What Are the Prerequisites for Installing Ubuntu on a Mini PC?
Installing Ubuntu on a Mini PC requires a compatible device (64-bit processor, 4GB RAM minimum), a USB drive (8GB+), and a stable internet connection. Verify hardware compatibility via the Ubuntu Certified Hardware list. Backup existing data to prevent loss during installation. Download the Ubuntu ISO file and use tools like Rufus or BalenaEtcher to create a bootable USB drive.

How to Create a Bootable Ubuntu USB Drive for Mini PC Installation?
Use BalenaEtcher or Rufus to flash the Ubuntu ISO onto a USB drive. Select the ISO file, choose the USB drive, and start the process. Ensure Secure Boot is disabled in the Mini PC’s BIOS/UEFI settings. Boot from the USB by pressing F12/ESC during startup and selecting the USB drive from the boot menu.
For advanced users, Ventoy offers a multi-boot solution that allows storing multiple ISO files on a single USB drive. After flashing, verify the USB integrity using checksum tools like md5sum or sha256sum. If the Mini PC uses UEFI firmware, ensure the USB is formatted as FAT32 and the ISO supports UEFI boot. Testing the USB on another device beforehand can prevent installation failures. Persistent storage configurations are also possible for portable Ubuntu setups, though they require manual partitioning during the creation process.

Which Ubuntu Version Is Best for Mini PCs?
Ubuntu LTS (Long-Term Support) versions like 22.04 Jammy Jellyfish are ideal for stability and long-term updates. For lightweight performance, consider Ubuntu MATE or Xubuntu. Check the Mini PC’s specs: older hardware may require lighter flavors, while newer devices can handle standard Ubuntu Desktop with GNOME.
Ubuntu Core is another option for IoT-focused Mini PCs, offering transactional updates and strict security confinement. For media-centric devices like home theater PCs, Ubuntu Studio provides preconfigured audio/video tools. Always match the OS version to your workload—LTS for servers, interim releases for cutting-edge software. Below is a comparison of popular Ubuntu variants for Mini PCs:
| Flavor | DE | RAM Usage | Best For |
|---|---|---|---|
| Ubuntu Desktop | GNOME | 1.2GB+ | Modern hardware |
| Xubuntu | XFCE | 512MB+ | Older devices |
| Ubuntu MATE | MATE | 800MB+ | Balanced performance |
How to Optimize Ubuntu for Better Performance on a Mini PC?
Disable startup apps in “Startup Applications,” switch to Xfce/LXDE desktop environments, and use preload (sudo apt install preload). Enable zRAM via sudo apt install zram-config. Remove unused snaps and limit background processes. Use systemd-analyze blame to identify slow boot services.
Additional optimizations include configuring swappiness values for better RAM management—set vm.swappiness=10 in /etc/sysctl.conf. Replace heavyweight apps with alternatives like AbiWord instead of LibreOffice for basic text editing. Use TLP for power management on battery-powered Mini PCs (sudo apt install tlp). For headless setups, install Ubuntu Server and add only necessary packages. Monitoring tools like htop and glances help track resource hogs in real time.
Expert Views
“Ubuntu’s modularity makes it perfect for Mini PCs, especially for IoT projects. However, users should prioritize driver compatibility checks before installation. Tools like Mainline let you install newer kernels for unsupported hardware, but stick to LTS releases for critical systems.” — Linux Systems Engineer, IoT Solutions Firm
