This is more or less true for all (Intel?)-Linux systems capable of DPMS.
For text mode (simply execute at bootup):
echo -n "Setting DPMS for text console: "
setterm -blank 5 -powersave on # dpms on
echo -en "\033[9;8]" # suspend after 10 min
echo -en "\033[14;10]" # off after 30 min
echo "done."
And for X11 (in /etc/X11/XF86Config):
Section "Device"
Identifier "Videokarte"
VendorName "Matrox"
BoardName "Millennium"
ChipSet "mga2064w"
VideoRam 4096
Option "power_saver"
EndSection
[snip]
Section "Screen"
Driver "svga"
Device "Videokarte"
Monitor "Bildschirm"
DefaultColorDepth 16
BlankTime 5
StandbyTime 8
SuspendTime 10
OffTime 15
Subsection "Display"

As you can see this is for a Matrox Millennium, the monitor is a Belinea
10 70 50 (DPMS capable). The settings in the Section "screen": Blank-,
Standby-, Suspend- and OffTime have defaults like the 'setterm' for the
text mode. The XF86Config is well documentated, the 'setterm' is not. I
read in the news that you have to read the source of
'drivers/char/vesa_blank.c' in the kernel tree in order to get these codes.
For me those work well an the screen is activated trough key press or mouse
mouvement (gpm on the console).
