Comment 8 for bug 384639

I was able to get the new kernel working after installing newer nvidia drivers. Here's the steps I took to get mine working. You should change the steps below to suit your architecture. If you have a 32 bit system, then you should download the 32 bit packages. Note: I don't really use the wget command (I downloaded the packages through Firefox) so if I used them incorrectly in this tutorial feel free to fix the directions to how you like. I just typed it here for your convenience.

1st) Use apt-get to purge the new kernel. If you don't need to do this you can skip this step. I just wanted to start fresh before installing the nvidia drivers and reinstalling the new kernel. As far as I know you have to install the drivers before the new kernel. I could be wrong about that but I just wanted to make sure before reinstalling the new kernel. Better safe then sorry.

sudo apt-get purge linux-headers-2.6.30-020630 linux-headers-2.6.30-020630-generic linux-image-2.6.30-020630-generic

2nd) Download and install the new nvidia drivers from "http://archive.ubuntu.com/ubuntu/pool/restricted/n/nvidia-graphics-drivers-180/".

wget http://archive.ubuntu.com/ubuntu/pool/restricted/n/nvidia-graphics-drivers-180/nvidia-180-kernel-source_180.60-0ubuntu1_amd64.deb
wget http://archive.ubuntu.com/ubuntu/pool/restricted/n/nvidia-graphics-drivers-180/nvidia-180-libvdpau_180.60-0ubuntu1_amd64.deb
wget http://archive.ubuntu.com/ubuntu/pool/restricted/n/nvidia-graphics-drivers-180/nvidia-glx-180_180.60-0ubuntu1_amd64.deb

sudo dpkg -i nvidia*.deb

3rd) Reinstall the kernel 2.6.30 packages and reboot. If you haven't all ready you should download the pre-compiled packages from "http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.30/".

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.30/linux-headers-2.6.30-020630-generic_2.6.30-020630_amd64.deb
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.30/linux-headers-2.6.30-020630_2.6.30-020630_all.deb
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.30/linux-image-2.6.30-020630-generic_2.6.30-020630_amd64.deb

sudo dpkg -i linux*2.6.30*.deb
sudo reboot now

If all goes well, all systems should be a go.
