I *know* there's something simple I need to do, I just don't know what it is.<br><br>I'm trying to tweak the settings for my nvidia driver controlled display on a plain old TV connected to my frontend system using nvidia-settings.
<br><br>The problem is that since the TV is configured for 640x480, and nvidia-settings doesn't fit on a screen that small, I can't see all the controls. Solution: make it display remotely on my MythTV backend which has a 1280x1024 VGA monitor attached. Simple -- just trot over to the backend and run the command "nvidia-settings --ctrl-display=TV-hostname:0", but this didn't work.
<br><br>I tried "xhost +" followed by the command and still no joy. Tried the reverse by going back over to the frontend and entering "nvidia-settings --display=Backend-hostname:0", with equally dismal results. I even tried variants on localhost and IP addresses.
<br><br>The error message is invariably "ERROR: Cannot open display: 'TV-hostname:0'."<br><br>I can run nvidia-settings on each system, and I can even run it remotely through an ssh-tunnel, but it's too smart and wants to adjust the display that the window is opened on, localhost:10. I even tried "nvidia-settings --ctrl-display=localhost:0 --display=localhost:10", but it wouldn't go for that either.
<br><br>I don't have SELinux enabled (or even installed IIRC), so I don't think that's a factor.<br><br>What am I missing?<br><br>Craig.<br>
