Comment 13 for bug 454220

Note related bug in jockey: https://bugs.launchpad.net/ubuntu/karmic/+source/jockey/+bug/451305

I installed linux-headers-generic-pae and did a

dpkg-reconfigure nvidia-185-kernel-source

But I got the "Module build for the currently running kernel was skipped since the kernel source for this kernel does not seem to be installed" error (even though the headers were there). I had to

apt-get remove --purge linux-headers-2.6.31-15

And then, when I did an

apt-get install linux-headers-2.6.31-15-pae

it automatically rebuilt (successfully) the nvidia.ko.

(Also, I note that when xorg fails, it restarts very very quickly and doesn't ever seem to give up, making it impossible to login to a VT, as was possible with the earlier init scheme. This should probably also be considered a significant bug.)
