[Desktop-packages] [Bug 1308105] Re: Xfce resets TV mode to NULL when power cycled
You could probably just use 'xrandr --auto', at least that worked for me. I have actually now a different 'fix', by simply never having the system notice the hdmi-link goes down. I used this wiki-page to fix that for my Intel Haswell-cpu graphics. https://wiki.archlinux.org/index.php/Kernel_mode_setting My final cmdline is now this: video=HDMI-A-1:1920x1080@60e dmr_kms_helper.edid_firmware=HDMI-A-1:edid/tv-edid-data.edid The tv-edid-data file is located in /usr/lib/firmware/edid/ and was derived via 'get-edid'. It actually also seemed to work with the built-in '1920x1080.edid' (saves you retrieving it from your receiver, but I thought it a bit more save to have the actual edid). Just supplying the video-parameter wasn't enough in my case, it failed to actually set the resolution to 1920x1080 (and used 1024x768 instead). Adding the edid-data fixed that (it may even be sufficient to only force-load the edid data). The reason this works is not because it fixes the issue, but because it prevents the hdmi-link from ever going down - as far as the kernel is concerned. -- 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.

What works for me to get some output on my blank screen is to execute 'xrandr --auto' via ssh. That only works when X was started in the first place, which may not be the case if you had booted without the screen on or something like that. -- 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.

[Desktop-packages] [Bug 1268151] Re: DPMS support broken, fails to wake up the monitor after putting it to sleep
I have the same issue with my HTPC, using a brand new Pioneer receiver (and the same with a older Marantz). Switching either of those receivers in standby is probably similar to just pulling out the hdmi-plug. In the Xorg.0.log I see this, when I turn a receiver off: (II) NVIDIA(0): Setting mode "NULL" And when the receiver is turned back on again, I see the normal report of its EDID information. I have another workaround to switch it back on again, since I use x11vnc, I have access to my display server via the network. Using nvidia-settings I can see under "X Server Display Configuration" it has switched the "Resolution" to off. Switching that back to Auto or 1920x1080 also re-enables my screen. When I do that, I see this in the Xorg.0.log: (II) NVIDIA(0): Setting mode "DPY-1:1920x1080+0+0" It'd be nice if it did that automatically when the screen is turned on again. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to nvidia-graphics-drivers-331 in Ubuntu. https://bugs.launchpad.net/bugs/1268151 Title: DPMS support broken, fails to wake up the monitor after putting it to sleep Status in “nvidia-graphics-drivers-331” package in Ubuntu: Triaged Bug description: Also affects nvidia-graphics-drivers-319 The effect is identical to https://bugs.launchpad.net/ubuntu/+source/fglrx-installer/+bug/958279 but with Nvidia instead of AMD/ATI drivers.
