There are several versions of X11 for OSX -- the one Apple distributes, and in macports, xfree86 and xorg, both in several variants. Could someone give us a summary of the state of X11 on OSX? What should be used when? Where are we headed? I'm so far not able to start the XFree86 version I installed. The XDarwinStartup man page says, "When run without any arguments, XDarwinStartup will start the Quartz X server if the Core Graphics window server is currently running. Otherwise it will start the IOKit X server." In my case the Core Graphics window server is running, so I try: XDarwinStartup -quartz but it just sits there, and I see the process list has /usr/X11R6/bin/XDarwin.app/Contents/MacOS/XDarwin -quartz -nostartx Doesn't seem to want to run, does it?
