Re: [Bug 1308105] Re: Xfce resets TV mode to NULL when power cycled

 

Hi Greg,

    Trying to follow your instructions.

     What do you mean by... and synaptic to lock this version....

     What did you do, what did you execute

Thanks

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
