when i install nvidia driver using :
sh Nvidia--Linux-x86-185.51-pkg1.run;
Kernel module compilation complete;
but then i got an error:
Unable to load module 'nvidia.ko'. This happens most frequently when this kernel module was built against the wrong or improperly configured kernel sources, with a version of gcc that differs from the one used to build the target kernel, or if a driver such as rivafb/nvidiafb is present and prevents the NVIDIA kernel module from obtaining ownership of the NVIDIA device(s)

this is the part log which is useful i think:


Kernel module compilation complete.
ERROR: Unable to load the kernel module 'nvidia.ko'. This happens most
frequently when this kernel module was built against the wrong or
improperly configured kernel sources, with a version of gcc that differs

help me deal with it .

Welcome to LQ!

Please tell us what you did up to that point.

I got the same error message last week. After a fresh install of
Slackware64 -current, I changed kernels and did some other stuff
to configure my system before rebooting. Since I setup my NFS
shares, I thought I'd go ahead and install the Nvidia driver.
Can't do that until the system is rebooted and running the
kernel within Slackware, rather than from the CD/DVD.

Since you didn't give us much to go on, I'm guessing.

Looking at that log, I think that you are running the non-SMP version of a Slackware kernel.
However, installation of the kernel-source package results in kernel sources below /usr/src that are pre-configured to build modules for a SMP kernel. This means that the modules you have built (such as the nvidia module) will refuse to load in your running kernel. The error you will get is
Check out this readme for Slackware 12.2: ftp://slackware.osuosl.org/pub/slack...sdk/README.TXT which explains how you can re-configure your kernel sources. You will have to follow these instructions, and then try to install that NVIDIA driver again. This time, the module that is compiled should properly work with your non-SMP kernel.

Thanks .The fist kernek i used is non smp kernel;but i dont know how to make the smp kernel.
Then i see a article(http://www.linuxforums.org/forum/sla...re-11-0-a.html) ,i know that:
Slackware kernel built with "framebuffer" support leads to my problem ,so i rebuild the kernel without "framebuffer",after i use the new kernel ,i can install the nvidia kernel;

What's more, my new kernel is SMP kernel :I dont know what happened:i did not buid the smp kernel ,i just buid the kernel without framebuffer ;
so can you tell me the reason?

Today i find a new solution to my problem:i just need to make an initrd.I got the idea from the ReadMe.initrd file in /boot.
