Hmmm... every time I try init 3 I get the Blank Screen of Death as well. So - easy peasy: from a shell-
<type your root password when it asks...>
(THis opens 'nano' - a very simple to use text editor. The inittab file you just opened is sort of like the autoexec.bat from windows.
Scroll down a few lines and you see a few lines of text lists numbers 1 to 6 and what each number does. Immediately after you'll see a line with a '5' in the middle. You can see that setting is described above. You need to change that 5 to a 3 and save it. Just use the command to quit and say 'yes' when it asks you to save before quitting)
Reboot and this will take you into the non-graphical Fedora.
When you're done installing, etc just remember to change your /etc/X11R6/xorg.conf like the guide says - just use nano again. It really is a lot better than vi for us newbies!
By the way - if you follow the guides and most information you would ordinarily be fine except that Fedora has that nice graphical loading screen (which is just annoying except the wife likes it). This really narks the system up after you install the drivers and change the xorg.conf file so have a look at this link before you try it:
Ignore all that stuff about patching the drivers and downgrading. The new ones work fine, though they try to download a kernel interface, then end up compiling thier own. Don't panic - it'll all be fine if you just carry on. Do NOT ignore the bit that goes:
# modprobe nvidia
# cp -a /dev/nvidia* /etc/udev/devices
# chown root.root /etc/udev/devices/nvidia*
Or you'll get locked up halfway through booting and end up reinstalling from scratch or going back to XP like I did...
When you install the driver and want to reboot (the bit above should be the last thing you do really before then) - open your inittab with nano again:
and change that '3' you put in back to a '5', reboot and if you followed the guides properly you'll be sorted, mate!
If not, come on back...
