«Which Linux should I install?» is probably the most common question from newcomers, and the answers found online are often cheerleading rather than advice. In reality all distributions use the same kernel and largely the same programs. What changes is how they are packaged, updated and supported. Choosing well means understanding which of these differences matter to you.
What really sets a distribution apart
The release model
- Fixed release: a new version comes out at regular intervals and, in between, mostly receives security fixes. The system changes little and predictably. Ubuntu, Debian, Linux Mint and Fedora follow this model, at different paces.
- Rolling release: there are no versions, the system updates continuously and always has the latest software. Arch Linux and openSUSE Tumbleweed are the best-known examples. You gain novelty and lose predictability.
Length of support
Every two years Ubuntu publishes an LTS (Long Term Support) version with five years of standard updates; interim releases are supported for nine months. Debian stable receives security updates for about three years, later extended by the LTS project. Fedora supports each release for about thirteen months, so it must be upgraded to the new version roughly once a year. For a computer that just needs to «work» for years, long support is a big advantage.
The desktop environment
Look and feel depend on the desktop environment, not on the distribution. GNOME has a clean, modern approach; KDE Plasma is highly configurable and familiar to people coming from Windows; Cinnamon, developed by the Mint project, recalls the classic desktop with a menu and taskbar; Xfce is lightweight and suited to older computers. Many distributions offer editions with different desktops.
The best fit, by profile
| Profile | Suggested choice | Why |
|---|---|---|
| First experience, coming from Windows | Linux Mint | familiar desktop, graphical tools for updates and drivers |
| General use with plenty of documentation | Ubuntu LTS | very widespread, long support, many guides |
| Developer who wants recent software | Fedora | up-to-date versions but carefully curated releases |
| Server or machine to leave untouched for years | Debian stable | stability and predictability |
| Someone who wants to understand and build their own system | Arch Linux | manual installation, excellent documentation |
| Older computer with little memory | an Xfce or LXQt edition | lightweight desktops |
Hardware matters more than the name
Before choosing, check a few practical points:
- Graphics card: NVIDIA cards often need the proprietary driver. Ubuntu, Mint and Pop!_OS make it installable in a few clicks; on other distributions it takes a few more steps.
- Wi-Fi and Bluetooth: some recent chips need newer kernels. A brand-new laptop often works better with a distribution shipping a recent kernel, such as Fedora, than with an LTS from a few years ago.
- Printers and scanners: most work without extra drivers, but it is worth checking your model.
- Secure Boot: the major distributions boot with Secure Boot enabled; some smaller ones require turning it off.
The most reliable way to check all this is to boot the system from a live USB stick, without installing anything, and test networking, audio, webcam, suspend and screen brightness.
Derivatives: benefits and risks
Many distributions derive from others: Mint and Pop!_OS from Ubuntu, Ubuntu from Debian, Manjaro from Arch. A well-maintained derivative adds convenience and polished configuration. The risk concerns small projects: if the team behind them breaks up, updates stop. For a work computer it is better to pick a distribution with a large community or a company behind it and a history of regular releases.
Common mistakes when choosing
- Switching distribution at every problem: the same problem almost always reappears elsewhere, because it depends on hardware or configuration, not on the distribution.
- Choosing on looks: themes and icons can be changed in minutes on any distribution.
- Starting with Arch without experience because «you learn more»: you really do, but it takes time and a second working computer to look things up on.
- Using non-LTS releases on machines you do not want to touch: after a few months you have to upgrade to the next version.
A practical approach
In my work the criterion that works best is to start from actual use: who will use the computer, for what, and how much time they want to spend on maintenance. For most people the answer leads to a fixed-release distribution with long support, a familiar desktop and a large community. Curiosity about the alternatives can always be satisfied in a virtual machine.
In short
- All distributions share the kernel and programs: packaging, updates and support differ.
- Fixed release means predictability; rolling release means always-new software.
- Desktop environment and distribution are separate choices: you can have KDE or GNOME almost anywhere.
- Test your hardware with a live USB stick before installing.
- For beginners, Linux Mint or Ubuntu LTS; Debian for servers, Fedora for recent software.
