For Ubuntu 14.04, this is how your you can build xfsettings with the patches:

sudo apt-get install xfce4-dev-tools libexo-1-dev libgarcon-1-0-dev libxfce4ui-1-dev
git clone git://git.xfce.org/xfce/xfce4-settings
cd xfce4-settings
curl https://bugzilla.xfce.org/attachment.cgi?id=5681 > alexander-patch.diff
curl https://bugzilla.xfce.org/attachment.cgi?id=5723 > sean-patch.diff
Choose a patch to Apply: patch -p1 < <patch>
./autogen.sh && make && sudo make install
/usr/local/bin/xfsettings --replace

If you wanna to try other patch, first remove what's applied:
patch -R -p1 < <applied patch>

After playing, remember to remove the installed xfsettings:
sudo make uninstall

Title:
  Xfce resets TV mode to NULL when power cycled

Status in Mythbuntu, Ubuntu derivative focused upon MythTV:
  Confirmed
Status in xfce4-settings:
  Incomplete

Bug description:
  I had an HTPC with Mythbuntu 12.04 installed.  Upon upgrading a new
  behavior that if the TV is power cycled it no longer detects a link
  with the HTPC.

  When this happens I can find in the xorg log that there is an
  accompanying log item:

  [ 39829.509] (II) NVIDIA(0): Setting mode "NULL"

  After debugging with NVIDIA at
  https://devtalk.nvidia.com/default/topic/729955/linux/tv-stops-being-
  detected/ we've deteremined it's a X client that reacts to the RANDR
  events causing the mode to be set to NULL.

  Working through the list in an Xfce environment, the culprit is
  xfsettingsd.  If xfsettingsd is running, it causes the TV to come up
  in a NULL mode.  If it's killed, it remains in the mode it was
  previously running in.

  
  Until this is fixed, this behavior can be worked around with a simple shell script:
  ==============================
  #!/bin/sh
  #Fix TV state when HDMI link is lost.
  #By Mario Limonciello <superm1@xxxxxxxxxx>

  OUTPUT="HDMI-0"
  BAD_MODE="1280x720"
  GOOD_MODE="1920x1080"

  for MODE in $BAD_MODE $GOOD_MODE; do
   DISPLAY=:0 xrandr --output $OUTPUT --mode $MODE
   sleep 2
  done
