[TriLUG] Stopping Screen blanking on MythTV?

[David A. Cafaro]

So, I've got MythTV up and running with my four tuners (two analog,  
two HD), and everything is working great, but the screen keeps going  
blank to conserve energy.  I've tried a few things to disable energy  
saver and screen blanking, but somehow I'm missing something.

Given this configuration (Fedora Core 6, Default Fedora Gnome, nVidia  
hardware drivers, and MythTV 0.20.2) what all should I set to make  
sure the screen is always on when I turn on the TV?

Thanks for any suggestions,
David
