What distro would you recommend for a 32-bit old Acer One laptop?
It's an old model (Acer One D257) Processor is Intel Atom. Memory is 1GB DDR3 with 320 GB of HDD. I currently Have MX 21 running on it, but I need to reinstall because I forgot the root password. Since I'm reinstalling the OS, I thought I'd ask here for recommendations for an OS that makes the most of this oldie.
Debian based distros can be very different from each other. Ubuntu, Mint, Pop!, etc are all based off debian. I think what the commenter you're replying to is saying is to install the stock debian image, because that's the lightest version of debian.
I used to like Debian based (and still do; I use it on my server with no intention of switching) but Opensuse is great on the desktop and supports 32 bit. Even tumbleweed is rock solid.
