When I start a progamme before going to X-windows
I don't understand this distinction - you are starting the program from the text-mode?
I have turn off all screen saver and power management settings in Linux FC4 as below
"below" where? How did you turn off all power management and screensaver settings?
Does this happen for just one program or for all programs?
Do you start the program in the command line and then x-windows loads and then the screen suspends?
When you move the mouse, or touch a key, the screen returns?
The normal way to disable the screensaver in FC4 (Gnome) is:
main menue > desktop > preferences > screensaver
click the "mode" button, and select "disable screensaver".
Is this what you did?
If this is an acpi/apm suspend, you can turn these survices off on the kernel line in grub.conf or by using:
main menue > desktop > system settings > server settings > services
highlight the service you want to stop and click "stop".
Which did you do?
Aside: please put your location and distrbution in your profile. Thanks.
