Setting up the connection with the X Window System

The Framework uses graphics and windows. On Solaris, this means it will use the X Window System. You must set up the window system by specifying the monitor on which the windows must appear. This is not only necessary for the Framework, but for every program that uses the X Window System.

If you're using a shell created by xon or if you did not log in to another computer at all, you don't need to change anything and you are ready to start the Framework. In this case you can skip the rest of this section and continue reading at section 2.2.2.

The monitor that will be used by the X Window System is determined by the DISPLAY environment variable in your shell. If your shell is csh or tcsh for example, you can display the value of DISPLAY by typing

echo $DISPLAY

If you're using one of these shells and you are sitting behind ford, it must have the value ford:0. You can set this value by typing

setenv DISPLAY ford:0

If the DISPLAY environment variable has an incorrect value when you try to open a window, you may get an error message saying ``Client is not authorized to connect to server'', or the window may open on somebody else's monitor.
