I'm pretty sure this functionality isn't available in 0.6.0. 

The comprehensive class Wx::SystemSettings is ported in wxruby2 which will get you the screen width & height. There is an example in samples/etc/system_settings.rb of how to use the class, but basically you want something like:

Wx::SystemSettings.get_metric(Wx::SYS_SCREEN_X)

ugly, I know ;)
