#title Ubuntu System Requirements
#title Ubuntu System Requirements
<br>
This page details the hardware required to run '''Ubuntu''' and its derivative versions.
This page details the hardware required to run '''Ubuntu 7.04 (Feisty Fawn)'''.
Most people will want to install a desktop system such as '''Ubuntu''', '''Kubuntu''', or '''Xubuntu'''. A desktop system is typically used for personal computing tasks and has a graphical user interface (GUI), while a server system typically has a command-line interface (CLI).
Some of the hardware specifications quoted on this page are estimates. You may be able to run Ubuntu successfully on hardware of a lower specification than that specified, although performance is likely to be very poor.
== Recommended Minimum System Requirements ==
The '''minimum requirements''' are only likely to allow a server (non-graphical) installation to run well. The '''recommended minimum requirements''' should allow you to run a graphical installation of Ubuntu well.
The '''Recommended Minimum System Requirements''' should allow you to run an installation of Ubuntu well. While you can usually run Ubuntu on hardware of lower (and sometimes much lower) specification, performance will necessarily suffer.  Most users (''especially'' those new to Ubuntu) risk frustration if they ignore these suggestions.
== Desktop installation ==
=== Ubuntu Desktop (GUI) Installation ===
Most people will want to install a desktop system such as '''Ubuntu''' or '''Kubuntu'''. A desktop system is typically used for personal computing tasks and has a graphical user interface.
* 1 GHz x86 processor
=== Minimum requirements ===
* 512 MiB of system memory (RAM)
* 5 GB of disk space
* Graphics card and monitor capable of 1024x768
* CD-ROM drive
* ''Sound support''
* ''Internet access''
The first 1GHz processors were released in 2000, effectively meaning that computers manufactured prior to that will not normally be suitable for installation of Ubuntu in a GUI capacity (see below for information regarding Xubuntu however, which has lower system requirements).  Even so, this represents a '''huge''' pool of old machines: there is a good chance that even systems originally preloaded with ''Windows ME'' can run Ubuntu (though in such cases the RAM usually needs to be upgraded to the level described above).  Used systems which are newer than that (e.g. which originally shipped preinstalled with Windows 2000, XP, Vista, x86 OS X, etc.) will almost certainly run.  So long as they meet the Recommended Minimum System Requirements, even those on the older end of this spectrum, perhaps gathering dust in a closet or crippled by malware, can have new life breathed into them; once refurbished they definitely will work quite well for basic tasks such as playing music, web browsing, e-mail, document editing, etc. Rather than discarding or recycling such systems as they approach the end of their usable/supported life, please consider reuse with Ubuntu!
'''Note:''' All 64-bit (x86-64) CPUs (first released in 2003) should be fast enough to run Ubuntu and can run the 32-bit (x86) version; 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.

==== Visual Effects ====
''Visual effects'' provide various ''optional'' special graphical effects for your desktop to make it look and feel more fun and easier to use.  Even if your computer is powerful enough to run visual effects, you can turn them off and will still have a usable Ubuntu desktop system.
Visual effects are turned on by default if you have a GPU (graphics card or integrated chipset) which is supported.  Supported GPU manufacturers:
* ATI (some may require the '''proprietary''' fglrx driver)
* Intel (i915 or better, '''except''' GMA 500, aka "Poulsbo")
* NVidia (with their '''proprietary''' driver)
For more information on supported graphics cards, see [[UbuntuHelp:DesktopEffects|DesktopEffects]].
=== Ubuntu Server (CLI) Installation ===
* 300 MHz x86 processor
* 300 MHz x86 processor
* 64 MB of system memory (RAM)
* 128 MiB of system memory (RAM)
* At least 2 GB of disk space (for full installation and swap space)
* 1 GB of disk space
* VGA graphics card capable of 640x480 resolution
* Graphics card and monitor capable of 640x480
* CD-ROM drive
* CD-ROM drive
If your system has less than 192 MB of system memory, use the ''Alternate Installation CD''.
See also https://help.ubuntu.com/9.10/serverguide/C/preparing-to-install.html
=== Recommended minimum requirements ===
and old spec https://help.ubuntu.com/7.04/installation-guide/i386/minimum-hardware-reqts.html
* 500 MHz x86 processor
== Lightweight GUI alternative (Xubuntu) ==
* 192 MB of system memory (RAM)
If you have an old or low-spec computer or want to get the most out of your hardware, using a lightweight desktop system such as '''Xubuntu''' is recommended, as it should make more efficient use of your system's resources. Of course, even if you have the newest equipment out, you could still use Xubuntu.
* 8 GB of disk space
* Graphics card capable of 1024x768 resolution
* ''Sound card''
* ''A network or Internet connection''
'''Note:''' All 64-bit (x86-64) PCs should be able to run Ubuntu. Use the 64-bit installation CD for a 64-bit-optimised installation.
=== Recommended for Desktop Effects ===
''Desktop Effects'' are an experimental feature which has been introduced with the release of Ubuntu 7.04 (Feisty Fawn). Desktop Effects provide various special graphical effects for your desktop to make it look and feel more fun and easier to use. However, they require more resources than a standard Ubuntu desktop, and so you will need a more powerful computer in order to use them.
Desktop Effects can only be turned on if you have a graphics card which is supported. For a list of supported graphics cards, see [[UbuntuHelp:DesktopEffects|DesktopEffects]] for more information.
* 1.2 GHz x86 processor
* 256 MB of system memory (RAM)
* 8 GB of disk space
* Supported graphics card (see [[UbuntuHelp:DesktopEffects|DesktopEffects]])
== Low-spec computers ==
If you have an old or low-spec computer, using a lightweight desktop system such as '''Xubuntu''' is recommended, as it should make more efficient use of your system's resources.
If your system has less than 192 MB of system memory, use the ''Alternate Installation CD''.
If your system has less than 192 MB of system memory, use the ''Alternate Installation CD''.
'''Note:''' If you have a low-specification computer, certain features may be automatically turned off to conserve system resources. For example, if you have a graphics card with only a small amount of video memory (VRAM), the boot-up screen may not be shown.
'''Note:''' If you have a low-specification computer, certain features may be automatically turned off to conserve system resources. For example, if you have a graphics card with only a small amount of video memory (VRAM), the boot-up screen may not be shown.
=== Minimum requirements ===
Follow this link for detailed instructions: [[UbuntuHelp:Installation/LowMemorySystems|Installation/LowMemorySystems]].
* 166 MHz processor
Minimum system requirements for Xubuntu would fall roughly between Ubuntu Server and Desktop:
* 48 MB of system memory (RAM)
* 256 MiB of system memory (RAM)
* At least 1.4 GB of disk space
* VGA graphics card
=== Recommended minimum requirements ===
* 300 MHz processor
* 192 MB of system memory (RAM)
* 8 GB of disk space
* Graphics card capable of 800x600 resolution
== Apple Mac computers ==
* If you have a '''PowerPC Apple Mac''', use the Ubuntu PowerPC installation CD.
* All current '''Intel-based Macs''' should be able to run Ubuntu.
* If you have a Mac with '''less than 128 MB of system memory''', it is recommended that you install Xubuntu instead of Ubuntu or Kubuntu.
* If your system has '''less than 256 MB of system memory''', use the ''Alternate Installation CD''.
=== Minimum requirements ===
* iMac G3 with 233 MHz processor
* 64 MB of system memory (RAM)
* 2 GB of disk space
* 2 GB of disk space
* Graphics card (as supplied with computer)
* Graphics card and monitor capable of 800x600 resolution
=== Recommended minimum requirements ===
Regarding processors, a recent thread on the Ubuntu Forums describes a 500 MHz Xubuntu machine as being "too slow" and discusses alternatives: http://ubuntuforums.org/showthread.php?t=1267443
* iMac G3 with 450 MHz processor, or iMac/eMac G4
== Ubuntu Netbook Edition ==
* 192 MB of system memory (RAM)
If you have a netbook and a supported graphics card, using '''Ubuntu Netbook Edition''' (formerly "Ubuntu Netbook Remix") is an interesting option.  It has a nice interface adapted for smaller screens, and a selection of applications aimed at netbook users.
* 8 GB of disk space
Ubuntu Netbook Remix is designed to run well on netbooks with typically minimal specs, i.e.:
* Graphics card capable of 1024x768 resolution
* Intel Atom processor @ 1.6 GHz
* 512 MiB of system memory (RAM)
* 4 GB of disk space
* Screen of 1024x600 resolution
* Graphics chipset with support for visual effects
== LTSP thin-client computers ==
== LTSP thin-client computers ==
If you are intending to use a computer as a thin client (such as a client for an '''Edubuntu LTSP Terminal Server'''), only a low-specification computer capable of displaying graphics and connecting to a network is required.
If you are intending to use a computer as a thin client (such as a client for an '''Edubuntu LTSP Terminal Server'''), only a low-specification computer capable of displaying graphics and connecting to a network is required.
== Absolute minimum installation ==
Follow this link for more information: [[UbuntuHelp:HowToCookEdubuntu/Chapters/HardwareRequirements|HowToCookEdubuntu/Chapters/HardwareRequirements]].
The absolute minimum Ubuntu installation provides only a command-line interface and installs very few packages. You can add additional packages and a graphical interface manually.
In order to install the absolute minimum installation, use the ''Alternate Installation CD''.
It is possible that you will be able to install Ubuntu on computers with lower specifications than those given below. However, installation may be extremely difficult and Ubuntu is likely to run very slowly on such a system.
=== Absolute minimum requirements ===
* Intel 486 processor
* 32 MB of system memory (RAM)
* 300 MB of disk space
=== Absolute minimum graphical installation ===
* Intel Pentium 66 MHz processor
* 48 MB of system memory (RAM)
* 468 MB of disk space
* VGA graphics card

  1. title Ubuntu System Requirements

This page details the hardware required to run Ubuntu and its derivative versions. Most people will want to install a desktop system such as Ubuntu, Kubuntu, or Xubuntu. A desktop system is typically used for personal computing tasks and has a graphical user interface (GUI), while a server system typically has a command-line interface (CLI).

Recommended Minimum System Requirements

The Recommended Minimum System Requirements should allow you to run an installation of Ubuntu well. While you can usually run Ubuntu on hardware of lower (and sometimes much lower) specification, performance will necessarily suffer. Most users (especially those new to Ubuntu) risk frustration if they ignore these suggestions.

Ubuntu Desktop (GUI) Installation

  • 1 GHz x86 processor
  • 512 MiB of system memory (RAM)
  • 5 GB of disk space
  • Graphics card and monitor capable of 1024x768
  • CD-ROM drive
  • Sound support
  • Internet access

The first 1GHz processors were released in 2000, effectively meaning that computers manufactured prior to that will not normally be suitable for installation of Ubuntu in a GUI capacity (see below for information regarding Xubuntu however, which has lower system requirements). Even so, this represents a huge pool of old machines: there is a good chance that even systems originally preloaded with Windows ME can run Ubuntu (though in such cases the RAM usually needs to be upgraded to the level described above). Used systems which are newer than that (e.g. which originally shipped preinstalled with Windows 2000, XP, Vista, x86 OS X, etc.) will almost certainly run. So long as they meet the Recommended Minimum System Requirements, even those on the older end of this spectrum, perhaps gathering dust in a closet or crippled by malware, can have new life breathed into them; once refurbished they definitely will work quite well for basic tasks such as playing music, web browsing, e-mail, document editing, etc. Rather than discarding or recycling such systems as they approach the end of their usable/supported life, please consider reuse with Ubuntu! Note: All 64-bit (x86-64) CPUs (first released in 2003) should be fast enough to run Ubuntu and can run the 32-bit (x86) version; 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. See also https://help.ubuntu.com/9.10/installation-guide/i386/minimum-hardware-reqts.html

Visual Effects

Visual effects provide various optional special graphical effects for your desktop to make it look and feel more fun and easier to use. Even if your computer is powerful enough to run visual effects, you can turn them off and will still have a usable Ubuntu desktop system. Visual effects are turned on by default if you have a GPU (graphics card or integrated chipset) which is supported. Supported GPU manufacturers:

  • ATI (some may require the proprietary fglrx driver)
  • Intel (i915 or better, except GMA 500, aka "Poulsbo")
  • NVidia (with their proprietary driver)

For more information on supported graphics cards, see DesktopEffects.

Ubuntu Server (CLI) Installation

  • 300 MHz x86 processor
  • 128 MiB of system memory (RAM)
  • 1 GB of disk space
  • Graphics card and monitor capable of 640x480
  • CD-ROM drive

See also https://help.ubuntu.com/9.10/serverguide/C/preparing-to-install.html and old spec https://help.ubuntu.com/7.04/installation-guide/i386/minimum-hardware-reqts.html

Lightweight GUI alternative (Xubuntu)

If you have an old or low-spec computer or want to get the most out of your hardware, using a lightweight desktop system such as Xubuntu is recommended, as it should make more efficient use of your system's resources. Of course, even if you have the newest equipment out, you could still use Xubuntu. If your system has less than 192 MB of system memory, use the Alternate Installation CD. Note: If you have a low-specification computer, certain features may be automatically turned off to conserve system resources. For example, if you have a graphics card with only a small amount of video memory (VRAM), the boot-up screen may not be shown. Follow this link for detailed instructions: Installation/LowMemorySystems. Minimum system requirements for Xubuntu would fall roughly between Ubuntu Server and Desktop:

  • 256 MiB of system memory (RAM)
  • 2 GB of disk space
  • Graphics card and monitor capable of 800x600 resolution

Regarding processors, a recent thread on the Ubuntu Forums describes a 500 MHz Xubuntu machine as being "too slow" and discusses alternatives: http://ubuntuforums.org/showthread.php?t=1267443

Ubuntu Netbook Edition

If you have a netbook and a supported graphics card, using Ubuntu Netbook Edition (formerly "Ubuntu Netbook Remix") is an interesting option. It has a nice interface adapted for smaller screens, and a selection of applications aimed at netbook users. Ubuntu Netbook Remix is designed to run well on netbooks with typically minimal specs, i.e.:

  • Intel Atom processor @ 1.6 GHz
  • 512 MiB of system memory (RAM)
  • 4 GB of disk space
  • Screen of 1024x600 resolution
  • Graphics chipset with support for visual effects

LTSP thin-client computers

If you are intending to use a computer as a thin client (such as a client for an Edubuntu LTSP Terminal Server), only a low-specification computer capable of displaying graphics and connecting to a network is required. Follow this link for more information: HowToCookEdubuntu/Chapters/HardwareRequirements.
