Does X11 work with a previously installed version of XDarwin?
We recommend you back up and move aside your previous installation of XDarwin and then install X11 for Mac OS X. A few people have been able to get X11 for Mac OS X and XDarwin to co-exist. Q: I don’t see /Applications/Utilities/X11.app after installing. A: Make sure you install the X11.pkg, not just the X11SDK.pkg. Q: I do not see an xterm startup when launching X11.app. A: A default xterm will launch if you did a clean install and are using the standard xinitrc environment. See xinitrc related question above.
