- title Ubuntu System Requirements
<
>
This page details the hardware required to run Ubuntu and/or its KDE derivative Kubuntu, as well as other versions.
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.
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.

Desktop installation
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.
Bare Minimum requirements
It should be possible to get Ubuntu running on a system with the following minimum hardware specification, although it is unlikely that the system would run well. You should use the Alternate install CD to attempt such an installation.
- 300 MHz x86 processor
- 64 MB of system memory (RAM)
- At least 4 GB of disk space (for full installation and swap space)
- VGA graphics card capable of 640x480 resolution
- CD-ROM drive or network card
Recommended minimum requirements
Ubuntu should run reasonably well on a computer with the following minimum hardware specification. However, features such as visual effects may not run smoothly.
- 700 MHz x86 processor
- 384 MB of system memory (RAM)
- 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 visual effects
Visual effects provide various special graphical effects for your desktop to make it look and feel more fun and easier to use. If your computer is not powerful enough to run visual effects, you can turn them off and will still have a usable Ubuntu desktop. Visual effects are turned on by default if you have a graphics card which is supported. For information on supported graphics cards, see DesktopEffects.
- 1.2 GHz x86 processor
- 384 MB of system memory (RAM)
- Supported graphics card (see DesktopEffects)
Lightweight 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. Please remember that the (minimum) requirements here are only directional. You might be able to install Xubuntu on systems with less RAM, but in these cases the performance will be greatly degraded. If your specifications are lower than the minimum requirements but you still want to install Xubuntu in your machine, please consider using pre-8.04 releases (preferably try 7.10 first and go to 6.06 (LTS) if you can't get it working).
Bare Minimum requirements
- 300 MHz processor
- 192 MB of system memory (RAM)
- At least 1.5 GB of disk space
- VGA graphics card
Recommended minimum requirements
- 700 MHz processor
- 256 MB of system memory (RAM)
- 6 GB of disk space
- Graphics card capable of 800x600 resolution
Netbook alternative (Ubuntu Netbook Remix)
If you have a netbook and a supported graphics card, using 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. Because the launcher uses OpenGL, your graphics card needs to be fully supported under Ubuntu in order to run smoothly.
Supported graphics cards
- ATI cards (R6xx/R7xx may require the proprietary fglrx driver)
- Recent Intel cards (i915 or better, except GMA 500 / Poulsbo / SCH)
- NVidia cards with the proprietary NVidia driver
Recommended minimum requirements
Ubuntu Netbook Remix should run reasonably well on a computer with the following minimum hardware specification.
- 700 MHz x86 processor
- 384 MB of system memory (RAM)
- 6 GB of disk space
- Graphics card capable of 800x600 resolution and 3D (OpenGL)
- Sound card
- A network or Internet connection
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.
Absolute minimum installation
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
