Bugzilla Bug 215645

Building nvidia-drivers-169.09-r1 against sys-libs/glibc-2.3.6-r5 succeeds, but
produces a non-functional GLX module.  Attempting to startx causes the xorg X
server to shut down as soon as it tries to initialize it's GLX module. 
Commenting out the "load glx" line in /etc/x11/xorg.conf allows the X server to
startup, albeit without GLX support.

Changing to sys-libs/glibc-2.6.1 and re-emerging nvidia-drivers-169.09-r1
solves the problem, allowing X to startup with the GLX module loaded.

It would appear that there is an unspecified dependency in
nvidia-drivers-169.09-r1 on a version of glibc that is greater than 2.3.6-r5.

Systems that have a CHOST set to i386-xxx cannot use a glibc any greater than
2.3.6, so this is a real concern for those systems.

Reproducible: Always

What's the error when X dies? Can you attach your Xorg.log? Include emerge
--info?

The Xorg.0.log file from the failure has been overwritten.
I would have to downgrade my system from glibc-2.6.1-r0 back to glibc-2.3.6-r5
in order to get it to fail again, and I'm not about to do that as it breaks
a lot of other things.

The Xorg.0.log file was an absolutely normal startup sequence, with the 
nvidia's gpu and the Dell flatpanel monitor being correctly detected, 
identical right up to the line

(II) Initializing extension GLX

this was then followed by a

Backtrace:

with NO additional information or errors!


I've created an attachment with the current successful Xorg.0.log.
It is identical to the failure case up to the line
"(II) Initializing extension GLX" which I have marked.


My current emerge --info is:

Xorg.0.log

Failure point marked with <<<===

Chainsaw is taking over this package.

This is very interesting. Looking at
http://us.download.nvidia.com/XFree86/Linux-x86_64/169.09/README/chapter-02.html
NVIDIA claims that any version of glib above 2 will work. I wonder if GLX needs
features in a certain glibc. Could you try to start X with GLX but without the
nvidia driver (perhaps using nv)?

Before spending any further time on troubleshooting, please try the following
new driver releases in the order listed:
173.14.05
173.14.09
177.13 (masked)

Should this fail to alleviate the issue, please reopen the bug and answer the
questions asked in comment #5.
