Hi! The XFCE4's maintainer claimed to have merged the patch for this bug here: https://bugzilla.xfce.org/show_bug.cgi?id=11107#c67 on 2016-08-12.
A new version of xfce-settings (4.12.1) has been released on 2016-09-15 so we can assume that the fix is integrated in the release. Note that the patch is not the same as the one I've linked in comment #107. I still have to test the new version. Note also that the 4.12.1 version was not integrated in ubuntu 16.10 so we still have to recompile and install it manually :( -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to nvidia-graphics-drivers in Ubuntu. https://bugs.launchpad.net/bugs/1308105 Title: Xfce resets TV mode to NULL when power cycled Status in Mythbuntu: Confirmed Status in xfce4-settings: Confirmed Status in nvidia-graphics-drivers package in Ubuntu: Invalid Status in nvidia-graphics-drivers-331 package in Ubuntu: Invalid Status in xfce4-settings package in Ubuntu: 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 <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
