Re: Changing Video Mode causes Failure

Yes I played with xrandr. When the screen went blank, I found I could bring it "alive" again by switching to another resolution. Sadly, switching back to 1080p/60 *still* didn't work.

Re: Changing Video Mode causes Failure

No it's being read. My monitor identifier "Samsung50" as well as the specified Intel driver settings are present in Xorg.0.log. Just not the custom mode lines.

Re: Changing Video Mode causes Failure

So the calculated modeline is: Modeline "1920x1080R" 138.50 1920 1968 2000 2080 1080 1083 1088 1111 +hsync -vsync I added this to my monitor section and commented out the others. However after rebooting I do not see "1920x1080R" anywhere in Xorg.0.log. Any thoughts on why? I wasn't expecting to use ...

Re: Changing Video Mode causes Failure

As I mentioned above, I mis-titled this thread. The video mode isn't changing. The option for "separate playback and menu modes" is *not* selected. I verified this at one point, playing some low resolution videos and confirming in the TV that the output was 1080p/60. I sure hope it's something in My...

Re: Changing Video Mode causes Failure

As a test I renamed xorg.conf and let X autoconfigure. It picks 1080p/60 by default. No help there. X auto-probes six different 1080p modes on this TV. I extracted them and tried to set them up in xorg.conf. Unlike my other front ends, somehow this didn't display the manually defined ModeLines in Xo...

Re: Changing Video Mode causes Failure

Yes, the TV turns off awhile after displaying "invalid mode." Pulling and reinserting the HDMI cable does nothing. The host is still running in this state. I experimented using xrandr to change modes after the error: xrandr -d :0 --output HDMI2 --mode 1280x1024 This *did* make the screen come alive ...

Display Randomly Crashes

I clearly have the wrong title on this thread. The video mode is not changing. The TV displays 1920x1080/60 regardless of the stream I am playing. This is my first time working with Ubuntu. I had installed ubuntu-desktop thinking it was needed. It isn't. I uninstalled it. I went back to try the open...

Re: Changing Video Mode causes Failure

I'll try and debug this more. I have already looked at Xorg.0.log as well as mythfrontend.log. I didn't see anything.

The weird thing is I already have a working frontend on this TV and it too has Intel video.

Re: Changing Video Mode causes Failure

The video is integrated Intel like I have on my working frontends. The playback is completely solid when attached via HDMI to a computer display. It's only when attached to my Samsung TV that the problem occurs.

I will play with the refresh rate setting.

Re: Changing Video Mode causes Failure

The "Use Separate Video Modes" option was unchecked. I checked it and selected 1080p for both menus and playback. I left refresh at auto. The problem still happens. I went in and out of several streams with different native resolutions. Is there some other setting you are talking about? Should I set...

Re: Changing Video Mode causes Failure

Damn. Nope, TV still erratically displays "Invalid Mode". Going in and out of recording, live TV and videos, eventually it shuts down.

Now I really am out of ideas. If anyone has any thoughts, I'd love to hear them

Re: Changing Video Mode causes Failure

Sorry if I'm spamming here. But I post questions, think about it, and find my own answers. I think this was an interaction between the paint engine and video profile. The paint engine was set to QT. Setting it to auto allowed me to select the VAAPI video profile. Under QT, VAAPI playback would fail ...

Changing Video Mode causes Failure

I have a new small X86 single board computer. Ubuntu 18.04.03 and Myth 29. Seems to have an issue when switching video modes. Eventually when playing different video streams at different resolutions my Samsung TV says "Invalid Video Mode" and refuses to display anything. When I plug it into a comput...

Re: X Crashes Leaving Live TV

I'm going to start a new thread. I think this has something to do with X changing video modes. Other than this issue it's a nice solid front end.

Re: X Crashes Leaving Live TV

Nope. I was able to go in and out of Live TV a few times. But finally the TV displays "Invalid Mode. Change Device Resolution." Nothing short of a hard boot would fix it. Unless someone has another idea, I guess I'm going to try reinstalling Ubuntu and Myth. This is my first experience with Ubuntu a...
