How to Install New Kernel on Ubuntu

How to install Linux Kernel 3.4 in Ubuntu 12.04. WARNING This isn't worth doing unless you're having problems with the old kernel or you're adding new hardware which is unsupported in old Kernel 3.2, such as nVidia Kepler (600 series) or AMD HD 7000 series Graphics cards.

Improvements in Kernel 3.4:
Reduced Power Usage
Speed improvements for BTRFS file systems
More wireless network drivers from Ralink and Broadcom added
Support for nVidia Kepler chipsets (600 series)
Support for AMD Southern Islands GPUs (HD 7000 series)
Support for AMD Trinity Processors

Ubuntu Kernel Website: http://kernel.ubuntu.com/~kernel-ppa/mainline/
Look for the latest Kernel
Download linux-headers-3.4.x-xxx-all.deb, plus the headers and image for your system architecture.
e.g. linux-headers-3.4.x-xxx-i386.deb, and linux-image-3.4.x-xxx-generic-i386.deb for 32bit systems.

Open Terminal
cd ~/Downloads
sudo dpkg -i linux*.deb

Reboot
Check the new kernel is running with either System Monitor or "uname -r"

If you have any problems with the new kernel reboot and select "Previous Versions" on the Grub Menu (hold down Shift key if Grub doesn't show by default)

Remove auto updating old Kernel:
In Synaptic remove: linux-generic, linux-headers-generic, linux-image-generic
You can also remove any older kernels to free up some harddrive space.
