The Lubuntu team is proud to announce the release of Lubuntu 15.04. Please download it here:
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.
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
For more detail, please see the full list of applications.
Lubuntu is a good operating system for many old computers, but not for all of them. Some computers have too little horsepower or memory. A rule of thumb is that the computer should not be more than 10 years old.
For advanced internet services like Google+, Youtube, Google Docs and Facebook, your computer needs at least 1 GB RAM.
For local programs like Libre Office and simple browsing habits, your computer needs at least 512 MB RAM.
The minimum specification for CPU is Pentium 4 or Pentium M or AMD K8.
Older processors are too slow and AMD K7 has problems with flash video.
Graphics chip / card
Nvidia, AMD/ATI/Radeon and Intel work out of the box, or the system can be tweaked to work fairly easily. You can get help at the Ubuntu Forums. With such graphics, or if you don't know, try the current Lubuntu version.
