: The GET_SCREEN_SIZE keyword to the DEVICE command under X windows will give
: you the size of the entire screen in pixels. I think you still have to link
: to the C program to get the size in mm.

Not if the screen is properly set up. The GET_SCREEN_SIZE gives the screen
size and the !D.[xy]_px_cm give the pixels/cm. From which it is trivial
to extract the size of the screen in cm.
