[root@probe root]# setup_x

It should be noted that the setup_x will detect your hardware and display a graphical selection panel allowing you to specify your X desktop resolution and color depth. It will then exit after writing the appropriate information to /etc/X11/XF86Config. You will then be able to bring up X with the startx command.

The following screen shot shows ethereal, etherape and ipsc running on a Network Security Toolkit probe running X:

The VTWM window manager is used when running a X desktop. You can launch X based applications by right clicking on the desktop to pull up a menu, or by typing the name of the program you want to run in a xterm window.

The VTWM provides virtual desktop space. So, you will only see a portion of the available desktop displayed on your screen. You should see a small black rectangle within a larger blue rectangle at the bottom right corner of your screen. If you drag the small black rectangle around, you can change what portion of the desktop is visible at any point in time.
