This depends on the X video driver.

For example, with an Intel video card (and recent enough driver; mine is
2.7.1), you can switch between three settings with the xrandr tool:

  $ xrandr --prop
  ...
          PANEL_FITTING:  full_aspect
                  supported: center       full_aspect  full
  ...
  $ xrandr --output LVDS --set PANEL_FITTING center
  $ xrandr --output LVDS --set PANEL_FITTING full
  $ xrandr --output LVDS --set PANEL_FITTING full_aspect

BIOS settings and hot keys (such as Fn+F8) usually have no effect, since
the Linux kernel takes over and doesn't let the BIOS do its thing, and
for good reasons (changing the hardware state behind the X.org driver's
back may lead to problems and crashes).
