Comment 65 for bug 384001

If I ssh to a remote box, and I try to run 'glxinfo' on the remote system, it fails unless I explicitly force indirect mode via LIBGL_ALWAYS_INDIRECT.

The problem is that without LIBGL_ALWAYS_INDIRECT set, glx_direct gets set to true in glxext.c:

---
glx_direct = (getenv("LIBGL_ALWAYS_INDIRECT") == NULL);
glx_accel = (getenv("LIBGL_ALWAYS_SOFTWARE") == NULL);

   /*
    ** Initialize the direct rendering per display data and functions.
    ** Note: This _must_ be done before calling any other DRI routines
    ** (e.g., those called in AllocAndFetchScreenConfigs).
    */
   if (glx_direct && glx_accel) {
      dpyPriv->dri2Display = dri2CreateDisplay(dpy);
      dpyPriv->driDisplay = driCreateDisplay(dpy);
   }
   if (glx_direct)
      dpyPriv->driswDisplay = driswCreateDisplay(dpy);
---

Then in AllocAndFetchScreenConfigs(), we get our visuals and fbconfigs via:
      getVisualConfigs(dpy, priv, i);
      getFBConfigs(dpy, priv, i);

but then they get thrashed by:
      if (psc->driScreen == NULL && priv->driswDisplay)
         psc->driScreen = (*priv->driswDisplay->createScreen) (psc, i, priv);

which is driCreateScreen in drisw_glx.c and ends up doing:
   psc->configs = driConvertConfigs(psc->core, psc->configs, driver_configs);

which results in psc->configs being set to NULL which is causing GetGLXPrivScreenConfig to return GLX_BAD_VISUAL and thus causing glxinfo to bail.
