Description Marcin 2010-03-30 09:12:22 UTC
Xorg segmentation fault with xorg-1.7.6. When typing startx, onscreen log says:

could not find "dri" and "dri2" module, and outputs backtrace. Tried with diffrient kernel versions (2.6.30,, but no success.

Comment 3 Marcin 2010-03-30 09:59:14 UTC
Log says that build operating system differs from the current one, but after recompiling kernel, i've recompiled xorg-server and nvidia-drivers, so this could not be a problem. 
Comment 4 Alan Coopersmith 2010-03-30 10:03:04 UTC
According to the log, you're not using DRI, nor Mesa, but Nvidia's
libglx, and the segfault is in their code, so you'll have to report
this to them:

(II) Loading /usr/lib64/xorg/modules/extensions/libglx.so
(II) Module glx: vendor="NVIDIA Corporation"

9: /usr/lib64/xorg/modules/extensions/libglx.so (0x7fbd1ee19000+0x288bff) [0x7fbd1f0a1bff]
Segmentation fault at address (nil)

Could you please put a breakpoint on LogVWrite and step through to see what it's trying to print when it crashes?
Comment 6 Marcin 2010-03-30 13:29:20 UTC
I think it's solved. Installation nvidia-driver from nvidia.com rather than from gentoo portage works well, so the problem is in gentoo driver ebuild. Thanks anyway.
