What do you use as power manager in fluxbox or any other WMs? I am using xfce4-power-manager but the problem is it doesn't turn off the screen half the times. It's like when it's in mood and I have just boot up my pc, then after the specified time it turns off the monitor but other times it just doesn't work.
xset dpms force off
but that too stays for like a minute. Any ideas/suggestions are welcome.
