I want to try some of the new features in the btrfs filesystem, and to do that I need to use a newer kernel than is included in Ubuntu 12.04. To do that, I have installed linux-headers-3.4.0-030400_3.4.0-030400.201205210521_all.deb, linux-headers-3.4.0-030400-generic_3.4.0-030400.201205210521_amd64.deb, and linux-image-3.4.0-030400-generic_3.4.0-030400.201205210521_amd64.deb from the mainline kernel download here.
However, on rebooting into the 3.4 kernel, my desktop is stuck at a very low resolution and I cannot increase it to the full. This did happen when I first installed, but a simple install of the nvidia-current package got everything working nicely with my GTX570 card. There were appear to be some DKMS errors when I installed the kernel, and they indicated I should look at /var/lib/dkms/nvidia-current/295.40/build/make.log:
