[mythtv-users] How to get rid of power save

[Tobias Luetke]

How do i get rid of linux power save mode?

Since i switched back to geforce TVout from pvr350's i have the problem
that the screen goes black after about 20 mins until i move the mouse.

I use xfce4 and even uninstalled xscreensaver.

I removed support for APM and power management from the kernel.

It looks like xine and mplayer prevent this from happening, but while 
i'm watching something in myth.
