Do a modprobe nvidia as root then try to start the X server again.

What does this mean?

Sorry for double posting, but please, anyone. What does that mean?

You did modprobe nvidia? You loaded your nvidia module. If "nvidia" is in your xorg.conf, then you won't have to do this at every startup. It should work for you fine. And don't forget glx.

su - : is a command to run a shell with root permission.

modprobe is a command to load a module.
modprobe nvidia will load nvidia module

# is a way to put comments in bash (bash is the default linux shell)
everything after # in a line will be ignored.
You probably have seen this in a configuration file.
when you want to delete something in a config file it's better to just put a # in the beginning of the line.
In this way you can remember the change you made. then you can delete the # in order to undo the change.

Unix/linux systems have a really strong manual pages system.
when u don't know what a command does try using the manual:

man modprobe
man su

I tried it again. Got the same damn error again.

This may have already been mentioned before, so apologies if it's a repeat. Once you run a modprobe command, it will attempt to load the kernel module, as perfect_circle has described (nicely done BTW). The next thing to do would be to verify that it has successfully been loaded by running the lsmod command (which just lists the various kernel modules that have been loaded. If nvidia appears in the list, you have successfully loaded it, if it is absent, the load failed. Example

I got it solved by going to #nvidia on freenode, started spamming until someone finally responded (usually an idle channel). He told me to delete two files from the kernel's driver directory, nvidia-agp and something I don't remember. lol
Anyway, I got it fixed after deleting them. Thanks for trying to help me. Appreciated.

Is there a differance between the two. When I installed 10.1 and was having problems with getting the nvidia drivers to operate correctly it states in the readme to modify the XF86config file and in here I see mention of the Xorg.conf. I went back to 10.0 for the time being but I do remember both files being in my /etc/X11 folder? Does it matter which one is modified? My nvidia drivers would install okay but I could never get X going. Even after modifying my X86Config file.

mykyl,

mandy 10.1 uses xorg instead of xfree86; however, the xorg.conf file that you see is actually just a symbolic link to XF86Config... so just modify that file as per nVidia's instructions.
