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?
Try Bodhi Linux - you can burn it to CD/USB or copy it on a Ventoy USB stick to test before installing and it is available for 32 bit systems
