Ubuntu 12.10 (Quantal Quetzal): 8 New Features
Ubuntu 12.10: Now Available for Download
The latest version of Ubuntu, 12.10, is now available for users to download and experience. This release incorporates several refinements and enhancements.
Improvements have been made to the integration of web applications and various online services. Users will also find updates within the Unity interface.
Key Changes and Enhancements
While the changes present in Ubuntu 12.10 aren't revolutionary, they collectively contribute to a more polished user experience. The updates focus on refining existing features rather than introducing entirely new paradigms.
The current feature set is considered incremental. However, anticipation is building for the next major release, Ubuntu 13.04.
Looking Ahead to Ubuntu 13.04
Mark Shuttleworth has indicated that the development team is currently engaged in confidential work on significant new features.
These “tada!” features, as described by Shuttleworth, are being kept under wraps until closer to the release of Ubuntu 13.04. This suggests a more substantial update is planned for the future.
Integrating Web Applications
Ubuntu 12.10 introduced a feature for web app integration, designed to elevate web applications – such as Gmail – to the same level of functionality as native desktop applications.
When browsing a compatible website using either Firefox or Chromium, a prompt will appear offering installation of the web app.
How Web App Integration Works
This functionality allows users to, for instance, pin Gmail directly to their application launcher.
Consequently, a dedicated window for Gmail is created, and new email notifications are displayed within Ubuntu’s messaging menu.
Further details and examples demonstrating the compatibility of this feature with various websites can be found in our dedicated article on Ubuntu’s web app integration.
Managing Online Accounts in Ubuntu
The Online Accounts feature within Ubuntu provides a centralized location for integrating various online services. This allows different applications on your Ubuntu desktop to connect and interact with your accounts seamlessly.
For instance, linking a Flickr account enables you to directly search and preview your photos from the Ubuntu dash. Similarly, connecting a Twitter account will make it accessible within the Gwibber application.
Account Integration Examples
Further integration is possible with other services. Adding an AIM account, for example, will make it available for use in the Empathy instant messaging client.
This centralized approach simplifies the process of connecting your online life to your Ubuntu experience. It streamlines access to your data and services across multiple applications.
By utilizing the Online Accounts control panel, users can efficiently manage their online identities and enhance the functionality of their Ubuntu desktop environment.
Dash Previews
A new functionality has been implemented in Ubuntu’s dash, allowing users to view full-screen previews by simply right-clicking on any item. This applies to various elements within the dash interface.
For instance, a right-click on an application icon will display detailed information regarding that application. This includes a screenshot and, conveniently, an Uninstall button for easy removal.
Preview Functionality Expanded
The preview capability isn't limited to applications. Right-clicking on images or documents will now trigger a preview of the file itself.
This feature provides a quick and efficient way to inspect content without needing to open the application or file directly. It enhances user workflow and accessibility.
Full-Disk Encryption SimplifiedWith Ubuntu 12.10, setting up full-disk encryption has become remarkably straightforward. During the installation process, simply activate the "Encrypt the new Ubuntu installation for security" option. Previously, achieving this level of security necessitated the use of a specialized installation disc.
This differs significantly from home folder encryption, as it secures all files residing on your Ubuntu partition using a password. The system will prompt for this password each time it boots, ensuring data protection.
This functionality is particularly beneficial for laptops and any device storing confidential information. However, it's important to note that encryption can introduce a slight reduction in system performance.
Understanding the Benefits
Full-disk encryption provides a robust layer of security against unauthorized access. Should a laptop be lost or stolen, the data remains inaccessible without the correct decryption key.
The implementation in Ubuntu 12.10 streamlines a process that was once complex. Users can now easily protect their entire system with minimal technical expertise.
- Enhanced data security.
- Simplified setup procedure.
- Protection against physical theft.
While a performance impact is possible, the security advantages often outweigh this consideration, especially for users handling sensitive data. The boot-time password requirement is a small trade-off for comprehensive data protection.
The Consolidation of Unity in Ubuntu
A significant change has occurred within the Ubuntu operating system regarding its desktop environment, Unity. Previously, users encountered two distinct versions of Unity: the standard, 3D-accelerated Unity, and Unity 2D, designed for machines lacking 3D acceleration capabilities.
Despite a visual resemblance, these were fundamentally separate desktop implementations. This distinction has now been eliminated with the unification of the Unity experience.
Removal of Unity 2D
The Unity 2D version has been discontinued. Now, all Ubuntu systems utilize a single, unified Unity desktop environment as the default.
For hardware configurations that do not natively support 3D graphics acceleration, a software rendering solution is employed.
Software Rendering with Gallium3D LLVMpipe
Systems without dedicated 3D graphics hardware will leverage Gallium3D LLVMpipe. This allows Unity’s 3D visual effects to be rendered entirely in software.
This ensures a consistent Unity experience across a broader range of computer hardware, regardless of its graphical capabilities.
The implementation of Gallium3D LLVMpipe maintains the intended visual fidelity of Unity, even on systems where hardware acceleration is unavailable.
Secure Boot Compatibility
Ubuntu 12.10 features a digitally signed Grub 2 bootloader. This enables installation on computers utilizing the UEFI Secure Boot functionality, such as machines running Windows 8.
Installing Ubuntu on these systems doesn't necessitate adding keys to the UEFI firmware, nor does it require disabling Secure Boot.
Understanding Secure Boot
Further details regarding the specifics of Secure Boot can be found in the article, HTG Explains: How Windows 8’s Secure Boot Feature Works & What It Means for Linux.
This resource provides a comprehensive overview of the technology and its implications for Linux distributions.
Driver Management Now Within Software Sources
A notable, though not groundbreaking, change involves the location of driver installation tools. Previously accessible as a standalone application, the Drivers control panel has been consolidated. Users seeking to install proprietary drivers for their computer hardware will now find this functionality integrated directly into the Software Sources application.
Streamlined Driver Installation
This integration simplifies the process of managing and installing closed-source drivers. The Additional Drivers panel is now accessible as a tab within Software Sources.
This change offers a more unified experience for users configuring their systems. It reduces application clutter and centralizes software management tasks.
The functionality remains the same; only the location has been altered for improved usability.
Software Updates in Ubuntu 12.10
As expected, Ubuntu 12.10 incorporates standard updates for all system software components. This includes the Linux kernel version 3.5.4, alongside GNOME 3.6, Firefox 16, and Thunderbird 16.
Furthermore, the update suite features LibreOffice 3.6.2 and a range of other package improvements.
Nautilus File Manager Version
Interestingly, the Nautilus file manager is not utilizing the newest release. Ubuntu continues to employ Nautilus 3.4, rather than the more recent Nautilus 3.6.
The GNOME project implemented several debated modifications within Nautilus 3.6, resulting in the removal of various functionalities, notably desktop icons.
These changes prompted Ubuntu’s decision to retain the earlier Nautilus version for its user base.
Amazon Search Results in Ubuntu
When a search is conducted within Ubuntu, Amazon search results are integrated directly into the dash display. For instance, a search for "Terminal" to open the terminal application may also present options to purchase the film "The Terminal" through Amazon.com.
This functionality can be deactivated if preferred. A comprehensive guide detailing how to disable these Amazon search results is readily available.
Visual Representation
The integration of Amazon results is visually apparent within the Ubuntu dash interface.
