+          With the removal of the xf86-video-* drivers, the TearFree option
+          is no longer functional. To work around this, upstream has added the
+          TearFree option to the default modesetting driver. This patch
+          backports this feature. Apply this patch if you are going to use Xorg
+          in an environment without a compositor (such as TWM, IceWM, Openbox,
+          Fluxbox, or Sawfish).
