Disable DPMS

[SimpleSi]

I've set up a simple file sharing server in one of my schools but one problem I've got is that the computer is turning the monitor off after a few minutes at the logon screen but I'd like to disable this so that the teachers can see that it is switched on and working.

 

I don't seem to be able to find out how to do this.

 

Ubuntu seems to use "GDM" as the logon manager but I can't find a setting to disable DPMS.

 

Anyone done this before ?

1. locate your xorg.conf file.

2. Find the Monitor section.

3 Find the Options bit and change:

 

 Option "DPMS" "true"

 

to

 

Option "DPMS" "false"

 

If you don't want to go the whole hog and disable DPMS entirely go further down to the ServerLayout section. Alter the following entries to suit.

 

Option "StandbyTime" "10"
Option "SuspendTime" "20"
Option "OffTime" "30"

 

commenting out or removing the option line for a setting will disable it.

Sorry for delay in replying geoff.

 

Last week tried your suggest - switching off DPMS - great - worked - but the system just blanked the screen instead when I came in last week.

 

After a lot of searching and playing I've ended up with

 

xset s off

xset dpms 0 0 0 (Just belt and braces :-) )

 

in my file

/etc/gdm/Init/Default

 

This seems to leave the screen alone but I'll see what happens when I walk in next week :-)

The blanking is probably your screensaver.

 

KDE:

 

Go fiddle with the settings in control panel.

 

Non-KDE:

 

Check the settings for xscreensaver by running 'xscreensaver-demo'.
