Great choices have been talked about already… hmm…
Let me add one from my side before I leave.
Try Bodhi linux or Arch with enlightenment.
The Enlightenment DE should run decently on that hardware (Turn off OpenGL rendering and composting if it doesn’t)
Bodhi further uses Midori as the browser making the distro almost completely suitable for underpowered machines.
Otherwise try Ubuntu Mate, that one’s doing really well I’ve heard cuz its trying to run even on lower hardware than what Lubuntu supports…
or try Antergos Mate (Ive never tried or heard about how well it performs)…(Go with Antergos Mate if you dont waana be confused between
pacman -S and
apt-get install as you switch between systems)
I personally would’ve installed Windows XP on that system. Even though its dead but it can outperform Lubuntu or anyother Openbox DE any day!
How? I have old Pentium4 computer that runs on 96MB RAM (128 minus 32MB for Video output, 96 it is!) and I dont think any thing from the linux world would allow me to browse internet, listen to songs, watch movies on a computer with 96MB RAM, I can do all that with Window XP.
on 512MB RAM+Windows XP, you can play GTA Vice City, GTA Sanandreas, NFS Mostwanted, NFS unerground(I remember those days).
