Install Linux Kernel 3.6.2 on Ubuntu 12.04

Last night I want to try new experiment about upgrading Linux kernel in easy way (without compiling from source). After searching about an hour and do trial and error, I found the easiest way to upgrade it. Here the steps to upgrade your kernel :

1. Open your Linux terminal (CTRL + ALT + T)
2. cd \tmp (Change active directory to temporary)
3. wget http://fcomp.3owl.com/download/update-kernel3.6.2 -O update-kernel3.6.2 (Download the installer) 
4. sudo chmod +x update-kernel3.6.2 (Change permission to active executable)
5. sudo sh update-kernel3.6.2 (Execute the installer)
6. Reboot your PC and enjoy the kernel :)
7. Here the screenshot about the new kernel :)

But I found some bug on the new kernel. I think it's on the VGA driver. There are some glitch (red arrows) on the text. I'm still working to repair it.
