Re: Suggest me a light weight Fedora based distro
The Fedora 13 release notes state
Minimum RAM for graphical: 384 MiB
Recommended RAM for graphical: 512 MiB
And Xfce on Fedora uses much the same amount of memory as Gnome. Even switching to Fluxbox only save about 40MiB, and that's far less user-friendly.
With only 256MiB, you have the choice (keeping to the beginner-friendly distros) of Puppy, Slitaz, or Crunchbang. They all come as live CDs, so you can try before you install.
