Have you seen this already – http://is.gd/kjzr76 ?
The document is available on Google Docs entitled – Gnome 3 System Settings changes. Click on the link above to view it.
In a nutshell what you will see there are changes that have been proposed and are currently being worked on for the next Ubuntu LTS release which is version 12.04 Precise Pangolin. This new LTS comes out end of April 2012. Already 2 Alphas have been released and the upcoming 2 Beta releases are next, if I’m not mistaken.
Among the new things are a new Shutdown dialogue. See the image below. The dialogue will reflect what is enabled under Power Settings, such as Suspend and/or Hibernate, and will not be shown if either or both are disabled. Hibernate will only be enabled by default only for Ubuntu certified hardware. Don’t worry you can force it if you want to. It is included in the options.
On 12.04 we will also be seeing options for the Application Menu to be either integrated to the global menu bar or with the individual windows (which was what used to be pre-Unity). I am sure a lot of people will be happy with this new option. Many people don’t like the global menu bar, especially those with big screens, but on my 1366 x 768 laptop, it is a very welcome feature. It means more screen real estate.
Another great thing that we will see on Precise Pangolin is more options to configure Unity directly from the System Settings. Right now one needs to install CCSM (CompizConfig Settings Manager) in order to do that.
Other interesting things are more options for the Privacy settings and Display Settings which includes support for multi-monitors. Read the document for the entire specifications.
All-in-all Ubuntu 12.04 Precise Pangolin is shaping up quite nicely and I cannot wait to upgrade come April.
