x64-compatible CPUs have been the norm for a very long time now, which is why most modern distros have dropped support for older 32-bit x86-only CPUs. Debian dropped it with Debian 13, so anything based on that - think Ubuntu, Mint, and others, would be in the same boat. 2GB of RAM would be pretty performance-limiting on most modern distros too.

That’s one of the reasons why things like Tiny Core and Puppy exist, though. Specifically for old/slow-by-today’s-standards systems. I haven’t used any of them because I’m not running anything that old, and I quite like modern KDE. I saw an Action Retro video on youtube the other day where he got Tiny Core running on a Pentium 133 with 128MB of RAM, lol.

I recently switched my laptop to Fedora 40’s KDE spin, and like it a lot. I look forward to upgrading.
