Lubuntu 13.10 (Saucy Salamander) released

 Julien Lavergne has released lubuntu 13.10. Lubuntu 13.10 is available here:

What is Lubuntu ?

Lubuntu is a flavor of Ubuntu based on the Lightweight X11 Desktop Environment (LXDE), as its default GUI. The goal is to provide a very lightweight distribution, with all the advantages of the Ubuntu world (repositories, support, etc.). Lubuntu is targeted at "normal" PC and laptop users running on low-spec hardware. Such users may not know how to use command line tools, and in most cases they just don't have enough resources for all the bells and whistles of the "full-featured" mainstream distributions.

With many LXDE components, Lubuntu also uses well-known applications, such as Firefox, Openbox, Pidgin, to name a few. The Lubuntu project wiki contains more information on the project and the applications used available.

Features

  • Based on the lightweight LXDE desktop environment.

  • Pcmanfm, a fast and lightweight files manager using gio/gvfs.

  • Openbox, the fast and extensible, default windows-manager of LXDE.

  • Lightdm, using the simple GTK greeter

  • Firefox, as the new choice for lubuntu 13.10

  • ... and, of course, based on Ubuntu 13.10.

See the complete list of applications on https://help.ubuntu.com/community/Lubuntu/Setup#Applications

Improvements since Lubuntu 13.04

  • New version of pcmanfm / libfm (1.1.0) including a built-in search utility.
  • Artwork improvements, including new wallpapers, community wallpapers, new icons ...
  • Removing catfish, since pcmanfm has its own search utility
  • Fix a very old bug causing gnome-mplayer to crash with some CPU (P4)
  • Several fixes for the image viewer gpicview.

System Requirements

A Pentium II or Celeron system with 128 MB of RAM is probably a bottom-line configuration that may yield slow yet usable system with a reduced lubuntu desktop.

13.10 32 bit ISO require your CPU to have Physical Address Extensions, or PAE. "PAE is provided by Intel Pentium Pro and above CPUs, including all later Pentium-series processors (except most 400 MHz-bus versions of the Pentium M)."

If you have a pre-Pentium II CPU, start from the Ubuntu 12.04 mini.iso.

and please consider the tips in this link

If you have a Celeron M or Pentium M CPU without a PAE flag but with PAE
capability, use fake-PAE according to this link
https://help.ubuntu.com/community/Lubuntu-fake-PAE

For PowerPC, it is known to run on a G4 running at 867MHz with 640MB RAM.

For Intel based Macs, lubuntu should run on all models.
