Quick Tip: X Server standby

21 October 2009 No Comment

Sometimes you need standby for your Xorg server and sometimes not (surveillance applications don’t need it). I will try to show you in several lines how you can configure that.

To control standby for your monitor you need to see if you have enabled Display Power Management Signaling enabled.

For that try to run following command in a xterm

$xset q
DPMS (Energy Star):
Standby: 1200 Suspend: 1800 Off: 2400
DPMS is Enabled
Monitor is On

if is not enabled just run

$xset +dpms

To set standby, suspend and off parameters run
$xset dpms X Y Z
where X is standby time, Y is suspend time and Z is off time all in seconds.

To set that at every Xorg boot then you should add the following lines to your xorg.conf
Section “ServerFlags”
Option “blank time” “150″
Option “standby time” “300″
Option “suspend time” “600″
Option “off time” “1200″
Option “dpms” “true”
EndSection

If you want to disable DPMS standby then put this configuration in your xorg.conf

Section “ServerFlags”
Option “blank time” “0″
Option “standby time” “0″
Option “suspend time” “0″
Option “off time” “0″
Option “dpms” “false”
EndSection
