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 64-bit PowerPC (little-endian), this section contains general information and pointers to where additional information can be found.
Ubuntu 18.04 supports six major architectures and several variations of each architecture known as “flavors”. One other architecture (IBM/Motorola PowerPC) has an unofficial port.
|AMD64 & Intel 64||amd64|
|ARM with hardware FPU||armhf||multiplatform||generic|
|multiplatform for LPAE-capable systems||generic-lpae|
|IBM POWER Systems||ppc64el||IBM POWER8 and newer machines|
|IBM z/Architecture||ppc64el||IBM Z and IBM LinuxONE, no s390 (31-bit mode) support||zEC12 and newer machines|
Multiprocessor support — also called “symmetric multiprocessing” or SMP — is available for this architecture. Having multiple processors in a computer was originally only an issue for high-end server systems but has become common in recent years nearly everywhere with the introduction of so called “multi-core” processors. These contain two or more processor units, called “cores”, in one physical chip.
The standard Ubuntu 18.04 kernel image has been compiled with SMP support. It is also usable on non-SMP systems without problems.
Ubuntu's support for graphical interfaces is determined by the underlying support found in X.Org's X11 system, and the kernel. Basic framebuffer graphics is provided by the kernel, whilst desktop environments use X11. Whether advanced graphics card features such as 3D-hardware acceleration or hardware-accelerated video are available, depends on the actual graphics hardware used in the system and in some cases on the installation of additional “firmware” images (see Section 2.2, “Devices Requiring Firmware”).
Details on supported graphics hardware and pointing devices can be found at http://xorg.freedesktop.org/. Ubuntu 18.04 ships with X.Org version 7.7.
Almost any network interface card (NIC) supported by the Linux kernel should also be supported by the installation system; drivers should normally be loaded automatically.
Support for braille displays is determined by the underlying support
brltty. Most displays work under
brltty, connected via either a serial port, USB
or bluetooth. Details on supported braille devices can be found on the
