How to disable power management and screen saver?
 

Hi people

I'm doing some project work for school and help would be very very much apperciated.

I'm got a box running Fedora 5 with gnome as the desktop manager. I written some java code which will start vlc and play videos from other machines.

This box just plays videos (no keyboard or mouse present) so after a while the screen will go to screen saver. Its pretty important I get this to stop. What i've done is diabled apic in setup -> services. and disable screensaver in system -> preferences.
The screensaver stops but the monitor just goes blank, until I put in a mouse and move it around.

Is this a power management issue or a screen saver issue? Can anybody please help because I gotta get this done before my deadline!?!

Thanks

Could be DPMS:
Whats the result of
xset -q

And this for making it permanent on reboot:

Thanks for the reply.

I had Option "DPMS" "True" inside my xorg.conf file and changed to false. It still didn't help though. After about 10 mins the minitor will blank until I move the mouse.

I've played around with a view BIOS settings so I think its a linux screensaver problem. Do you have anymore ideas?

You did restart X Window to make it take effect? Just to be sure..
Well, if gnome or kde has the screensaver disabled then no, the screensaver will not turn on. So its not a "linux screensaver" problem if its disabled in your Window Manager.

Could be a BIOS thing but then you have to look in your bios settings.

Here is the output of the xset -q command.

Ooops you were right, I had forgotten about the X screensaver which is something seperate from WM screensaver. sorry.

xset s noblank
xset s off

?

I'm running short on ideas now :)

I typed in xset s noblank and then xset -q to make sure it did something.

This is what I got

Will I lose these changes when the machine is reboot though? Is there any way to make these changes permanent.

Thanks for all the help
mucho gracias

You should put the lines in
~/.xsession

or
~/.Xsession

(can't remember for gnome, I think its Xsession)

bad news it is still doing the same old thing. about 10 mins and it goes to a blank screen until
I move the mouse.

On my machine just stopping DPMS did the trick so I have no idea anymore..

Can you post the contents of your xorg.conf and xinitrc file?

is in /etc/X11/xorg.conf

and xinitrc is not used because I'm using kde
