Installing a 3.0 kernel on Ubuntu 11.04 (natty)

Ok, I saw the warning but didn’t think it applied to me. Don’t assume it doesn’t apply to you!

Remove any proprietary ATI/AMD drivers from your Natty installation. You can put them back on after we install the new kernel.

Now that you’ve checked for anf removed any ATI proprietary drivers, visit this URL and pick out the kernel that you want to try.

In my case, I was running the latest natty kernel on a new (but low-end) Toshiba C650D laptop. It was crashing constantly, never running for more than an hour. As there weren’t any clear indicators in the logs, and the hardware worked fine on Windows, I wanted to try a different kernel. I wanted to the newest kernel possible in the hopes that whatever issue had been resolved.

I opened the above Url and scrolled way down to the bottom of the page. All the way to “v3.0.4-oneiric”. It was dated four days ago – that ought to be new enough! As I’m running 64 bit 11.04, I need the “amd64” binaries. Download the appropriate ones, “headers…all” and the “headers” and “image” file for my architecture.

[code] linux-headers-3.0.4-030004_3.0.4-030004.201108301138_all.deb linux-headers-3.0.4-030004-generic_3.0.4-030004.201108301138_amd64.deb linux-image-3.0.4-030004-generic_3.0.4-030004.201108301138_amd64.deb [/code]

Next, open a terminal window and cd to the folder where your binaries are located. Run the following command to install the new kernel: [code] /sudo dpkg -i /linux-headers-3.0.4-030004_3.0.4-030004.201108301138_all.deb linux-headers-3.0.4-030004-generic_3.0.4-030004.201108301138_amd64.deb linux-image-3.0.4-030004-generic_3.0.4-030004.201108301138_amd64.deb [/code]

Let it run for a minute or two and if there are no errors reboot. If you have errors, fix them, try the install command again and reboot. If Grub doesn’t prompt you to choose a kernel, check it from terminal once you’re logged in. with the following: [code] /uname -r /[/code]

There you have it! Running a 3.0 kernel on Ubuntu 11.04, Natty.
