I have a very, very old laptop with me. I don’t know the exact specs, but it has a single core celeron processor and 4GB of RAM. It’s an old little thing, maybe 15 years old.
I installed Debian on it with LXQT and it was chugging hard. I don’t expect it will run modern browsers anyways, so give me your best distros that can run on a potato and have a GUI.
If you want a GUI, Puppy Linux is for you:

Seconded, Puppy is super lightweight and easy to get on with, definitely worth a try.
