It happens via a RANDR event being sent to all X clients when the TV gets turned off. xfsettingsd thinks that it should switch to an internal output, but desktops don't have one. So when the TV comes back on the bus it seems like it's an extra monitor and xfsettingsd gets confused. xfce4-settings(displays): RRScreenChangeNotify event received. xfce4-settings(displays): Refreshing RandR cache. xfce4-settings(displays): Detected CRTC 447. xfce4-settings(displays): Detected CRTC 448. xfce4-settings(displays): Noutput: before = 1, after = 0. xfce4-settings(displays): Output disconnected: HDMI-0 xfce4-settings(displays): Disabling CRTC 447. xfce4-settings(displays): No active output anymore!

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 <[email protected]> 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/~linux-traipu Post to : [email protected] Unsubscribe : https://launchpad.net/~linux-traipu More help : https://help.launchpad.net/ListHelp
