Ubuntu 8.10 Intrepid
So, after reading a post about NTSC tuner support in 2.6.26 I decided to upgrade my HTPC to Ubuntu 8.10 which is the development release of Ubuntu. So, after a seamingly smooth upgrade, I found out that Ubuntu 8.10 comes with 2.6.27 not 2.6.26… even better.
Nvidia drivers have previously required kernel headers, but not source. The new DKMS build system tells me that they now require source. I should have known better and not listened to it, but I spent I dunno how long trying to get a compiled kernel source tree to match my running system. After complaints about not being able to run under Xen, and misaligned struct_module and various other issues, I realised that I needed to apt-get install kernel-headers-2.6.27-2-generic, not kernel-headers-2.6.27-2. This is very important. Without the -generic bit, you don’t get a configured header tree, just a stock one. After realising this, I have had no problems with the development release. Everything works at lease as good as it did before, or better. The new X+nvidia drivers are WAY FASTER than on 8.04. My ATSC tuner is at least recognised now, but still isn’t really working.
