- Added n_xserver-optimus-autoconfig-hack.patch for FATE#316410. This

Browse Source 
is a little hack to make the X server autoconfigure the output sinks
  for Optimus laptops.  This lets them automatically use outputs that
  are only wired to a certain GPU. To be removed once our desktop
  tools can configure this easily.

Subject: [PATCH] autobind GPUs to the screen, (v3)
this is racy and really not what we want for hotplug going forward,
but until DE support is in GNOME its probably for the best.
v2: fix if config or slave config is NULL
v3: fix multi useful slaves
DO NOT UPSTREAM.
