You can adjust it in xorg.conf or with xset(1). The option lines
below do the magic. For CRT monitors I like to stagger the times a
bit to minimize thermal cycling damage. blank/standby/suspend/off get
set to 10/11/12/13 minutes. For laptop LCD's it hardly matters. I
just turn the sucker off in one go and with a shorter timeout.
>From my fc5 xorg.conf file:
Section "ServerLayout"
# Identifier "Default Layout"
Identifier "ancho, ATI Radeon-200M,builtin WXGA LCD"
Screen 0 "Screen0" 0 0
InputDevice "Keyboard0" "CoreKeyboard"
InputDevice "Synaptics" "CorePointer"
InputDevice "Mouse0" "AlwaysCore"
# added these next 4 -wsr
# LCD monitors seem to only have two modes, on/off
# don't bother going through all the intermediate modes.
Option "blank time" "5" # 5 minutes
Option "standby time" "0" # disable
Option "suspend time" "0" # disable
Option "off time" "5" # same as blank time.
