Introduction
In 2025, most new laptops ship with 8GB or 16GB RAM. But across Asia, Africa, and even parts of Europe, millions still use older devices with 2GB of memory. For them, running Windows 10, Windows 11, or macOS Monterey is painfully slow.
Luckily, the Linux ecosystem has dozens of lightweight distributions (distros) designed to give old machines a second life. Powered by the Linux kernel created by Linus Torvalds and supported by organizations like the Linux Foundation, these distros are free, secure, and efficient.
This guide explores the 7 best lightweight Linux distros in 2025 for laptops with 2GB RAM. Each section includes features, pros/cons, real-world performance, and who should use it.
