Installation & System Requirements

Ubuntu Desktop Edition

• 700 MHz processor (about Intel Celeron or better)
• 512 MiB RAM (system memory)
• 5 GB of hard-drive space (or USB stick, memory card or external drive but see LiveCD for an alternative approach)
• VGA capable of 1024x768 screen resolution
• Either a CD/DVD drive or a USB port for the installer media
• Internet access is helpful

Screen resolution will be set at the highest your graphics card can handle but when you boot-up you should be given a "Low graphics mode" option which allows you to set it to something better for your monitor.

Hardware produced in the last few years or with an efficient architecture or machines built for a specific purpose can often work well with less. For example, a netbook with an 8 GB SSD will work well although there wont be much room for saving stuff directly onto the drive so Ubuntu's free 2 GBcloud could help a lot. A machine with a crumbling, 15 year-old, slow, 8 GB, IDE hard-drive probably won't work and doesn't really compare with the netbook anyway. It might be worth trying Ubuntu but really start looking at other distros.

All 64-bit (x86-64) CPUs should be fast enough to run Ubuntu and can run the 32-bit (x86) version as well. For an optimized installation (and especially for those wishing to run more than ~3 GiB of RAM) however, a 64-bit installation CD is available. The 32-bit version tends to be easier to use and runs into less problems.

Ubuntu Desktop 11.04 and up uses Unity as the default GUI while the previous releases used GNOME Panel by default. In order to run Unity the system needs a more capable graphics adapter – see more here or below:

* 1000 ΜHz processor (about Intel Celeron or better)

* 1024 MiB RAM (system memory)

* 3D Acceleration Capable Videocard with at least 256 MB

From experience, we all know that it is recommended to have 2048 MiB RAM to properly run a day to day Ubuntu.

A good start should be with minimum 1024 and recommended 2048 MiB RAM.

Machines that are 10 or more years old (originally preloaded with "Windows ME" or "Windows 2000") that don't meet these guideline will probably require some work to revive (the RAM usually needs to be upgraded to the level described above). You could try a lighter-weight distro or a minimal install of Ubuntu.

The easiest and most effective step towards a minimal install of Ubuntu is to install a lighter-weight Desktop Environment such as Xfce (see Xubuntubelow), LxDE (see Lubuntu (officially supported from 11.10 onward)) or Enlightenment to name just a few of the most popular. Some of the larger applications, such as LibreOffice, could be swapped for very much lighter equivalents but for more information about doing a minimal install please see the guides at https://help.ubuntu.com/community/Installation#Minimal%20installations.
