GLX causes X server crash on Geforce6600+6.1-RELEASE-p3+xorg6.9.0+nv1.0.9746

[nickhilliard]

It seems that the combination above causes GLX to break horribly on my box. GLX is not initialised properly by X, and a warning appears in /var/log/Xorg.0.log:


(II) Loading sub module "GLcore"
(II) LoadModule: "GLcore"
(II) Loading /usr/X11R6/lib/modules/extensions/libGLcore.so

The X server starts normally, but if I execute any GLX application (e.g. glxgears), the screen goes into text mode, the X process starts chewing up 100% CPU and the keyboard becomes non-responsive. The only way to recover control of the machine is to log in remotely and issue SIGKILL to the X server process.

configuration:

freebsd 6.1-RELEASE-p3
xorg - 6.9.0
nvidia driver 1.0.9746
club3D Geforce 6600/256 (not GT)

This is on a clean re-compile of all relevant ports from scratch on an effectively clean box (i.e. all ports nuked beforehand). If I downgrade to the 1.0-8776 driver, it all works fine.

xorg.conf + log file attached.

suggestions? How can I get extra debug information which could be used for diagnosis?

According to your log file, you're loading the glx extension that comes with Xorg, not the one from the nvidia driver.

Did you install the driver from the ports tree?

yes, i installed the nv1.0.9746 driver from ports.

Well, I suggest moving the Xorg libglx out of the way, and linking the nVidia glx (wherever the port installed it to) to the proper location.

if I shut down X, unload the 1.0.9746 nvidia.ko kernel module, then load the 1.0-8776 module and restart X, everything works fine. this would suggest it's not a library problem.

I don't care what it suggests :-) Unless your Xorg log file is lying, you're still loading the Xorg GLX library, which is a big no-no.

Hi,

don't know if releated, but the latest release 9746 freezes definitely my freebsd box (6.2).
Had to go back to the 9631.

PS : I have the same problem with my linux (etch) boxes, and same fix :-(

I agree with adamk75, Xorg is loading the wrong glx module.

I had it happen once too, I solved it by pkg_delete nvidia-driver-1.0.9746_1 , rm -rf /var/db/ports/nvidia-driver/ (this removes previously set build options). Also have a look in /usr/X11R6/lib/modules/, drivers and extensions, remove any leftover XXX-* files.

Then rebuild & reinstall the nvidia-driver, cd /usr/ports/x11/nvidia-driver/ && make all install clean.


replace with your installed version, have a look in /var/db/pkg/ to see which one is installed.

It turned out that this was the problem after all. Thanks for the suggestion.
