That is normal - I am not sure either just why there are two<br>
instances, but if you look more closely (ps -ef | grep dm), you find<br>
that the second one is a child of the first one.<br>

I think you will need to reconfigure things so that each of the<br>
outputs is a separate X display. I have never use the "metamodes"<br>
option they way you have to configure two outputs, but I was surprised<br>
to see that it was valid to have both of them as "-0". I would have<br>
thought that what that would do is to make the monitor and TV both<br>
have the same output, rather than have the desktop on the monitor and<br>
MythTV on the TV. But it depends on how your other X config is done -<br>
you can set up X so that the two screens are side by side and you can<br>
then drag mythfrontend to the right from the monitor to the TV. Is<br>
that what you are doing? Anyway, please post the full<br>
/etc/X11/xorg.conf file and more detail about how your current setup<br>
works.<br>
<br>
I think the way you should be setting it up is so that each output is<br>
a separate X display, say VGA on 0, TV on 1 and projector on 2. Then<br>
you would be able to set up each of them in their native best<br>
resolution, and send the desktop to the monitor, and use the -display<br>
option on mythfrontend to choose which of the TV or projector it ran<br>
on. The problem with doing it that way is that you can run out of GPU<br>
RAM running three displays at once, but I think trying for that first<br>
would be the best idea because it the most simple way to do what you<br>
want. And I think it might help with your problem with the progress<br>
bar, as having each display running in native resolution is the best<br>
way to avoid strange problems like that.<br>
<br>
To help work out the best config, it would be useful to also have the<br>
/var/log/Xorg.*.log file(s) after booting with all three display<br>
attached and switched on. Of particular interest is the section at<br>
the start of the log file where it tells you what are the valid<br>
devices and their characteristics, starting with a section like this:<br>
<br>
[ 36.700] (--) NVIDIA(0): Valid display device(s) on GeForce GT 220<br>
at PCI:1:0:0<br>
[ 36.700] (--) NVIDIA(0): CRT-0<br>
[ 36.700] (--) NVIDIA(0): CRT-1<br>
[ 36.700] (--) NVIDIA(0): SONY TV (DFP-0) (boot, connected)<br>
[ 36.700] (--) NVIDIA(0): DFP-1<br>
_______________________________________________<br></blockquote><div><br></div><div>xorg.conf was created by nvidia-settings. What it is essentially doing is creating a single desktop that extends across both monitors. I can drag things across but there is an option to declare the TV as the primary monitor and when I do that Myth starts on that monitor. I have been unable to figure out how it does that. I looked at the code for starting myth on startup and it isn't clear. I think I could modify the metamode line to add the projector and place if off to the right of the TV with its native resolution. I could then shutdown mythfrontend and launch it again targeted to that part of the three monitor desktop that is the projector. If myth responds to the </div><div>--geometry=WidthxHeight+Xoffset+Yoffset command I could use that. I don't know if that works. It did not work for Chrome. Then I could create a desktop icon that launched myth with the appropriate options.
