For those trying the above commands...  the curl to get the patch files is likely not working.
I'm not motivated enough on curl to figure out the problem, but i was able to copy/paste with a browser.
If you are unsure, look at the patch files, git diff, the output of patch, etc...


For me the latest git did not fix the problem.
Sean's (updated) patch also did not fix the problem.
Alexander's patch *did* fix my problem.

My use case is with a single display attached to a A/V receiver.  Turning the receiver off, and back on did not come pack.  
Using alexander's one liner, it works great.

IMHO, this is a big issue, and i'm shocked that it's not been rectified
yet.

Title:
  Xfce resets TV mode to NULL when power cycled

  Confirmed

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
  ==============================
