I have done numerous presentations with a toshiba laptop, the settings in
the bios allow for either simultaneous or detected, ie. both laptop display
and projector or only the projector if its connected.
When using only an external display, (such as a projector) you generally
need a XF86config file written specifically for it, however I've found that
when using simultaneous mode (both laptop screen and projector) no need to
modify the XF86config file, it just displays in the same resolution on the
projector. Are you running a higher resolution on your laptop display than
the projector is capable? Most projectors can display 640 x 480 or 800 x
600, try the lower settings first.
Otherwise you could try the Fn-F4 key combination, on most laptops this
should toggle between simultaneous and detected mode.
If you need a second XF86Config file rename you old file and make a new
one, use a suitable naming convention such as XF86ConfigProj then make a
symbolic link your prefered file before you startx $ln -s ./XF86ConfigProj
XF86Config
