RE_ [olug] Second Monitor (I'm writing a book ) :)

[G.M.]

I'm trying to resolve my blank screen problem when I log out of X  to a 
console.Thinking it might be a driver issue I went to the nvidia driver 
archive to download an old driver 
....ftp://download.nvidia.com/XFree86_40...I downloaded 
NVIDIA_kernel-1.0-4191.mdk90up.i586.rpm and the GLX rpm 
NVIDIA_GLX-1.0-4191.i386.rpm but there's so many drivers listed I don't 
know if I got the right one for my kernel which is 2.4.21-0.13mdk and 
I'm running mandrake 9.1.When I first tried to install the NVIDIA_kernel 
rpm it said it couldn't find module nvidia.o.A quick locate found it at 
/lib/modules/2.4.21-0.13mdk/kernel/drivers/video/nvidia.o but a check of 
lsmod said it wasn't loaded so I did a modprobe nvidia.o and it said it 
couldn't find the module.So I cd'ed into the dir that nvidia.o was in 
and ran insmod ./nvidia.o and it installed it but I got this error > 
See http://www.tux.org/lkml/#export-tainted for information about 
tainted modu
les
Module nvidia loaded, with warnings

So I installed the NVIDIA_kernel rpm anyway and got this error>

nvidia.o installed successfully

Then I installed the GLX rpm and got this error>

Needless to say X wouldn't start.Can anyone tell me what these error 
messages mean?I assume for one thing it must be the wrong NVIDIA_kernel rpm.
