Description Derek Freeman-Jones 2007-06-21 18:29:39 UTC
Just downloaded the latest version of compiz from the fusion git clone and found the request to get the client extensions does not return the last extension - most importantly the GLX_EXT_texture_from_pixmap extension.

If I run glxinfo - GLX_EXT_texture_from_pixmap is in both the server and client list.

I made a quick fix to check if GLX_EXT_texture_from_pixmap is the server extensions which works, but I don't think thats the right thing to do as this problem has only a appeared recently. Probably when I upgraded to 7.2.

Quick fix: 

    glxExtensions = glXQueryExtensionsString (dpy, screenNum);
    if (!strstr (glxExtensions, "GLX_EXT_texture_from_pixmap"))
+       glxExtensions = glXQueryServerString ( dpy, screenNum, GLX_EXTENSIONS );
+       if ( !strstr ( glxExtensions, "GLX_EXT_texture_from_pixmap"))
+       {
        compLogMessage (display, "core", CompLogLevelFatal,
                        "GLX_EXT_texture_from_pixmap is missing");
        XFree (visinfo);

        return FALSE;
+       }

without ths patch compiz fails to start and hard locks my machine - but thats probably due to my conifg?
