Description Jie Luo 2008-04-22 22:02:03 UTC 
Today when I'm try to run glxinfo with AIGLX disabled, I find it does not work. It gives me a error.

Error: couldn't find RGB GLX visual

I find this piece of code in glxcmds.c in mesa, and (*ppsc)->configs == NULL is true. 

    /* Check to see if the GL is supported on this screen */
    *ppsc = &((*ppriv)->screenConfigs[scrn]);
    if ( (*ppsc)->configs == NULL ) {
        /* No support for GL on this screen regardless of visual */
        return GLX_BAD_VISUAL;
    }

So there must be some problem with the initialization of __GLXdisplayPrivate. I will take a further look, if I have time.

I'm surprise that no one have noticed this part was broken.

I think this is a regression caused by one of the GLX visual reworks.

Is this still an issue with xserver 1.6.x?

This issue is fixed with xsrver 1.6.3.901. I didn't check other versions. But I believe it is fixed with 1.6.x.
