[mythtv-users] configuring Xwindows not to blank the screen

[Terrence Martin]

I have noticed that even without a screen saver xwindows seems to be 
blanking the screen from time to time.  I am using XFCE as my window 
manager.

This is irritating for two reasons. One I need to use my keyboard to 
wake the display up, and two blanking the screen seems to displable my 
overscan on my nvidia card.

Any idea how I disable this screen blanking feature?

thanks

Terrence
