I'd probably look at pre-built versions of the Kernel before jumping into compiling your own. The Mainline Kernel PPA should be your first port of call. Pick a version, install the package and reboot. If it works: awesome. If everything explodes, just select an older version from Grub and remove the package once you're booted up.

If you do want to follow the dark path of compiling your own kernel, I've written a few answers over the years that might help point you in the right direction.

• Building own kernel on ubuntu


• Error when I try to compile the kernel 2.6.37


• Correct way to apply patches to your kernel?


• 2.6.37 (or 2.6.36) Ubuntu Kernel in Maverick. Is this possible and where can I get it?

They're old posts but everything in them should still apply today.
