how to add new loadable module to kernel?
 

I want to add nvidia module to load at startup. I've loaded it with modprobe command and it worked, but after rebooting it wasn't there, so i have to do it again and again after each startup. I wander where Linux stores all the information about modules to load. I've checked /etc/modprobe.conf, but there was only sound modules.. :(
Red Hat have nice utility called ntsysv, but my current distro is Mandrake 10.1 (official). Can anyone help me? Thanks.

you just need to add an entry to modules.conf, try "alias char-major-195 nvidia"

It doesn't work. :( Maybe you know in which file Linux stores all the information about loaded modules.

we are currently in a situation where different distros are dealing with this issue in different ways

i think in mandrake 10.1
Edit the file /etc/modprobe.preload and add the word nvidia to it.

I had this problem back in 9.0. Since that time I have done an upgrade to 9.2 and later an upgrade to 10.0 Community. I have not subsequently done a clean install.

So, I don't know if 10.1 handles things the way 9.0 did.

To solve my problem in 9.0, I added the line "video_adapter" (without the quotes) to the file /etc/modules, and I added the line "probeall video_adapter nvidia" to the /etc/modules.conf file.

That fixed it, for me, back then. As I look now on my 10.0 system, my /etc/modules file still has the video_adapter line and my /etc/modules.conf still has the probeall video_adapter nvidia line.

So give it a try.

it worked!
 

Finally it worked, ndidia module is loaded at the startup. And according to the comment in /etc/modprobe.preload: "this file is for module-init-tools (kernel 2.5 and above) ONLY for old kernel use /etc/modules". Next time i'll study all comments in configuration files more carefully. :) But i'm still curious where the other modules are stored, cause my etc/modprobe.preload have got only 2 modules (including nvidia).
Thanks for help guys!

Interesting.

My modprobe.preload file does not contain the nvidia information, but my modprobe.conf file does.

I think if you rewrite the nvidia information from /etc/modprobe.conf to /etc/modprobe.preload nothing will change.
