Ubuntu 11.04 Natty Narwhal Alpha 2, Released [Screenshots And Video]

Ubuntu 11.04 Natty Narwhal alpha 2 has just been released and as usual, we'll do a recap of all the new features since alpha 1.

Before you proceed to get an detailed view of what's new in Ubuntu 11.04 Natty Narwhal alpha 2, here's a video I've recorded with the latest alpha 2:

Now let's get started.


One of the biggest changes is the replacement of two of the oldest Ubuntu applications: Banshee and LibreOffice have replaced Rhythmbox and OpenOffice:

Libreoffice banshee

Ubuntu 11.04 alpha 2 comes with Kernel 2.6.38 RC2, Server 1.10 and Mesa 7.10, Gnome 2.32.1, Nautilus, Firefox 4.0 beta 10, LibreOffice 3.3.0, Banshee 1.9.2, Evolution 2.32.1.

'200 lines kernel patch' is default in Natty

The Ubuntu 11.04 Natty alpha 2 kernel includes the official inclusion of the '200 line patch' which improves responsivness for some workloads. It also brings a major update to the VFS, RCU dentry handling, which is slated to improve filesystem performance particularly with parallel loads. This kernel brings support for some previously unsupported ACER SD card slots.

The new Server 1.10 and Mesa 7.10 (along with updated drivers) bring support for Sandy Bridge graphics, improved 3D support for newer radeon hardware, support for more OpenGL extensions, improved multi-head functionality, and of course many bug fixes.


One very interesting change since Ubuntu 11.04 Natty Narwhal alpha 1 was made to the AppMenu (Global Menu) which is now hidden in the application window even for unmaximized windows. Here's how it works:
  • when a window is maximized, the application title is displayed on the top panel and the menu shows up when hovering it
  • when an application is not maximized but has the focus, when hovering its title on the top panel, only part of its title is displayed so you know to which application that menu belongs to (yet its title doesn't get in the way)

Here are some screenshots to get a better idea:

This behavior can also be seen in the video in the beginning of the post.

Unity launcher / places

The Unity Launcher now supports intellihide (which has been set as default). To bring the launcher when an application is in full-screen you can press the Super key or mouse over the Ubuntu logo in the top left corner. Also, there are some new experimental Unity options: Backlight always on, launch animation (pulse until running and blink) and urgent animation (wiggle and pulse):

Unity Places Files / Applications is back in Unity, though not fully functional for now:

Ubuntu Software Center got ratings and reviews support:

You need an Ubuntu single sign-on to be able to rate an application.

Another very interesting recent feature is tiling which you can achieve by dragging a window to the left/right edge of the screen. When dragging the window back, it comes back to the initial size. If you drag a window to the top edge of the screen, it will maximize:

The Ubuntu Sound Menu now supports playlists:

Unity also got a "Places Tile View" which is broken in the latest Alpha 2, but it should return soon:

Ubuntu One has a new look:

The Classic Ubuntu desktop got some changes too (this is the fallback for those running computers that don't support Unity): the "Menu Bar" has been replaced with the "Main Menu" applet and AppMenu (Global Menu) is now default for the classic interface too:

Grub2 finally got BTRFS support!

The BTRFS Launchpad blueprint states that BTRFS now supports Grub2 and that it got compression support (however I didn't test this).

However, the work on BTRFS is not done. Here's a list of things that still need work:
  • investigate integration with the release upgrader
  • investigate snapshot integration with apt's dpkg::pre-install-pkgs hook
  • investigate UI options for easy revert after upgrade
  • provide UI to discard snapshot after upgrade to save space
  • automatically revert to snapshot on upgrade error

Unity 2D (Qt)

Unity 2D Qt

A Unity Qt/QML port was recently released which is supposed to be available as an option for those who do not have the necessary hardware to run the regular Unity ("3D"). However, Unity 2D won't be available on the Ubuntu 11.04 Natty Narwhal CD. Instead, a classic desktop (Gnome panels) will be available as a fallback for those with old hardware, as you've read above. This however has not been 100% decided!

AT&T MiFi 2372 review

In the week or so that I have been testing the AT&T MiFi 2372 by Novatel Wireless, it has already saved no less than three lives. First, it saved my cable guy’s life. You see, Time Warner Cable provides the worst home Internet service I have ever experienced. I can’t even think of a close second. If providing terrible home Internet service was a sport, Time Warner Cable would be on its tenth consecutive undefeated season. Forget the fact that my upload speed is capped at 60Kbps and I’m lucky if I can get half that — it has been months since I’ve gone through a full day without at least one service interruption. Months. Unfortunately, Time Warner Cable has an exclusive contract with my building so I have no choice but to endure its abysmal service. Last week, as a Time Warner Cable technician entered my home for the sixth time in two months, I realized that this certainly would have spelled serious trouble had it not been for my trusty new back up device. Before the Mi…
