Configuring my installation.graphics card/mouse and starting a UI

[DebianDummy]

Hello,
I realise I have another thread open, however this doesn't cover what has happend so far and the thread title doesnt match the problem.

The story so far:

I have an AMD Athlon 64
and a GeForge 6800GT

Downloaded debain sarge (need to have debian)
couldnt get a UI to work
startx returns the "no screens" error
looked around on forums and realised i needed to get etch not sarge
changed my .sources file and replaced sarge and stable with testing
updated
downloaded and updated files to upgrade to etch
downloaded the correct drivers for my nVidia GeForce 6800GT

Ok so i looked at nVidias website and the next step according to them is to run the command

sh NVIDIA-Linux-x86-1.0-9746-pkg1.run

which runs an interface that should take you through a step by step process to get my graphics card driver working.

I run the instruction and got the following:

No precompiled interface was found to match your kernel; would you like the installer to attempt to download a kernal interface for your kernel from the nvidia ftp site ftp.nvidia.com

so i selected yes even though im not sure what that means
and then i get:

No matching precompiled kernel interface was found on the NVIDIA ftp site; this means that the instaler will need to compile a kernel interface for your kernel

only choice is ok so i choose it (again i didnt understant what that last message meant)

then:

The CC version check failed:

you appear to be compiling the NVIDIA kernel module with a different compiler than the one that was used to compile the running kernel. This may be fine, but there are cases where this can lead to instabillity. The compiler used to compile the kernel was gcc 3.3; the current compiler is gcc 4.1

If you know what you are doing and want to ignore the gcc version check, select "No" to continue the installation. Otherwise select "yes" to abort installation, set the CC environment variable to the name of the compiler used to compile your kernel, and restart installation. Abort now?

what the hell! might aswell carry on so i select No

followed by:

ERROR: Unable to find the kernel source tree fo rthe currently running kernel. Please make sure you have installed the kernel source files for your kernel and that they are properly configured; on Red Hat Linux systems, for example, be sure you have the kernel source or kernel devel RPM installed. If you know the correct kernel source files are installed, you may specify the kernel source path with the '--kernel-source-path commad line option

sounds great!

I really have no idea what to do and seem to be feeling more and more thick, can anyone kindly suggest a solution for me as diving out of my window and splattering myself all over the floor seems to be a reasonable idea right now!

I also get an error about my mouse, how would i configure this correctly and is it neccessary to get as far as the GUI?

Thanks in advance.

the driver must be compiled against the linux kernel
source code; so try this:

1. "uname -r" to get kernel version: e.g., 2.6.17.3

2. then go download the kernel sources for 2.6.17.3 or
whatever, goto the directory where you have the source
code and read the README...

3. if you have a file /boot/config... copy it to yr
source directory as ".config" then do "make oldconfig"
...

hang in: it's not that hard.
