Lubuntu Utopic Unicorn 14.10 β1

We’re preparing Lubuntu 14.10, the Utopic Unicorn, for distribution in October 2014. With this early Beta pre-release, you can see what we are trying out in preparation for our next version (with  3.16.0-11 Ubuntu Linux kernel).

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, the famous web browser.

  • ... and, of course, based on Ubuntu 14.04 LTS.

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

  • LTS Support (3 years).

Lubuntu Applications

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 standard lubuntu desktop.

14.04 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 an error with Celeron M reporting "NON-PAE CPU" and would like to install Lubuntu 14.04, please see this page

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.

Known Issues

Installation

  • Some keyboard layouts may have problems (such as UK ones). You can workaround the problem by removing all the ibus-* packages (see 1284635))

Graphics and Display

Applications

  • Network indicator on the panel may not start at login. You can start it manually by launching "nm-applet" in a terminal. Some others autostarted applications may also be affected (such as automatic updates). See 1308348 for the details and the ETA for the fix.

PPC

  • PPC has several issues and workarounds, please refer to the documentation on the wiki.

  • Slideshow on PPC Desktop ISO was removed because of a bug on webkit (996568)

  • Installer on Desktop PPC (Ubiquity) is enable to resize and split partitions. you can use Gparted before launching the installation to make the modifications to your partitions (1307994)
