"The ARMv7 port targets system-on-chips (SoCs) based on ARM's
Cortex-A8 and -A9 processor cores, such as new SoCs from Texas
Instruments, Freescale, and Qualcomm. Ubuntu already supports the
open-source Moblin stack that runs on Intel Atom-based netbooks and
MIDs.
"Ubuntu 9.04 is based on the 2.6.28 Linux kernel, and includes
the new Ext4 filesystem that was introduced in the latest 2.6.29
release. The Ext3 file system is still offered as the default,
however. A new integrated notification system is said to combine
the notification methods of various applications and present the
information "in a simple, unobtrusive manner," says Canonical. The
overall UI, meanwhile, has been gussied up with new icons and
artwork, says the company.
"Other updates include X.org server 1.6, as well as the KDE 4.2
and GNOME 2.26 desktop environments. Gnome 2.26 is touted for
additions, including the Brasero CD burning application (pictured),
and improved handling of multiple monitors with an updated
gnome-display-properties function. The new Ubuntu also offers
version 3.0 of the Microsoft Office-compatible OpenOffice.org."
