how to detect headless mode from code?

Hi!

Can I detect headless mode from code?
(I have some server task implemented in squeak and I want to
automatically quit from image after task is done - but only in headless
mode.)

Thanks, pf

You can access the command line parameters via #getSystemAttribute:

Also, IIRC, the Display extent in headless mode is quite small.
