Try this: Forget about the keyboard and use the xrandr command-line
utility to talk directly to the hardware.
xrandr is short for X.org Resize and Rotate. It can do freaky things like
rotate the display from landscape to portrait mode on the fly. In your
case, you can use it to detect available video monitors and clone the
laptop display to the external one. You can optionally specify what
resolution the external monitor should display, in case it's different from
your laptop screen.
Also check out the xrandr man page.
