I had an Aspire One D270 laptop with a 32-bit Intel Atom CPU and 1 gigabyte of RAM, so I installed Debian with Xfce on it, but even then it’s running way too slow.
Is there anything I can do to make the laptop faster and more responsive given its limited memory?
I have that exact machine in my electronics “graveyard”.
Peppermint OS was my GO-TO for speed and driver support out of the box. You can also stick in a 2GB SODIMM of ram. It will only recognize 1.5GB but still 50% more ram.
You need something like DamnSmallLinux, not Debian. Debian users about 800 MB of RAM with XFce, on a clean boot. It requires a minimum of 2 GB with a modern browser (one tab, 4+ GB with more tabs). DamnSmallLinux uses about 128 MB RAM on a clean boot, and with the Netfront browser about half a gig. Definitely better for such a laptop than any modern distro.
