Since a lot of people want to upgrade to Ubuntu 11.04 Natty Narwhal already, I though you'd like to see a video (well actually 2) on how to upgrade to Ubuntu 11.04. Remember that starting with Ubuntu 11.04, you can upgrade using the Live CD too.

In the above Unity video you'll notice:

The "ubuntu-wallpapers" package has just been updated in Ubuntu 11.04 Natty Narwhal and it now includes wallpapers from the Ubuntu 11.04 community contest:

After many comments about it, I've decided to make a separate post as it seems everybody wants to know what theme this is even though there was an announcement on ppa.webupd8.org.

The Nautilus Elementary project was shut down in November in favor of Marlin - a new file manager, but many people are still using Nautilus Elementary so ammonkey, the Nautilus Elementary developer decided to bring it back to life and update it to version 2.32.2 for both Ubuntu 10.10 Maverick Meerkat as well as for Ubuntu 11.04 Natty Narwhal:

The beautiful Faenza Icon Theme was updated to version 0.9 today, bringing a new "darkest" theme with status and action icons in light grey.

Here's the complete Faenza Icon Theme 0.9 changelog:

Firefox 4 (stable) will be released soon and I though I'd let you know how to install it in Ubuntu 10.04 and 10.10 - the proper way.

* 0 AD is a historical real-time strategy open-source game.

* Red Eclipse is a single-player and multi-player first-person ego-shooter, built as a total conversion of Cube Engine 2, which lends itself toward a balanced gameplay, with a general theme of agility in a variety of environments

A New Start is a beautiful theme pack that was updated a few days ago. This is not just a GTK / Metacity theme - it comes with many customizations: Conky configuration, a coverGloobus theme, fonts, an AWN theme, Gnome panel and AWN backgrounds and even a Firefox Startpage.

Remember the "2 sided Unity dock" mockups we've posted last week? Well, Andrea Azzarone (who's patch is also responsible for bringing configurable icon size for the Unity dock), has turned one of the 2 sided Unity docks mockups to reality and you can see it in action in the video below:

Last week we saw how to install Sparkleshare in Ubuntu from a PPA. As a reminder:

Sparkleshare is a tool to synchronize your files in the cloud - like Dropbox or SpiderOak - but unlike these, Sparkleshare is open source and allows you to use your own server. Sparkleshare uses GIT so if you delete/modify some files by accident, you can easily revert the changes.

Ubuntu 11.04 Natty Narwhal will get overlay scrollbars but for now the packages that provide this are available in a PPA and further more, you must use "export LIBOVERLAY_SCROLLBAR=1" when launching an application to get overlay scrollbars.

Remember Borderless Elementary? It was quite a success and I'm not sure if that's where the Ubuntu devs got the idea from, but update today in Ubuntu 11.04 removes the borders for the Ubuntu "Light" themes:

Unity 3.6.4 was uploaded to the Ubuntu 11.04 Natty Narwhal repositories a few minutes ago, brining some features many of you were waiting for. Read on!

Sparkleshare is a tool to synchronize your files in the cloud - like Dropbox or SpiderOak - but unlike these, Sparkleshare is open source and allows you to use your own server. Sparkleshare uses GIT so if you delete/modify some files by accident, you can easily revert the changes. You can use it with your own server, GitHub or Gitorious.

There's a long thread on the Ayatana mailing list about the upper-left Ubuntu button in the upcoming Ubuntu 11.04. Currently, this button will open Dash. But there are also two shortcuts in the launcher which trigger Dash (Applications / Files Places) which make the Ubuntu button redundant - this lead to some new ideas for the upper-left Ubuntu button behavior.

2 quick updates in the WebUpd8 PPAs:

gThumb is an image viewer and photo manager for GNOME. It comes with options to edit photos, transfer photos from digital cameras and upload photos to popular websites such as Facebook, PicasaWeb, Photobucket, Flickr and more.

If you like how Chrome displays the window controls (close, minimize and maximize buttons) next to the tabs and want this in Firefox, you'll be glad to know it's quite easy to achieve.

Mark Shuttleworth has just announced the codename for the Ubuntu version after Natty - Ubuntu 11.10 will be codenamed "Oneiric Ocelot".
