[ltp] External video on T61

If you have a NVidia GPU running with nvidia drivers, nvidia-settings
can do more or less anything.

Another way that should work with any GPU or driver is this:
+ configure the screen resolution to whatever the beamer likes
+ reboot
+ at startup/poweron, press F1 to enter the BIOS
+ under config / display declre the VGA connector as primary display
+ plug in a beamer (or, to test, any external monitor)
+ reboot
eventually you also need to do this:
+ before linux starts to boot, switch it off
+ switch on again and eventually close the LCD fast
