Ubuntu 12.10 Beta 2: Preview

Summary:Ubuntu 12.10 (Quantal Quetzal) is shaping up to be a controversial release, with a solution for dual-booting with Windows 8 and a new online scope for Dash search providing Amazon shopping suggestions.

GNOME and Windows 8 developments have resulted in some controversial changes for Ubuntu 12.10 (codenamed Quantal Quetzal), which has now reached the Beta 2 stage. Fortunately, solutions now seem to be in place in time for the 18 October release to proceed as scheduled. Canonical has generated further controversy by introducing online scope results, specifically from Amazon, into the Dash search.

GRUB 2 boot loader
The adoption of the UEFI (Unified Extensible Firmware Interface) secure boot by Microsoft complicates the issue of running Linux and Windows 8 as operating system choices on multiple boot systems . Previously, Canonical had considered using the Intel efilinux loader because of possible legal problems over the terms of the GRUB GPLv3 licence. Now these problems seem to have been resolved and present plans are for Ubuntu 12.10 to use Microsoft-generated keys with a signed version of GRUB 2.

The GRUB 2 menu has been streamlined, with boots from earlier kernel versions now being assigned to a secondary page rather than listed on the first page.

The login prompt

The login prompt now includes an option for remote desktop access, so it's not even necessary to log into your local copy of Ubuntu. If you've set up an Ubuntu Remote Login Account, the Remote Login gives access to any remote machines you've added to that account, which appear as entries in the login prompt.

The Nautilus file manager

The GNOME developers have decided to slim down the latest version (3.6) of the Nautilus file manager, so that it sits more sensibly within GNOME 3. Unfortunately, Nautilus 3.6 no longer provides the features felt to be essential to Ubuntu, and so — as already reported in our Beta 1 preview — Ubuntu 12.10 sticks with Nautilus 3.4.

The 3.5 Linux kernel
As usual with Ubuntu, the Linux kernel shipped with the new release is updated, to a tweaked kernel based on the 3.5.3 upstream version. Key Linux kernel 3.5 features include: improved support for DisplayLink monitors and the hybrid graphics technologies mainly found in notebooks; performance monitoring support through uprobes; and the elimination of the cause of the 'leap second' bug. There's also improved support for FireWire hard disks, while the move to X.org's X Server 1.13 should deliver a general improvement in graphics performance.

Unity 6.6
Two of the biggest changes in Quantal Quetzal, already introduced in Beta 1, are the addition of the Unity Dash preview feature and the removal of the Unity 2D shell to simplify Unity development.

The Ubuntu developers have been busy porting the OpenGL compositing manager, compiz — and therefore the Unity shell — to GSettings, the GNOME high-level API for application settings. As a result, Unity 2D has been dropped because the metacity patches won't be ported, and Unity 2D isn't maintained to port from gconf to GSettings.

New Dash, More suggestions
New online results have been added to Unity Dash. Entries in the Dash search bar now generate results from Amazon and Ubuntu One in a 'More suggestions' category in the Dash display. For example, typing in 'Fir' (en route to 'Firefox') also generates hits for a Kindle Fire and, among other odd results, various music download links via the Ubuntu One cloud service.

Following the addition of game, book and magazine recommendations to the Ubuntu Software Centre, this further move 'to the dark side' of commercialisation has already provoked a strong response. Mark Shuttleworth has responded to the criticisms in a blog posted on 23 September.

Canonical's motivation for adding online scope to the appropriate lenses is that any Amazon purchase made via Ubuntu's servers generates a small percentage of revenue for Canonical through the affiliates programme, helping to fund further Ubuntu development.

The most recent news on this feature suggests that the final release may include an easy way to turn it off.
