How to install Kernel 3.0.0-8 in Pinguy OS 11.04.1
I have seen a few places post about installing the Kernel thats in Oneiric to be able to run Kernel 3.0 on 11.04. You can grab the Kernel packages for Oneiric from here (you will need to grab all 3 packages for your architecture. The 2 headers and image package). Its still very buggy and unusable. It is newer then the version I am going to show you how to install but for now I would skip that version. There is no harm if you decide to try it as you can always fall back to the working Kernel, I just doubt you are going to get much millage out of it.
Before you decide to go ahead and install Kernel 3.0 you should be warned that the kernel we will be getting is from the xorg-edgers ppa. This means that it could potentially be dangerous as there is a risk of installing the latest untested graphic card drivers that may not be fully compatible with your system yet. Installing a bad kernel and rebooting back into the old one is one thing but installing a bad graphic driver isn't as simple to recover from.
If you still want to go ahead and install the Kernel this is how.
Terminal
sudo add-apt-repository ppa:xorg-edgers/ppa sudo apt-get update sudo apt-get install linux-headers-3.0.0-8 linux-headers-3.0.0-8-generic linux-image-3.0.0-8-generic
If you don't want to install the latest graphic card drivers just in case they are not compatible with your system. You can remove the xorg-edgers ppa from the software sources. This will prevent the graphic drivers from being updated to the latest versions. Just remember to run the updater once you have removed it.
Now reboot and pick the new kernel in the grub menu.
If for any reason the kernel isn't working for you just reboot the system and choose the previously installed Kernel. Once you are back into your system running on the older Kernel just run this to remove Kernel 3.0 from your system.
Terminal
sudo apt-get purge linux-headers-3.0.0-8 linux-headers-3.0.0-8-generic linux-image-3.0.0-8-generic
