Ubuntu 12.04 precise pangolin is expected to be releasing tomorrow, sources confirmed that 12.04 LTS is coming with loads of new features along with a fresh Kernel.

The Head Up Display or HUD is the prime change in Upcoming 12.04 LTS

HUD is a new way to quickly search and access any desktop application’s and indicator’s menu,” HUD can be accessed by pressing the Alt key and typing in a description of what you want to do. The software will then return a set of corresponding entries, including some fuzzy matching, the project team says. Over time, it also learns from your previous choices to make the search more and more accurate.

Power Savings

Definitely power saving is the important change after HUD. 12.04 enabled with RC6--the technology that allows GPUs to go into a very low power consumption state when the GPU is idle--is now enabled by default for Sandy Bridge systems. The result can be improvements of between 40 and 60 percent in power usage under idle loads.

Clickpad or Trackpad support

Ubuntu 12.04 now includes support for ClickPads, On which the physical button is integrated into the trackpad surface. Coming in Ubuntu's next release will be support for Apple Magic Trackpads and more devices, the Ubuntu team says.

Improved language support

When users install new software through the Ubuntu Software Center, the corresponding language support packages--including translations and spell check modules--are now installed automatically as well. reduces user effort to install them manually after software installation.

New Kernel

Stable release of Precise Pangolin,  includes the 3.2.0-17.27 Ubuntu kernel, which is based on version 3.2.6 of the upstream stable Linux kernel.

[Solved] Ubuntu 12.04 blinking screen on startup

After installing Ubuntu 12.04 beta version, if you are getting a blinking screen, probably it will be the problem with hardware. it is advised to choose try ubuntu before installing it to check whether the OS is working without any problem.


try the following steps if you are facing this issue. 


nomodeset, which is needed for some graphic cards that otherwise boot in to a black screen or corrupted splash, acpi_osi= to fix lcd backlight and other problems, and noapic and nolapic to work around various ACPI BIOS issues. In this how to I will explain briefly what this is and how to do it. 


nomodeset
The newest kernels have moved the video mode setting into the kernel. So all the programming of the hardware specific clock rates and registers on the video card happen in the kernel rather than in the X driver when the X server starts.. This makes it possible to have high resolution nice looking splash (boot) screens and flicker free transitions from boot splash to login screen. Unfortunately, on some cards this doesnt work properly and you end up with a black screen. Adding the nomodeset parameter instructs the kernel to not load video drivers and use BIOS modes instead until X is loaded. 

Note that this option is sometimes needed for nVidia cards when using the default "nouveau" drivers. Installing proprietary nvidia drivers usually makes this option no longer necessary, so it may not be needed to make this option permanent, just for one boot until you installed the nvidia drivers.

acpi_osi=
This option frequently solves problems with LCD backlight, fan control problems and misreporting of thermal events. What I understand it does (but corrections are welcome), is prevent the kernel from reporting to the bios that its any windows version the bios asks for. By default, the kernel pretends to be all windows versions, that way we are certain the bios executes all the code needed to initialize the hardware. Unfortunately, some bioses contain fixes to fix problems with specific windows versions (notably vista) that arent needed or dont work for other OS's. Setting

Code:

acpi_osi=

(nothing behind the = sign) as boot option makes the kernel not respond to osi queries.

If the bios has provisions for Linux, you can also try

Code:

acpi_osi="Linux"

Or you can try 

Code:

acpi_osi="Windows 2006"

To make the kernel pretend its vista and make the bios execute routines on machines that require them.

acpi=off
This disables ACPI completely. 
Note: this may not work with all computers and will disable a lot of useful (or even needed) features. In some cases it may even disable some crucial features, like.. fans. Be careful with this option, it might cause your machine to overheat if the fans no longer turn. Think of this as a last resort. Also note some machines requireacpi=ht instead.

Noapic and nolapic
noapic and nolapic kernel options instruct the kernel to not use certain programmable interrupt controllers. To understand what that means exactly requires a deep knowledge of PC hardware, I will not go in to that here, Ill limit myself to saying on some bioses, especially for older systems, there are problems in the implementation of this and it may be necessary to disable either or both to cure a wide range of obscure problems, often but not always related to keyboard and mouse and power management (standby/resume issues).

vmalloc=xxxM 
In some cases kernel drivers can not be loaded due to a lack of virtual addressing space on 32 bit systems. Logs will show errors like. 

Code:

allocation failed: out of vmalloc space - use vmalloc=<size> to increase size.

thanks for p4man who explained this here.

Ubuntu is all set to go Mobile: Ubuntu for android

This time ubuntu stunned the mobile world by announcing a future concept of carrying a desktop within your very smart android phone.

A full Ubuntu desktop, on your docked Android phone thats what ubuntu desktop for android. which means ubuntu is ready to launch their solution for android phones, which enables a powerful android phone a desktop when docked. a keyboard and mouse duo can also be associated with this andro ubuntu desktop. why  carry two devices when you can do it all with your dual core android phone.

Canonicals words about the new venture. "we’ve brought Android together with Ubuntu, the world’s favourite free operating system, to give you a full productivity desktop that fits in your pocket. Android for the phone experience, Ubuntu for the desktop, all on one device, running at the same time."

 So forget the office PC. Just dock your corporate phone and enjoy Ubuntu. Anywhere. One address book. One set of bookmarks. One place for your text messages and email. No more typing on a tiny screen when all you want is a keyboard and a mouse. Seamless integration of your desktop and mobile worlds. Brilliant.

Users will want at least one dock, complete with monitor, keyboard and mouse. Many will want two of each - one for the office and one for the home. And mobile users will opt for clamshell devices that give them a laptop experience whenever they need it - on the train, on the plane or in meetings.

Desktop productivity goes well beyond the keyboard, monitor and mouse. Imagine projectors with a phone dock built in, so you can carry less to your presentations. And imagine TVs that become home PCs when you dock your phone: perfect for the emerging market where LTE will be the normal way for new users to connect to the Internet.
