Hi Everyone, I'm glad to have found this thread (Many thanks to ToZ in forum.xfce.org): https://forum.xfce.org/viewtopic.php?id=9391
My problem is I read so many possible solutions that I really don't know what to do. I have an intel onboard graphics card and if I turn off TV i have blank screen when later I switch it on again (Xubuntu 14.04) What is the procedure you reccomend me to do? From last posts here it seems to be a fixed releaded, how do I install? I've make a recopilation of all the possible solutions I've read here: ****FIRST - Use this script when problem happends: ============================== #!/bin/sh #Fix TV state when HDMI link is lost. #By Mario Limonciello <email address hidden> 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 ============================== My question is: How can I run the script when HDMI link is lost if I've no video signal? ****SECOND - install gnome-settings-daemon and launch on system boot. It seems too easy to be true, hehe, Do i try? ****THIRD - killall xfsettingsd In my case I can leave computer on with desktop on screen, so I can't do this on any program boot. Whose are the consequences of killing this application on system boot? I've read it can causes an undesired problem, fonts are unreadable (could cause some problem with image quality) ****FOUR - Using DVI cable instead of HDMI I could use a DVI to HDMI cable, at last I can get sound from it, althought I'd prefer maintaining the DVI connection. ****FIVE - downgrade xfce-settings to the 4.11.0 package from Saucy, and locked it at that version (4.11.3 causes the problem). How can I do this? ****SEVEN - Create xorg.conf and add those lines: Option "ConnectedMonitor" "DFP1" Option "UseDisplayDevice" "DFP1" OR Option "ConnectedMonitor" "DFP-0" Option "UseDisplayDevice" "DFP-0" to the "devices" section of /etc/X11/xorg.conf. Only for nVidia cards ****EIGHT - Install a patched 4.11.3 (from my PPA here: https://launchpad.net/~landronimirc/+archive/ubuntu/collection , includes fix_for_bug11107.patch). The person who told this seems to not have solved with this procedure. How can I do this? I mean, How can I Install this patched version. ****NINE - Sean's patch, "fix_for_bug11107.patch" I don't know where to download it from or how to install, it seems to be explained in next option (TEN) ****TEN - Alexander's patch, also Sean's, explained here: For Ubuntu 14.04, this is how your you can build xfsettings with the patches: sudo apt-get install xfce4-dev-tools libexo-1-dev libgarcon-1-0-dev libxfce4ui-1-dev git clone git://git.xfce.org/xfce/xfce4-settings cd xfce4-settings curl https://bugzilla.xfce.org/attachment.cgi?id=5681 > alexander-patch.diff curl https://bugzilla.xfce.org/attachment.cgi?id=5723 > sean-patch.diff Choose a patch to Apply: patch -p1 < <patch> ./autogen.sh && make && sudo make install /usr/local/bin/xfsettings --replace If you wanna to try other patch, first remove what's applied: patch -R -p1 < <applied patch> After playing, remember to remove the installed xfsettings: sudo make uninstall How to test?: - if I do `/usr/bin/xfsettingsd --replace` (4.11.3), then I can easily replicate the crash - if I do `/usr/local/bin/xfsettingsd --replace` (GIT master with Sean's updated patch), the I can no longer replicate the crash Problem: Mirror display is not available. ---------------------------- So I would really thank if someone can lend me a hand Regards and thanks in advance -- You received this bug notification because you are a member of Mythbuntu Bug Team, which is subscribed to Mythbuntu. 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 <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
