I have a dual monitor setup with two TVs. Everything was working great, then my receiver died. I have everything except mythtv working again. The video card has one HDMI output and one DVI output which gets converted to HDMI. I had to swap the cables to get sound working (I can only get sound working over DVI, not HDMI). Now mythtv always starts on the wrong TV. I have an nvidia card and driver. The desired TV is set as primary in nvidia-settings. I tried using "mythfrontend -display :1" , -display DVI-D-0, with and without quotes, but it always "Abort (core dumped)". Xinerama is off.
mythfrontend -display :0 will open the frontend on the wrong TV. If I disconnect the HDMI from the wrong TV then mythtv starts up on the correct TV. Display: Screen 'HDMI-0' not found, defaulting to primary screen (DVI-D-0).
There has to be a better way than unplugging the HDMI cable every time I start mythtv.

Re: mythfrontend runs on wrong TV
When I plugged the HDMI cable back into the wrong TV mythfrontend crashed again.

Re: mythfrontend runs on wrong TV
I think your syntax is wrong..
Years back I used this in script to start mythtv on the second screen.
I was running each screen as separate Xscreens.
#determine num X screens
number=$(xdpyinfo | grep 'number of screens' | cut -c '22-')
if [ $number = 2 ]; then
ARGS="-display :0.1"
else
ARGS="-display :0.0"
fi
The audio problem could be related problem in selecting the right audio codec in Nvidia card..
At least Nvidia have documentation that is second to none & things typically work exactly as stated.
Have you read up the HDA Azalia etc audio document from NVidia?

Re: mythfrontend runs on wrong TV
I may have misunterstood the problem, if so my apologies.
Can you just set which screen you want to use from Setup -> Appearance -> Theme/Screen Settings -> Display on screen
I use this when I have multiple screens attached and want my frontend on a particular screen.

That fixed it. Thank you, I had looked around, but hadn't found it.

If you're happy with the fix could you possibly added [Solved] to the subject line in the first post?

Re: mythfrontend runs on wrong TV
I'm glad it worked and I hadn't misunderstood the problem
