Ah. Wish you had mentioned that earlier. Please pardon me for using you
as an example - I mean no harm, but it might help others who have
questions. If an original question is not answered, simply repeating it is
unlikely to get any more response. If you explain your exact situation,
however, the problem can usually be solved, or at least the question can be
answered.
I must assume that you press a special key on the notebook keyboard
labelled "Fn" or "Function" or something like that, and then you press
either "3" or "F3". This is considerably different from pressing "function
keys", which are the keys labelled "F1" through "F12" at the top of the
keyboard. "Function keys" work just like any other key, which is probably
why the question wasn't being answered -- nobody could reproduce it. If
your notebook actually hooks plain "F3" to switch displays, it is going to
cause a lot of problems with other programs that wish to use "F3" as an
application key.
So, going on the "Function"+"F3" assumption -- The "Function" key is a
special key that keeps any other key pressed from going through the normal
keyboard channels. In the "Function"+"F3" case, the signal is instead
routed either to the BIOS or to the video chip, and tells it to toggle
output _transparently_to_any_underlying_operating_system_.
VNC cannot possibly transmit these kinds of sequences, because they occur
underneath the operating system.
I can think of two possible remedies, but can't guarantee either:
1. Your notebook may have an application that allows you to change display
output. You'd just have to look everywhere in your Start Menu, because
different manufacturers/models put these in different places.
2. Check your bios settings. When you boot the notebook, it will
(hopefully) give a message like "Press DEL to enter Bios" or "Press F2 to
change settings" or something similar. Other keys I have seen used are F1,
ESC, CTRL-ALT-ESC, and just about anything imaginable. DEL, F2, and F1 are
the most common, though. If you can get to your bios, you may be able to
tell it to boot up in external monitor mode (or whichever mode you want).
You will have to do this locally. If you actually need to change the
output mode _while_ remote controlling the notebook, your only hope is
option 1.
Hope that helps,
