I would suggest subscribing to the X11 mailing list that Apple has set up.
You will need to download the X11 SDK and install it. The link is just below the X11 download link. Download Fink Commander, it will give you a GUI interface for installing .deb and binaries.
Icecwm can work.
There is an invisible file in your Home directory names .xinitrc. The period at the beginning makes it invisible. This file is one that does intial configuration to xterm.
From the Terminal enter sudo cp .xinitrc .xinitrc.back. Then sudo pico .xinitrc. You will need to enter your Admin password. Pico is an editor, the sudo command allows root access to change files such as this. The first command creates a backup so if all this crews up you can retrieve your config by renaming the .back file.
Pico will open the .xinitrc file for editing. Look at the bottom of the window- there are some commands. You want to enter Control-v to page down. You will see a line that says # start some nice programs. As it is setup at install, tvm is the Window Manager- insert # at the beginning of the tvm line. This "comments it out" meaning that it willl not execute.
If you have downloaded and installed icewm, add:
Code:
source /sw/bin/init.sh
exec /sw/bin/icewm
Any line below the exec will not execute, so you may want to change to order of commands.
Control o writes the file, press return to confirm overwriting the current file. Control X will exit pico
