I've been using Linux and Unix professionally since 1995, mostly in Linux-related sysadmin/systems architect jobs supporting academia. I generally know my stuff, but am very happy to learn something new and to be corrected when I'm wrong. Currently, I am the Fedora Project Leader.

@jonderry. Ohhhhh. Now I feel a little bit bad that I didn't put a bigger disclaimer on that. Because messing up your system a lot is definitely a possibility. How much stuff did it update? You said you can boot to single-user mode -- can you boot to runlevel 3? (Put "3" on the boot command line instead of "1" or "single".) I think maybe this should be a new question at this point.... ("Help! I followed mattdm's advice and now my system is screwed up. How do I fix it?")

@jonderry -- so far what you described doesn't seem to have doe anything (other than adding a repo file) so I'm not sure what to undo....

@jonderry — that basically means it can't contact any of the mirrors defined in your repo file, which makes sense in single user mode (no network). You can bring up the network by hand (ifup eth0 will probably do it) and then proceed.

@jonderry — yum install fedora-release-rawhide and then you'll have it.

Hmm. What is $LANG set to by default? Does putting that in your bashrc make it change?

comment How can I use my server to compile a kernel for my laptop?
— since they do have differences, you can optimize code differently and get different performance on each (some of which the kernel does at runtime, actually). But they're the same instruction set and generally work the same way at a high level.

@jonderry — that said, I've been running with the Fedora continuously-rolling development tree as my main desktop for several years now, and it's only occasionally caused me horrible pain. The alpha release is much safer than that. :)

@jonderry — cool, glad that worked. Another option would be to back-port the specific things you need (X and the kernel) to Fedora 14, either by building them yourself or by attempting to use the updated packages on F14. In fact, you might be able to get this to work on your F14 system by saying yum --enablerepo=rawhide upgrade kernel xorg-x11-drv-ati xorg-x11-drv-ati-firmware. But there's a lot of changes between F14 and F15 so it might try to pull in pretty much everything in order to do that. Dunno. :)

— that's the same x86_64 architecture as far as the kernel is concerned.

Is your laptop actually a different architecture?

@jonderry, with modern kernels and X, graphics cards are initialized by the kernel. See unix.stackexchange.com/questions/7943 and kernelnewbies.org/…, and the link to h-online in my answer above. Support for your card's family was just now added.
