Re: I've got Xubuntu 20.4 running on an Atom. So I guess Lubuntu could too.
It's important to remember that this is only a comparison of Ubuntu re-spins.
It is just as important to remember that 32-bit machines have NOT been relegated to the dust-bin simply because one distro developer decides to no longer support 32-bit; there are many distros which still do, and in an elegant fashion; and legions of people who still use 32-bit machines because they "just work"...and work very well.
"MX Linux MX-18 & 10-year-old EeePC netbook - Fantastic"
"Updated: April 1, 2019"
"...It's fast and responsive. LibreOffice, which wouldn't even start previously, opens within about 10 seconds..."
"...remember, this is a 10-year-old machine that until three weeks ago was destined for scrap. Now it's chirping melodies and videos, I'm using the latest software just fine. Only 280-290 MB memory footprint.
...MX Linux MX-18.1 Continuum has restored life to my netbook. It runs beautifully fast, it's elegant, loaded with real, practical goodies. The tremendous part is really the speed. This mini-laptop was weak even when I bought it, but to be able to keep using it in a nice fashion a decade later is truly an achievement."
