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?
replace HDD with SSD, number one thing to do if possible.
lxde or lxqt are quite a bit lighter then xfce.
you could try tiny core linux. it really depends what programs you want to run.
