By default, Red Hat Linux blanks the screen after an interval of no keyboard or mouse activity (usually 10 minutes). This can be sometimes inconvenient.

To disable screen blanking:

1. Login to the machine as root
2. Open the file /etc/X11/gdm in your favorite editor
3. Scroll down to the section that defines the standard X server. It should look like:

   #Definition of the standard X server.
   [server-Standard]
   name=Standard server
   command=/usr/X11R6/bin/X -audit 0

   Your lines may look slightly different

4. Add the option "-s 0" to the command. e.g.

   command=/usr/X11R6/bin/X -s 0 -audit 0

5. Open the file /etx/X11/xorg.conf in your favorite editor
6. Comment out the DPMS option lines:

      Option           "dpms"

   and/or

      Option           "DPMS" "true"

   by placing a "#" sign at the start of the line(s).

7. Restart the X server (ctrl-alt-backspace, log-off/log-on. In some cases a reboot may be necessary).
8. If the screen is still blanking, login as the user and execute xscreensaver. Use the xscreensaver interface to disable any screensaver/screen blanking.
