X craches when loading GLX

awn · 07-12-11, 10:26 AM

Hi

I am trying to get Nvidia drivers with GLX up and running but I am having quite some troubles...

I could really use some hints on how on how to debug this, here is what I got when running X in gdb.

------- SNIPPET -----------
(II) LoadModule: "glx"
(II) Loading /usr/lib/xorg/modules/extensions/libglx.so
(II) Module glx: vendor="NVIDIA Corporation"
compiled for 4.0.2, module version = 1.0.0
Module class: X.Org Server Extension
(II) NVIDIA GLX Module 275.09.07 Wed Jun 8 14:34:43 PDT 2011
------- SNIPPET -----------
(II) NVIDIA(0): [DRI2] Setup complete
(II) NVIDIA(0): Screen initialization complete
(==) RandR enabled
(II) Initializing built-in extension Generic Event Extension
(II) Initializing built-in extension SHAPE
(II) Initializing built-in extension MIT-SHM
(II) Initializing built-in extension XInputExtension
(II) Initializing built-in extension XTEST
(II) Initializing built-in extension BIG-REQUESTS
(II) Initializing built-in extension SYNC
(II) Initializing built-in extension XKEYBOARD
(II) Initializing built-in extension XC-MISC
(II) Initializing built-in extension XINERAMA
(II) Initializing built-in extension XFIXES
(II) Initializing built-in extension RENDER
(II) Initializing built-in extension RANDR
(II) Initializing built-in extension DAMAGE
(II) Initializing extension GLX

Program received signal SIGSEGV, Segmentation fault.
0x00007f26f7570f72 in backtrace () from /lib/libc.so.6
(gdb) bt

#8 0x000000000046e6fa in InitExtensions ()
#9 0x0000000000421f99 in _start ()
(gdb)

At this point I have a nvidia logo on my screen.

If I disable GLX everything works.

I'm seeing the exact same thing, I'm running Ubuntu Natty on a Zotac ID40 (Nvidia ION 2 GTX 218). The only way to get X started is to disable GLX, I wasn't able to get anything meaningful from strace/gdb, and I get a segfault registered in dmesg whose location changes every time I start X.
