Blanking in console mode is controlled by /etc/defaults/rc.conf:
  blanktime="300"    # blank time (in seconds) or "NO" to turn it off.

Put your override in /etc/rc.conf .

Xorg blanking can be set via "xset".  To see your settings run
"xset q".  If you run "xset" without arguments, you can get hints
on settings:

    For screen-saver control:
         s [timeout [cycle]]  s default    s on
         s blank              s noblank    s off
         s expose             s noexpose
         s activate           s reset

For more detail, see "man xset".

You may also have some window manager screensaver mode to contend

Also as a side, since you're using the xf86-video-mga driver, see
