[gentoo-user] Strange Xorg behaviour, not (always) loading nvidia module

[gentoo-user] Strange Xorg behaviour, not (always) loading nvidia module

[Pupino]

Hi all,
I've got a weird trouble with Xorg...
At boot Xorg is loaded (it's in the default runlevel) but it does not
load the nvidia driver, but if I restart it from the command line
(without any change in the config) it works and loads the module
normally...
What could the trouble be? I have absolutly no clue...
Thanks in advance for any help

Yes! I've found this:
(EE) Failed to initialize GLX extension (Compatible NVIDIA X driver not found)
that is the only error reported...
But this suggests me nothing... I've looked at eselect and nvidia is
the opengl interface...
revdep-rebuild tells it's all ok...
I knew not other places to investigate...

All you have to do in order to get the proprietery nvidia drv working
is:

1) make sure the open src nvidia drv is not built in-kernel or as kernel
module:

========
   Location:
     -> Device Drivers
       -> Graphics support
         -> Support for frame buffer devices (FB [=n])
	     -> nVidia Framebuffer Support = [N]
========

2) emerge nvidia-drivers
3) make sure /etc/X11/xorg.conf has >Driver "nvidia"<, not "nv" in
section "Device"
4) eselect opengl set nvidia

Thanks for the help Daniel, but what you say hasn't fixed my problem...
I had framebuffer support in the kernel config, but not the nvidia fb
support, I've tried to remove it at all, but still doesn't work... the
other steps you have listed have already been done. In fact if I type
/etc/init.d/xdm restart after boot the driver is loaded correctly and
all works...

No, AFAIK, only the open source "nv" frame buffer (FB) driver can't work
together with the driver from Nvidia. You can have another (e.g. VESA)
FB support along with the proprietary driver.

Have you re-emerged "nvidia-drivers" after you recompiled the kernel?
If you use binary storage for the compiled packages, remove the
nvidia-drivers from there before emerging. I had such a problem:
portage extracts the backup package without really rebuilding the
driver (perhaps because it sees the same versions and USE flags).

So, you could try:

rm $PORTDIR/packages/All/nvidia*
emerge nvidia-drivers
eselect opengl nvidia

Yes, i've got the vesa fb driver and not the nv one...
fot the binary storage, I don't use that and however I've tried to
recompile both xorg-server and nvidia-drivers... but without result...
Thanks the same however!

The init sequence here is saying something like:

"udev is loading module nvidia...[OK]".

It is in the very beginning and if remove xdm from the init the
nvidia module is still loaded although unused. So, you could try to
remove xdm from your init, reboot and check if nvidia is loaded. If it
is absent from the output of "lsmod" you could try to make it load
autamatically by:

"echo nvidia >> /etc/modules.autoload.d/kernel-2.6"

...or even better - check if there isn't something wrong with udev.

Other than this, I'm running out of ideas.

udev loads correctly the nvidia module with and without xdm in the
default runlevel
I don't know what to think about this...
