Can't load nvidia module

shruggy1987 · Posted: Thu Feb 10, 2005 11:57 pm Post subject: Can't load nvidia module

I emerged nvidia-glx so that I can get my nvidia GoForceFX card up
and running. After the emerge, I try to load the module:
modprobe nvidia
and i get an error output:
FATAL: error inserting nvidia (/lib/modules/2.6.10-gentoo-r6/video/nvidia.ko): Invalid module format.
Why is this and how should I fix it?

It's most likely due to your kernel being compiled with a different GCC version than your kernel modules. Try recompiling your kernel, then the module again, and everything should work.

At least, it worked for me

I've got the same problem
I tried to unmerge all nvidia related ebuild and my kernel (ck-source-2.6.10-ck5).
I reinstalled my kernel, reinstalled nvidia-glx and nvidia-kernel...but I still have this same problem

what particular nvidia ebuild are you using?

You may need to go to package.keywords and enter in nvidia-kernel ~x86 (dont forget the media-video or whatever dir it is)
I had a compile problem with nitro.. but this fixed (maybe with ck as well.. dont remember)

/usr/src/linux must point to the correct kernel sources i believe, make sure its up to date if you updated kernel, then reinstall nvidia-kernel

Yes my link /usr/src/linux does point to the correct kernel.
I have tried the ~x86 keyword for nvidia (glx and kernel) but without any improvement.
I heard also that the problem was with 2.6.10 kernel.
That is why I installed gentoo-dev-sources-2.6.9, and now nvidia module can be inserted in the kernel without any problem. (at least a modprobe nvidia do not return any error message)
But now I have very poor quality using "nvidia" in xorg instead of "nv" driver, and glx gears return

i am using a 2.6.10-morth24 sources and both nvidia 1.0.6629 and 6111 kernels work fine. Are you sure kernel module and glx are the same version? unmerge and clean both and remerge. did you do opengl-update nvidia ?

Actually the problem was in my xorg.conf (see https://forums.gentoo.org/viewtopic.php?p=2121152#2121152)
Now everything works just fine !!!!

Thanks for your help anyway !
