Choice of Linux Distro
Choice of Linux Distro
I’d follow the suggestions of others, though I can only set it up on very old machines like those with Pentium 4 processors.
For an older machine, Mageia XFCE is a solid option. If previous KDE versions ran slow, another KDE distro might be better. Cinnamon tends to be resource-intensive. Mint relies on Cinnamon as well. I believe Mageia is a decent choice, but for Debian-based setups, consider SolydXK or Xubuntu. On the Mageia download page, select 'livecd' for a first-time XFCE installation. Whatever you pick, use etcher to create the USB key.
With those specifications, Xubuntu would be the ideal choice.
You're not alone in finding Lubuntu and Ubuntu a bit confusing at first. While they share some similarities as Linux distributions, they differ in focus—Ubuntu is more general-purpose, while Lubuntu leans toward lightweight desktop experiences. Their core features and user bases aren't identical, which can make the comparison tricky.
