Bug#741695: xserver-xorg-video-intel: xv completely broken on HD 4400

[Dave K <bugs@soupy.org>]

I've been watching this bug as I've got similar hardware (System 76 Kudu
/ Intel(R) Core(TM) i7-4700MQ CPU @ 2.40GHz ) and similar symptopms.

I'm on Fedora 20, but I can work around the problem by explicitly
enabling SNA in xorg.  In my case adding the following works around the
issue:

Section "Device"
   Identifier  "Intel Graphics"
   Driver      "intel"
   Option "AccelMethod" "sna"
EndSection

Cheers!
