Ubuntu does not impose hardware requirements beyond the requirements of the Linux kernel and the GNU tool-sets. Therefore, any architecture or platform to which the Linux kernel, libc, gcc, etc. have been ported, and for which an Ubuntu port exists, can run Ubuntu.
Rather than attempting to describe all the different hardware configurations which are supported for AMD64, this section contains general information and pointers to where additional information can be found.
Ubuntu 10.04 supports three major architectures and several variations of each architecture known as “flavors”. Three other architectures (HP PA-RISC, Intel ia64, and IBM/Motorola PowerPC) have unofficial ports.
| Architecture | Ubuntu Designation | Subarchitecture | Flavor |
|---|---|---|---|
| Intel x86-based | i386 | ||
| AMD64 & Intel EM64T | amd64 | ||
| HP PA-RISC | hppa | PA-RISC 1.1 | 32 |
| PA-RISC 2.0 | 64 | ||
| Intel IA-64 | ia64 | ||
| IBM/Motorola PowerPC | powerpc | PowerMac | pmac |
| Sun SPARC | sparc | sun4u | sparc64 |
| sun4v |
Complete information concerning supported peripherals can be found at Linux Hardware Compatibility HOWTO. This section merely outlines the basics.
Laptops are also supported and nowadays most laptops work out of the box. In case a laptop contains specialized or proprietary hardware, some specific functions may not be supported. To see if your particular laptop works well with GNU/Linux, see for example the Linux Laptop pages.
Multiprocessor support — also called “symmetric multiprocessing” or SMP — is available for this architecture. The standard Ubuntu 10.04 kernel image has been compiled with SMP-alternatives support. This means that the kernel will detect the number of processors (or processor cores) and will automatically deactivate SMP on uniprocessor systems.
You should be using a VGA-compatible display interface for the console terminal. Nearly every modern display card is compatible with VGA. Ancient standards such CGA, MDA, or HGA should also work, assuming you do not require X11 support. Note that X11 is not used during the installation process described in this document.
Ubuntu's support for graphical interfaces is determined by the underlying support found in X.Org's X11 system. Most AGP, PCI and PCIe video cards work under X.Org. Details on supported graphics buses, cards, monitors, and pointing devices can be found at http://xorg.freedesktop.org/. Ubuntu 10.04 ships with X.Org version 7.5.
Almost any network interface card (NIC) supported by the Linux kernel should also be supported by the installation system; modular drivers should normally be loaded automatically. This includes most PCI and PCMCIA cards.
ISDN is supported, but not during the installation.
Wireless networking is in general supported as well and a growing number of wireless adapters is supported by the official Linux kernel, although many of them do require firmware to be loaded. Wireless NICs that are not supported by the official Linux kernel can generally be made to work under Debian GNU/Linux, but are not supported during the installation.
The use of wireless networking during installation is still under development and whether it will work depends on the type of adaptor and the configuration of your wireless access point. If there is no other NIC you can use during the installation, it is still possible to install Debian GNU/Linux using a full CD-ROM or DVD image. Select the option to not configure a network and install using only the packages available from the CD/DVD. You can then install the driver and firmware you need after the installation is completed (after the reboot) and configure your network manually.
In some cases the driver you need may not be available as a Debian package.
You will then have to look if there is source code available in the internet
and compile the driver yourself. How to do this is outside the scope of this
manual.
If no Linux driver is available, your last resort is to
use the ndiswrapper package, which allows you to use
a Windows driver.
Linux supports a large variety of hardware devices such as mice, printers, scanners, PCMCIA and USB devices. However, most of these devices are not required while installing the system.
USB hardware generally works fine, only some USB keyboards may require additional configuration (see the section called “Hardware Issues to Watch Out For”).
Again, see the Linux Hardware Compatibility HOWTO to determine whether your specific hardware is supported by Linux.
