I would have never really pushed to get this to work, but I needed to have xwindow working for a class that I am taking... After all the work I put in I figured I would give a few pointers that took many hours to figure out (mostly because of my unix ignorance). First of all download the files from xfree86 download. I put all the files into a folder called xfree86 and stashed it onto my harddrive. I then fired up the terminal and got to the xfree86 directory. Next I entered
sudo perl Xinstall.shI tried it the first 2 times with out sudo and it did not work very well. After this runs go to and download the newer XDarwin. This runs rootless (this means that OS X is still visible in the back ground). It takes a little while for the whole thing to load, but it seems to work. Granted I do not know much about this whole thing... but it may be nice to know if you are like me, that using Sudo makes the install actually work!
