+From a50b2b3412dd8e7f3916acb142c942e85ffcb3e5 Mon Sep 17 00:00:00 2001

+Subject: [PATCH 2/2] xf86-video-sis: remove the GlxSetVisualConfigs stub and
+ friends
+
+The function was an empty since 2008 at least. Remove it alongside the
+unused GLX visuals code.
+
+With this all the GL/GLX dependencies in the driver are gone.
