I'm afraid but Sean's patch, "fix_for_bug11107.patch", does not fix the issue for me. I tried with both git-master (d532c0f06d4a629aebf11e8bead63617931001d2) and tag 4.11.2 (e329018189663837f2cd9c50807e4376a852cc88). My patch in turn still works with both said commits.
However, since my patch only addresses the issue's symptoms but not its actual cause, Sean's patch should be further improved instead of just using mine. It's interesting to see that "fix_for_bug11107.patch" already fixes the problem for Raj, which makes me think that there's more to this issue than we understand thus far. Btw, I tried both enabling and disabling the "Configure new displays when connected" feature but that did not have any effect. I'm out of ideas right now. My configuration: Xubuntu 14.04 x64 Kernel 3.13.0-39-generic Intel Core i5-4590S Intel driver 2.99.911-0intel1 Monitor attached with a HDMI-to-HDMI cable -- 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, Ubuntu derivative focused upon MythTV: 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 <[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/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
