck something up, it's usually your fault and you can fix it. Unlike Windows, which breaks randomly and gives you cryptic error codes that lead to forum posts from 2009.

What if I need to print something important right now?

Keep a Windows laptop around, or use the office printer connected to Windows. Linux printing works 90% of the time, but that 10% always happens when you need to print boarding passes at 5 AM before a flight.

Why do people say the command line is so great?

Because once you learn it, you can automate everything. Need to rename 500 files? One command. Need to find all files modified in the last hour? One command. Need to compress and upload logs to S3? Script it once, never think about it again.

Can I dual-boot Windows and Linux?

Yes, but Windows will eventually mess with your bootloader during an update. This is a feature, not a bug, according to Microsoft. Keep a Linux USB around to fix GRUB when Windows decides to "help" you.

What about Microsoft Office?

LibreOffice is good enough for most people. Google Docs works in any browser. If you absolutely need real Microsoft Office, run it in a VM or use Office 365 in the browser. Excel power users are stuck with Windows because LibreOffice Calc can't handle your insane macros.

How do I install software without breaking everything?

Use your package manager (`apt`, `yum`, `pacman`, whatever). Don't compile random shit from GitHub unless you know what you're doing. Don't run installation scripts as root unless you trust the source. Yes, this means reading documentation. Deal with it. War story: Never, ever do `curl https://sketchy-site.com/install.sh | sudo bash`. I've seen this nuke entire systems. If you must install from a script, download it first, read it, then run it. Your future self will thank you.

What happens when something breaks?

You Google the error message, find a Stack Overflow post from 2015, try the solution, and it works. If it doesn't work, you ask on Reddit and someone who's seen this exact problem 47 times before helps you fix it in 20 minutes. Real debugging tip: The first thing to check is `dmesg | tail` - kernel messages will tell you if hardware is acting up. Second is `journalctl -xe` for systemd logs. These two commands solve 80% of Linux problems. That "ACPI: Unable to turn cooling device [\_TZ_.TZ01] 'on'" error? Typical hardware incompatibility that won't break anything, just ignore it like the rest of us.

Why does everyone recommend the Arch Wiki?

Because it's the best Linux documentation on the internet, even if you don't use Arch. Those maniacs document everything in excruciating detail. Having an obscure hardware issue? Check the Arch Wiki. It's like having a Linux expert who never sleeps.

Which desktop environment should I choose?

GNOME if you like modern interfaces that assume you have giant monitors and fat fingers. KDE if you want to spend three days customizing everything. Xfce if your computer is from 2012. Cinnamon if you're a Windows refugee who wants a familiar taskbar.

Is enterprise Linux support worth paying for?

[Red Hat makes billions](https://www.redhat.com/en/about/press-releases) selling support for free software, so apparently yes. Enterprise support means when your critical system implodes at 3 AM on Sunday, someone answers the phone. That's worth a lot when downtime costs $10,000 per minute.

Linux Resources That Don't Suck

Link	Description
Arch Wiki	The best Linux documentation on the internet, even if you don't use Arch. When your weird hardware doesn't work, this is where you find the fix. Written by people who actually understand what they're talking about. The Arch Wiki saved me from a kernel panic at 2AM when Ubuntu's docs were useless.
The Linux Kernel	Official kernel releases. Unless you're a kernel developer or masochist, you don't need to compile these yourself. Your distribution handles this for you.
Linux Foundation	The nonprofit that somehow keeps the Linux ecosystem from descending into complete chaos. Also hosts other projects that keep the internet running.
Red Hat Documentation	Surprisingly good documentation, even though it's corporate. Written by people who have to support this shit in production, so they actually explain how things work.
Ubuntu	Just works. Great for beginners, servers, and anyone who wants to get shit done without fighting their OS. LTS versions if you want stability, regular releases if you like new features.
Debian	Rock solid, boring as hell, never breaks. Perfect for servers you want to set up once and forget about for five years. Packages are older than your grandmother but they work.
Red Hat Enterprise Linux	Costs money but comes with support. For when your boss needs someone to blame when things break. RHEL is bulletproof if you can afford the licensing.
Fedora Project	Red Hat's testing ground disguised as a distribution. Gets the latest features first, breaks accordingly. Good for developers who like living dangerously.
Arch Linux	For people who think Ubuntu is for noobs and enjoy compiling things from source. The documentation is amazing, the install process is hazing.
Linux Mint	Ubuntu for people who miss Windows XP. Familiar interface, reasonable defaults, fewer surprises than Ubuntu's GNOME experiments.
Unix & Linux Stack Exchange	High-quality Linux Q&A community with expert answers. Better moderated than forums, and you get actual solutions instead of flamewars about desktop environments.
Ask Ubuntu	Stack Overflow for Ubuntu. Usually has the answer to your problem, or at least someone who's had the same problem.
LinuxQuestions.org	Old-school forum that's been around forever. The greybeards here have seen every possible Linux disaster and know how to fix it.
DistroWatch	Tracks every Linux distribution that exists, including ones nobody uses. Good for finding that one weird distribution that does exactly what you need.
LinuxCommunity.io	Ad-free Linux community forum where enthusiasts and sysadmins collaborate. Better signal-to-noise ratio than Reddit, with actual peer-to-peer support instead of memes.
GitHub - torvalds/linux	The actual Linux kernel source code. Linus Torvalds still commits to this personally. Reading the commit messages is entertaining if you enjoy Finnish sarcasm.
LWN.net	The best technical coverage of Linux development. Worth the subscription if you care about kernel internals and don't mind articles that assume you understand C. LWN.net is worth the subscription if you can tolerate their academic tone.
Kernel Newbies	For people who want to contribute to the kernel but don't know where to start. Warning: kernel development is not for the faint of heart.
Linux From Scratch	Build Linux from source code, one component at a time. Educational masochism at its finest. You'll understand how everything works and hate yourself.
Ubuntu Server Guide	Actually readable server documentation. Covers the stuff you need to know without drowning you in enterprise buzzwords.
CentOS/RHEL Documentation	Enterprise-focused documentation that's surprisingly helpful. Written by people who have to maintain this stuff in production.
TLDP - Linux Documentation Project	Old-school HOWTOs and guides. Some are outdated, but the fundamental concepts haven't changed. Good for understanding the why behind commands.
CIS Benchmarks	Security hardening guides that actually work. Follow these if you want your Linux systems to not get pwned by the first script kiddie who finds them.
LinuxSecurity.com	Security advisories, news, and discussions about Linux security. Real security professionals share actual threat intelligence and hardening advice. Subscribe to their emails if you want to know when the next privilege escalation vulnerability drops.
Flatpak	Universal packages that work everywhere. Good for desktop apps, bloated as hell, but they work when distribution packages are outdated.
Snap Store	Canonical's answer to Flatpak. Slower to start, but works. The controversy around them is mostly religious warfare.
AppImage	Portable apps that don't need installation. Download, make executable, run. Simple concept that actually works.
Phoronix	Linux hardware benchmarks and performance analysis. Michael Larabel tests everything and publishes the results. Essential for understanding real-world performance.
9to5Linux	Daily Linux news without the corporate spin. Covers distribution releases, kernel updates, and actually important software developments.
It's FOSS	Beginner-friendly Linux content and tutorials. Good for learning about desktop Linux without getting overwhelmed by technical details.
