This question came from our site for professional and enthusiast programmers.

which program is inducing the black screen - most likely something like xscreensaver or some power manager. I have xfce4-power-manager - there I just switch to presentation mode. – epsilonhalbe Apr 28 '13 at 17:58
It should come from my X server, but I want to know if I can do something with my xmonad configuration if write some code there. I'll check this if know other way thanks – Azd325 Apr 28 '13 at 18:15

I have these lines in my ~/.xinitrc file:

# turn off Display Power Management Service (DPMS)
xset -dpms
setterm -blank 0 -powerdown 0

# turn off black Screensaver
xset s off

This prevents the display from turning off during watching a movie (I'm also using XMonad).

But I think is better if I put this in a script and used if I need it because I think in the xinitrc is not the best place for it. If every time this dpms disabled is – Azd325 Apr 29 '13 at 13:36
