Another way may be inserting the following lines into ~/.xinitrc :

xset s off
xset -dpms

before the statement

exec  ... desktop_manager

such as

exec /usr/local/bin/gnome-session


OR ( every time when required )

in a terminal window of the desktop manager , enter the above xset commands
, which will be effective only up to exit from the X or shutdown of the
computer .

Thank you very much .
