Missing GLX extension
There would appear to be a bug, in nvidia-glx 6629 portage package.
If you get problems try the nvidia installer.

Did you do opengl-update nvidia?

Greetings:

I can confirm churchy's behavior:

glxinfo shows a working opengl subsystem with the nvidia drivers in the x86 branch.

(II) LoadModule: "glx"
(II) Loading /usr/X11R6/lib/modules/extensions/libglx.so
(II) Module glx: vendor="NVIDIA Corporation"
compiled for 4.0.2, module version = 1.0.6629
Module class: XFree86 Server Extension
ABI class: XFree86 Server Extension, version 0.1
(II) Loading extension GLX

glxinfo shows a broken opengl subsystem with the nvidia drivers in the ~x86 branch.

(II) LoadModule: "glx"
(WW) Warning, couldn't open module glx
(II) UnloadModule: "glx"
(EE) Failed to load module "glx" (module does not exist, 0)

opengl-update showed:

opengl-update --get-implementation
nvidia

in both cases.

There are some bugs in bugzilla (79796 and 76990) which seem to indicate that if you're using ~x86 for the nvidia drivers you need to be using ~x86 for xorg-x11 too. I haven't tested that by switching to ~x86 for xorg-x11, though, so that's just conjecture on my part. I can say the with both at x86 it seems to work for me.

I'm using an all ~x86 system and have trouble with glx, so having a ~x86 xorg won't help it seems. I do however have a suspicion that the nvidia-glx upgrade broke my xorg, so I'm remerging it now...

I'll let you know how it went...

These problems are possibly being caused by a bug in opengl-update (see here). Try running emerge sync and then emerge opengl-update, I think it's fixed in the latest version.

The new opengl-update solves the glext.h problem

To work aorund the problem just add:

=media-video/nvidia-glx-1.0.6629-r1 ~x86
instead of:
media-video/nvidia-glx ~x86
and remove opengl-update from package.keywords.

This will downgrade the nvidia-glx to the previous version (which works with the old opengl-update.
If you don't want to downgrade you have to add xorg, freetype to the package.keywords - But this blocked firebitd for me, since it didn't want to work with the new freetype. And adding firebird to the keywords didn't resolve the problem for me - so I decided to downgrade the glx.

I can confirm this problem, and I can further add that opengl-update is the culprit (after an hour of trying everything I could possibly think of).

And the stable x86 version also works with the unstable nvidia-glx-1.0.6629-r5.

Don't know if this helps but I noticed that GLX craps out after an emerge...

It almost seems as if env-update (or some similar clean-up utility) was switching back to Xorg GL. My workaround is basically to run opengl-update after an emerge.

This naturally only a broken link to NVidia GLX libraries problem. At least that is my case.
