How To Upgrade Linux Kernel on Supported Ubuntu Releases and Its Derivatives To Ububntu 16.04 's Kernel (linux 4.4.X)
You may know that we can get latest stable kernel on Ubuntu from point release( or
LTSEnablementStack) which is released by Ubuntu for every 6 moths.
The Ubuntu LTS enablement stacks provide newer kernel and X support for existing LTS releases. These can be installed manually, or are automatically shipped if installing from point releases like.. 12.04.2/14.04.2 and newer release media.
Brand new hardware devices are released to the public always more frequently. And we want such hardware to be always working on Ubuntu, even if it has been released after an Ubuntu release. Six months (the time it takes for a new Ubuntu release to be made) is a very long period in the IT field. Hardware Enablement (HWE) is about that: catching up with the newest hardware technologies.
The 12.04.x , 14.04.x and newer point release will ship with an updated kernel and X stack by default. If you have installed with older media you can use the following to install the newer HWE kernel derived from Ubuntu 16.04 (XenialXerus):
Now run the following command to install linux kernel 4.4 which is provided by Ubuntu as HWE stack
sudo apt-get install linux-generic-lts-xenial
Now package manager will ask for your confirmation ..that whether you want to continue or you want to abort installation process..
So, give Y (yes) and press Enter
That's it ,,, Now you have system installed with 16.04 's kernel (Linux kernel 4.4)
If you encounter any issues after installing this kernel .. you can easily un-install this kernel.
Run the following command to un install the kernel that you have installed just before.
Screen Shot : Ubuntu 16.04 launcher moved to bottom of the screen
Ubuntu 16.04 ( Xenial Xerus ), the next major/LTS(Long Term Release) of Ubuntu, is set for its stable release on Thursday April 21, 2016. And here, What's new in the next major version of world's most linux distribution. share it , with fellow linux fans and enjoy !!
New features in 16.04 LTS
Though we already know that this new release is not bringing a big UI changes to Unity Desktop.. It's worth to mention.. that ... Ubuntu 16.04 finally lets you move the Unity launcher to the bottom of the screen - nearly six long years after user's first asked. And you have the Ubuntu Kylin team to thank for it for it is they who did the heavy work of hacking Unity to be moveable.

While the 'option' to change position is buried deep in the geeky depths of dconf-editor it is the one change that everyone is talking about. But it's not the only welcome improvement.
Updated Packages
As with every new release, packages--applications and software of all kinds--are being updated at a rapid pace. Many of these packages came from an automatic sync from Debian's unstable branch; others have been explicitly pulled in for Ubuntu 16.04.
Linux kernel 4.4
This beta of Xenial ships with Linux kernel 4.4, with the following highlights:
Improved Intel Skylake processor support
3D support in the virtual GPU driver
New driver for Corsair Vengeance K90
Support for TPM 2.0 chips
Journaled RAID 5 support
Linux Kernel 4.4 also includes less obvious changes including bug fixes and improvements for various file systems, power efficiency, and memory management.

Core Application Updates
A batch of updates to Ubuntu applications are also included. Among them you'll find:
As is to be expected, with any release, there are some significant known bugs that users may run into with this release of Ubuntu 16.04. The ones we know about at this point (and some of the workarounds), are documented here so you don't need to spend time reporting these bugs again:
Boot, installation and post-install
Errors about swap partition at install
There is a known issue regarding the creation of swap space during the install. In some cases the install will display the error message "Creation of swap space in Partition #n .... failed.". Please see this https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1552539 for more information. You may work around the issue by manually partitioning the disk and removing any existing swap partitions before then creating a new one.
Upgrade
14.04 LTS to 16.04 LTS Desktop Upgrade
There is a known issue which prevents the upgrade of 14.04 LTS to 16.04 LTS. Please see this bug for more information.
At this time you should not attempt to upgrade a production desktop from 14.04 LTS to 16.04 LTS.
Amazingly, there is only one known major bug in the release. Conrad explains, "in some cases, attempts to install to a hard drive that already contains a swap partition may fail in the partitioning phase. If you encounter this, the simplest workaround is to boot to the live session, start a terminal (Ctrl-Alt-T) and type 'sudo swapoff -a'. You can then start the installation from the icon on the desktop and it should proceed successfully".
Graphics and Display
fglrx
The fglrx driver is now deprecated in 16.04, and we recommend its open source alternatives (radeon and amdgpu). AMD put a lot of work into the drivers, and we backported kernel code from Linux 4.5 to provide a better experience.
When upgrading to Ubuntu 16.04 from a previous release, both the fglrx driver and the xorg.conf will be removed, so that the system is set to use either the amdgpu driver or the radeon driver (depending on the available hardware).

Download Ubuntu 16.04 Beta 2
Beta releases of Ubuntu are not for everyone. If you need a stable system, hate bugs and can’t deal with potential package breakages, wait for the stable release next month.
And if you are keen to try it out stick to running it off of a live USB or DVD. Also note that there is a major bug that may cause beta installs to fail on hard-drives which already contain a swap partition.

The new release means , the much more new features and bug fixes. And also Linux Kernel 4.4 is an LTS(Long Term Support) version and more stable release.
Now , Here I am going to show how to install Linux kernel 4.4 rc4 in Ubuntu and Ubuntu based systems using official ppa. it is official ppa of Ubuntu kernel ,so we will get updates from Ubuntu.
Now you can install linux kernel 4.4 on ubuntu and it's derivatives more easily through Ubuntu's HWE(Hardware Enablement) release
Step 1 :
Open The Terminal (press Ctrl+Alt+T )
Step 2
Update Your System's Source List
sudo apt-get update
Step 3 :
Now run the following command to install linux kernel 4.4 which is provided by Ubuntu as HWE stack
sudo apt-get install linux-generic-lts-xenial
Now package manager will ask for your confirmation ..that whether you want to continue or you want to abort installation process..
So, give Y (yes) and press Enter
That's it ,,, Now you have system installed with 16.04 's kernel (Linux kernel 4.4)
If you encounter any issues after installing this kernel .. you can easily un-install this kernel.
Run the following command to un install the kernel that you have installed just before.
Linux kernel 4.4 LTS (Long-Term Support) was officially released by Linus Torvalds and his team of developers on 10 January.
Prominent features of Linux kernel 4.4 LTS include 3D support in the virtual GPU driver, allowing for 3D hardware-accelerated graphics in virtualization guests, a leaner and faster loop device that supports Asynchronous I/O and Direct I/O, thus increasing the system's performance and saving memory, and support for Open-Channel Solid State Drives (SSDs) through LightNVM.
Furthermore, Linux kernel 4.4 LTS adds journaled RAID5 MD support, fixing the RAID write hole, and perf and eBPF integration, allowing unprivileged users to run persistent eBPF programs. Also worth mentioning are Block polling support for improving the overall performance of high-end storage devices, a brand new mlock2() syscall for locking memory on page fault, and fully lockless handling of the TCP listener, allowing for more scalable and faster TCP (Transmission Control Protocol) servers.
"Nothing untoward happened this week, so Linux-4.4 is out in all the usual places.The changes since rc8 aren't big," says Linus Torvalds. "There's about one third arch updates, one third drivers, and one third 'misc' (mainly some core kernel and networking), But it's all small. Notable might be unbreaking the x86-32 'sysenter' ABI, when somebody (*cough*android-x86*cough*) misused it by not using the vdso and instead using the instruction directly."
In addition to the awesome new features introduced in today's release of Linux kernel 4.4 LTS, we can notice a lot of updated drivers, as well as the addition of new ones, which will make the kernel support even more modern hardware components and all sorts of devices. Linux kernel 4.4 LTS ships, of course, with lots of under-the-hood improvements and countless bugfixes. More details can be found in Mr. Torvalds announcement. you can read more intresting article @ Linux Planet
