#12 Muffin *requires* access to graphical interface

[Anonymous]

Muffin's -nw switch is broken. It doesn't create windows (correct). However it still loads classes and makes instances which require connections to a GUI. As a result when you do:

java -jar muffin-0.9.3a.jar -nw

- on MacOS X, this doesn't work unless you have the GUI running, and a Muffin app icon annoyingly appears in your dock.

- on Solaris (and I imagine other X boxen) if you run this from a terminal with X not running, you get:

This is just wrong. Muffin should be launchable from a CLI and not *have* to require ANY GUI resources whatsoever. But it does require them right now.

I think muffin is now a dead project. Too bad.

But here is the trick that I use, make a vncserver, and give
muffin the DISPLAY of that server.
