Wow... thank heavens. I can also very that the patch from Comment #53 has solved this bug that has been driving me nuts for weeks. I would lose my entire X session every single day as soon as the screen blanked... quite troublesome when you're trying to make linux work as your daily drive, haha.
I had to learn how to patch a .deb file properly in the process, but that was worth it too.

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/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
