It doesn't work on our systems. It just returns the display size of the
default display regardless of what you pass to the DISPLAY_NAME argument
or keyword.

After looking at the code further, it seems there is a bug in
get_screen_size.pro
in both IDL 5.1 and 5.2. The function specifies the DISPLAY_NAME keyword
on 
the WIDGET_DRAW function rather than the WIDGET_BASE function.

If I issue the commands manually and and put the DISPLAY_NAME keyword on 
the WIDGET_BASE function it works as expected. I guess I'll be editing
the .pro
files.


Now, I wonder if doing this sets the X visual to the default?
