I need run a good Linux distribution on an old notebook with Athlon 1.2 and 128MB. I tried use a lite version of Win XP and some popular Linux distros but all of them was too heavy to this machine. The distro need be ease to use by a beginner user. It don't need be small, just light.I did a lot of research including here and I can't get a good answer.
What's a good lightweight distribution to run on old hardware?
distros
I have used Damn Small Linux many times to great success for older machines with little in the way of system resources.  It is based on Debian so you have the benefit of apt/ aptitude and has as I recall a couple of versions that come with different levels of pre-installed software.  http://www.damnsmalllinux.org
