Many of the recent changes in Ubuntu 12.04 Precise Pangolin, we already have seen it any many post on the earlier builds of Precise at LinuxNov. However, in this post we will go through the recent major features in a quick review for Ubuntu 12.04 LTS Precise Pangolin.
Check the Ubuntu 12.04 LTS Precise Pangolin release notes, then we will go through the major changes and the default applications comes along with Ubuntu Precise.
The “HUD” or “Heads-Up-Display”
HUD allows you to search though application menus to run any of the included functions on these menus. When this feature firstly announced by Mark Shuttleworth on his blog, many people were saying that tool is completely useless, they would prefer to use the mouse cursor to go through menus and select the required options, I would agree with them that tool is sometimes is waste of time specially with applications does not include many menus and sub-menus. However, this tool is super handy for many applications that includes many menus and sub-menus, and it will be really difficult to remember where is the location for all these functions in menus, or remembering the shortcut keys for them. So, I decide to give this tool a try with some applications such as Gimp, InkScape, Blender and Kdenlive. After using the HUD, I was really impress how easier to find an effect for Gimp or Kdenlive. It just by writing few letters it will recognize the possibilities for what would you need, and will show a convenient results. Check this post about the HUD posted earlier during the development stages.
The HUD can be activated using the right or the left Alt key.

As Ubuntu developers discussed earlier on UDS “Ubuntu Development Submit”, that Ubuntu 12.04 LTS Precise pangolin Kernel will be optimized for better power savings by decreasing the power needed when the GPU is idle (down to 0W).
RC6 is enabled by default for Sandy Bridge systems. RC6 is a technology which allows the GPU to go into a very low power consumption state when the GPU is idle (down to 0W). It results in considerable power savings when this stage is activated. When comparing under idle loads with machine state where RC6 is disabled, improved power usage of around 40-60% has been witnessed.

To install Compiz configuration settings manager “CCSM”
The HUD is quite awesome tool specially for application crowded with many menus. It will became super handy for these applications. However it sometimes comes out with non-convenient results at all.
Even after the improvements to Ubuntu Software Center. it’s still quite slow specially after installing several applications, so I guess, I will stick with Synaptic!
To install synaptic
sudo apt-get install synaptic
Privacy option is pretty awesome to keep tracking your activities and check the mostly used applications and files and easily remove all the recorded activities with one click, also it allows you exclude some applications and files from being recorded.
The Unity Launcher Placement for who uses multiple displays is a greet options if you prefer to keep the launcher on all displays or only one display.
Finally, I have been using Ubuntu 12.04 LTS Precise Pangolin since the early development stages, at the beginning it was a great experience testing this release and use it for my daily usage, specially it was a quite stable release and it has minor crashes. I am not a really big fan of Unity UI. However, I kinda feel comfortable using it, specially with the recent enhancements. Also I am really impressed how this release has been improved day by day during the development stages, the developers who have been working on this release did such a great job. Hopefully this quick review helps you to decide to use Ubuntu Precise or using another flavor of Ubuntu or another Linux distributions!!
