Thanks jkampe68! Attachment 6590 completely fixes the problem for me on Ubuntu and Arch Linux. I've made an AUR package including your patch:

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 <supe...@ubuntu.com> 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 ============================== To manage notifications about this bug go to: https://bugs.launchpad.net/mythbuntu/+bug/1308105/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~mythbuntu-bugs Post to : mythbuntu-bugs@lists.launchpad.net Unsubscribe : https://launchpad.net/~mythbuntu-bugs More help : https://help.launchpad.net/ListHelp
