You can use the get_screen_size funtion as Dave mentions in a parallel 
thread (but check if your version has the same bug I found, posted to
that
thread).

Alternatavely, I have a DLM which makes direct Xlib calls to the X
server
to determine lots of information on the display, screen and available
visuals. It's rather a heavy-weight approach if all you require is the
screen
dimensions but I could make it available if you like. It does require
a C compiler and an X development environment (basically the X header
files).
