What Is Xubuntu and Who Is It Best For?
Author: Domeny.ForSale editorial team Published
In brief: Xubuntu is an official Ubuntu flavour featuring Xfce, a desktop environment valued for its low resource requirements and traditional desktop layout. It can work well on an older computer and as a programming system, but it cannot overcome the limitations of a weak processor, limited memory or a worn-out drive. Before installing it, it is best to boot the system from a USB drive and check that your hardware and required applications work.
How does Xubuntu differ from Ubuntu?
Ubuntu is a Linux distribution: a ready-to-use operating system with a collection of software and an update mechanism. Xubuntu uses the same foundation and repositories, the sources of the software packages installed on the system. The main difference users see is the desktop environment: instead of GNOME, which standard Ubuntu uses, they get Xfce.
The desktop environment handles the desktop, panels, application menus and windows, among other things. Xfce offers a traditional way of working without requiring elaborate visual effects. It usually leaves more resources available to applications than more feature-rich environments, although actual usage depends on the system version, configuration and running services.
Xubuntu is therefore neither a separate system written exclusively for old computers nor a specialist distribution for the IT sector. It is a full-fledged, general-purpose operating system with a lighter desktop. The project’s official name is Xubuntu, with a capital X.
Will Xubuntu speed up an older computer?
The biggest gains are likely when your current desktop environment uses a substantial share of the available memory and puts a load on the computer as soon as it starts. A lighter desktop can make menus more responsive, improve window switching and make working with a few simple applications more comfortable. That does not mean every task will become faster.
For example, an older laptop with 4 GB of RAM and a working SSD may be suitable for editing documents, using the terminal and browsing a few web pages. The same hardware may slow down during video conferences or when working with many browser tabs. In that situation, the applications are the main bottleneck, rather than the desktop itself.
Before choosing a system, check three things:
- RAM: you need enough not just for the system, but also for your browser, editor and other programs you run.
- Storage: a slow or faulty drive can cause delays regardless of the distribution you choose. Replacing a mechanical hard drive with an SSD often makes a more noticeable difference than changing the desktop alone.
- Processor and architecture: very old hardware may not support current installation images. Check the official Xubuntu materials to confirm which architectures are supported.
Minimum requirements help you assess whether the system can run, but they do not guarantee a comfortable experience. Testing your own set of applications is therefore more informative than judging by the computer’s age alone.
Xubuntu for developers and IT professionals
Xubuntu’s usefulness for technical work comes from its Ubuntu foundation, not from any special desktop features. It provides a terminal, the APT package manager, and development and administration tools. You can use Git, Python, compilers and an SSH client, among other tools, depending on your needs and the availability of suitable versions.
The traditional Xfce desktop may suit people who work in an editor, terminal and browser and mainly want a simple interface. Choosing Xubuntu alone will not, however, speed up compilation of a large project or reduce the requirements of a complex development environment. Containers, virtual machines and local databases still need enough memory and a capable processor.
It is therefore not automatically the ideal solution for every developer. Before migrating, check the availability of your company’s VPN client, required applications, drivers and security tools. Software designed exclusively for Windows or macOS may not have a compatible equivalent for Linux.
How can you test Xubuntu without installing it?
Live mode lets you boot the system from a USB drive without installing it on the internal drive. This is a good way to make an initial check of hardware compatibility. Running from a USB drive may be slower than running from an SSD, so this test will not precisely reflect performance after installation.
- Download the installation image from the official Xubuntu website. Check the supported architecture, the support period for that particular release and information about known issues.
- Create a bootable USB drive using a tool for writing system images. Writing the image will erase the existing contents of the selected USB drive.
- Boot the computer from the USB drive and choose to try the system rather than install it.
- Test Wi-Fi, sound, the camera, touchpad, an external monitor, and sleep and wake functions.
- Open the websites and documents you typically use. Assess whether the hardware can handle the way you actually work.
If the test goes well, back up important files before installing. The installer may change partitions or erase data from the drive.
Which release should you choose, and what should you check before migrating?
For an everyday computer, a supported LTS release—a release with long-term support—is a sensible starting point. Confirm the exact support end date for your chosen Xubuntu version in the project documentation; do not assume that all Ubuntu components and flavours have the same maintenance period.
Base your decision on a short test of your own workflow: launch the applications you need, connect your devices and check access to company services. If everything works and the computer remains responsive under your typical workload, you have a much stronger basis for installing it than the promise of a “lightweight Linux” alone.
