NVIDIA driver and NVIDIA kernel mismatch, NVIDIA driver and kernal diffrnt version

[meangreen85]

Hi All,

I am not too sure what kind of information you need, I tried to look around for posting instructions but didn't see any. I will try and just give you all information.

SL version 6.1
graphics card is GeForce GTX 460

I am getting the following message when I run the program MATLAB.

[powder@CaseyWayne PolyAmidNylonCylinders_380umD]$ matlab
Error: API mismatch: the NVIDIA kernel module has version 290.10,
but this NVIDIA driver component has version 295.20. Please make
sure that the kernel module and all NVIDIA driver components
have the same version.


I tried to install NVIDEA driver a while back and then followed some instructions to use elrepo. I didn't start getting this message until I updated Scientific linux from 6.0 to 6.1. From my research it seems like it is an issue of having to reinstall the driver and kernel from the same source, but I have NO idea how to do that. I don't think I was even able to properly install the NVIDEA driver from the website before I found the elrepo instructions.

How do I get the NVIDEA driver and NVIDEA kernel to match? I am a noob, so I will require specific steps.

THANK YOU SO MUCH!
Casey

It is my understanding that if you install Nvidia driver using Kmod, that future rebuilds are unnecessary....maybe someone else can chime in here. I getting ready now to do a clean install of 6.2 on my precision with a Quadro fx3800 so I'll report back if anything comes to mind.

I am not a graphics person and curious if you need the package dkms for that to work automatically?

No kmod is an alternative to dkms, kmod is basically a mechanism to build one binary kernel module that works over a range of kernel updates rather than just for one specific kernel binary (I don't know the exact details as I have so far chosen dkms for myself as I understand how dkms works and consider it perfectly reliable, so don't see the need for kmod for myself).

Aahh, ok
Thanks for the info Tux99

Ok, so how do I do this kmod install? Do I need to uninstall something? If I need to unstall the NVIDIA driver, how do I do that so that I don't mess up the NVIDIA kernel? Will the computer automatically update the driver for me?

Thanks,
Casey

Just follow the drill here....you won't need to rebuild the nvidia driver in the event of a kernel update. HERE

This will take care of the nouveau driver for you.
