The problem with giving you a better error message is that it's not giving me a better error message. It gets to the point where it tries to load the login screen and crashes directly to the oops screen without flashing an error message or anything else.
The reason I wanted to try to do a yum update was that I was trying to see if it was drivers or some other obscure setting that was causing the crash. I googled my hardware and all the forums said do a yum update if you're crashing from the start, so that's what I tried first. Then of course that didn't work either, so I tried finding out what would cause yum to crash and was told to edit my .repo files. Which would be wonderful if somebody also told me how to access them.
As for the install, I did the basic GUI install the whole way, I got no error messages or crashes during installation, and I actually reinstalled to make sure that was the case. Unless I'm missing something subtle I don't think there's a problem with my install. I installed from a DVD if that makes a difference.
Ok ifconfig gives me this:
lo Link encap: Local Loopback
inet addr: 127.0.0.1 Mask 255.0.0
inet6 addr: ::1/128 Scope: Host
UP LOOPBACK RUNNING MTU: 16436 Metric: 1
and all the rest report as 0, which I think probably means I'm not actually connected to anything.
