Segfault core dump over innocently missing GLX

[DebianCoder]

The recent and buggy 1.0.96xx nVidia driver only works with GLX disabled. See my report:
http://www.nvnews.net/vbulletin/showthr ... 332&page=8

Now while X.org works that way, without GLX, VLC and mplayer crash hunting for OpenGL viz plugin support. At least that is my impression.

I could remove OpenGL stuff from VLC by compiling it myself. But shouldn't there be a dynamic command line switch for that, too? Anyway, no reason to crash over missing OpenGL. Even if I needed that somehow for video, I should still be able to play audio files.

This is an extremely fresh Debian Etch++ system with GNOME just installed today, kernel 2.6.20.15 and 2.6.22.1 both producing the same result. VLC from Debian 'unstable' repos.

VLC version 0.8.6c Janus
Compiled by sam [snip]
Compiler: gcc version 4.1.3 20070429 (prerelease) (Debian 4.1.2-6)

Here is a stack trace.

to avoid the crash, just don't use opengl output in vlc

you can use X11 if XVideo doesn't work with a compositing manager

The crash happens at launch. I mean just opening the program without any file. This is VLC checking its plugins list, I think. Is there any option to tell VLC to ignore OpenGL or video in general? The only thing I found in the docs was to recompile with OpenGL disabled but that is a pain.

This is X11 by the way...

[funman]

you can delete the plugin, /usr/lib/vlc/video_output/libopengl_plugin.so

That did it. VLC works now. There were two libraries, one for glx and one for opengl. I moved them both out of VLC's folder into a holding area until nVidia fixes their driver and I can re-enable GLX.

So, thank you for prompt and kind help. I suggest error checking during plug-in loads.

Thank you!
