2.1. Supported Hardware

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.

2.1.1. Supported Architectures

Ubuntu 5.04 supports eleven major architectures and several variations of each architecture known as 'flavors'.

2.1.2. Graphics Card

Ubuntu's support for graphical interfaces is determined by the underlying support found in X.Org's X11 system. The newer AGP video slots are actually a modification on the PCI specification, and most AGP 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 5.04 ships with X.Org version 6.8.1.

2.1.3. Multiple Processors

Multi-processor support — also called ``symmetric multi-processing'' or SMP — is supported for this architecture. However, the standard Ubuntu 5.04 kernel image does not support SMP. This should not prevent installation, since the standard, non-SMP kernel should boot on SMP systems; the kernel will simply use the first CPU.

In order to take advantage of multiple processors, you'll have to replace the standard Ubuntu kernel. You can find a discussion of how to do this in Section 8.4, “Compiling a New Kernel”. At this time (kernel version 2.6.10) the way you enable SMP is to select ``symmetric multi-processing'' in the ``General'' section of the kernel config.
