Install the i810switch package; I think it supports the 945GM card. You
will then have simple commands to turn LCD/CRT on and off. I know that
ACPI is well supported on Thinkpads, so it should also be possible to
assign these commands to special keys if you want to do so.
(I have an ASUS laptop with an Intel 855GM graphics card. I regularly
give presentations at different places and i810switch has worked with
every beamer that I have encountered so far.)
