[SOLVED] Modprobe does not show modules for graphic card

I am posting this in Newbie Corner because I think I have missed something obvious so please don't be rude or unkind!

The kernel drivers for my graphic card (nvidia GT440) don't appear to load.

lspci -v shows none in use, and only lists nvidiafb as a kernel module.
modprobe doesn't find any of the 3 video drivers that were installed with pacman.
lsmod doesn't list any modules connected to video drivers
Xorg -configure tries all three but then can't finish as they are not loaded/active/available?
nvidia-xconfigure does run but then startx fails because the display/screen is not there as nothing is driving the display.

I am installing from scratch. (I have done this a few times and never hit this problem before.)
From the new installation CD i686 I selected everything and ran the install.
Then I ran pacman -Syu followed by -S xorg (excluding video drivers) xorg-init xorg-twm xterm xorg-utils (later  removed with -R) xorg-server xorg-server-utils & xf86-video-nv xf86-video-vesa xf86-video-nouveau. To get the nvidia-current to install I removed xorg-utils xorg-xdriinfo libgl & xf86-video-nouveau. This is all my system has in it apart from dbus which I reliased I had missed earlier. I'm trying to sort this out before installing KDE or xfce4, so there is no users set up yet, nor any window managers. Before using a xorg.config file startx would create a display with 3 white xterm windows, I think this means X is OK. This is my second attempt at this, I did install  the whole of KDE4 last time but still hit this issue so never got to a working desktop, just stuck at the end of the window manager loading and never passing over to KDE.

Re: [SOLVED] Modprobe does not show modules for graphic card

Wow, your post is confusing. So let's start from the beginning: What do you have installed currently and which driver do you want to use?

Re: [SOLVED] Modprobe does not show modules for graphic card

I would check/post your /var/log/Xorg.0.log.

I also recently reinstalled a few times (gtx460), I believe all that I have done is:
pacman -S xorg-server xorg-xinit xorg-utils xorg-server-utils
pacman -S nvidia nvidia-utils

Re: [SOLVED] Modprobe does not show modules for graphic card

Thanks for looking at this.
I have tried to use 4 different drivers, vesa, nv, nouveau (now removed with pacman -R), & nvidia. I would be happy with either of the last two but I think if I can get any one working the same fix will sort all of them because at the moment I can't get any to show as "in use" with lspci -v.

This is the first time I have used wgetpaste so the link for my xorg.log is http://paste.pocoo.org/show/471921/

The only error showing is :- (EE) Failed to initialize GLX extension (Compatible NVIDIA X driver not found)

Re: [SOLVED] Modprobe does not show modules for graphic card

Your log shows it's trying to use nv (ugh) and eventually settles for vesa. If you want to use nvidia, you need to remove both xf86-video-nouveau and xf86-video-nv (and remove xf86-video-vesa too; it doesn't hurt to have it, but it makes debugging a bit harder). Then install nvidia and nvidia-utils, like epikal says. And then a very simple thing... reboot. That should pretty much do it. If it doesn't, post the log again.

Re: [SOLVED] Modprobe does not show modules for graphic card

Did what Gusar sugested. new Xorg.log here http://paste.pocoo.org/show/472029 & pacman.log http://paste.pocoo.org/show/472031. Pacman log shows :- ERROR: Module nvidia does not exist in /proc/modules - In order to use the new nvidia module, exit Xserver and unload it manually. I rebooted as I don't know how else to exit Xserver or unload it. Still no joy though, can't see nvidia listed as a module anywhere.

Re: [SOLVED] Modprobe does not show modules for graphic card

The nvidia package should install the module. Is this package installed? If it is, what happens if you load the module manually - by doing

modprobe nvidia

as root? What does dmesg say after you've tried this?

Re: [SOLVED] Modprobe does not show modules for graphic card

When I run

modprobe nvidia

.
I get a Fatal Error - Module nvidia not found. Is there some program that tells the kernel to find the modules and then uses them? I may have missed installing something. The dmesg log shows nothing relating to nvidia before or after running this command.

Re: [SOLVED] Modprobe does not show modules for graphic card

Well, you clearly don't have the nvidia package installed. That one has the module. Or maybe, are you using a custom kernel?

Re: [SOLVED] Modprobe does not show modules for graphic card

I did a pacman nvidia & nvidia-utils install, twice. Also I tried with xf86-video-vesa xf86-video-nv  xf86-video-nouveau earlier. They all seemed to install OK but never showed up in lsmod or lspci -k or v.
Just to try to move this on I have installed the alsa-utils package but no snd_* modules are showing either so there are no sound cards found. I am nearly at the stage of a format and new install but I can't see that anything will change and this will be the 3rd install.

Re: [SOLVED] Modprobe does not show modules for graphic card

Thanks to everyone for looking at my problem. I came to the conclusion that the install media was corrupted and the system never loaded properly. I have now done a net install with none of these issues.

I will try to mark this topic closed, if I can work out how to do that.
