Adding and Removing Displays and Terminals for Common Desktop Environment

The login manager can be started from a system with a single local bitmap or graphics console. Many other situations are also possible, however (see the following figure). You can start Common Desktop Environment from:

An Xterminal system consists of a display device, keyboard, and mouse that runs only the Xserver. Clients, including Common Desktop Environment, are run on one or more host systems on the networks. Output from the clients is directed to the Xterminal display.

The following Login Manager configuration tasks support many possible configurations.

Using a Workstation as an Xterminal

From a command line, type:

/usr/bin/X11/X -query hostname

The X server of the workstation acting as an Xterminal must:

Removing a Local Display

To remove a local display, remove its entry in the Xservers file in the /usr/dt/config directory.

Adding an ASCII or Character-Display Terminal

A character-display console is a configuration in which the console is not a bitmap device.

Adding an ASCII or Character-Display Console if No Bitmap Display Is Present

  1. If the /etc/dt/config/Xservers file does not exist, copy the /usr/dt/config/Xervers file to the /etc/dt/config directory.
  2. If you have to copy Xservers to/etc/dt/config, you must change the Dtlogin.servers: line in /etc/dt/config/Xconfig to:

    Dtlogin*servers: /etc/dt/config/Xservers
    
  3. Comment out the line in /etc/dt/config/Xservers that starts the Xserver. This will disable the Login Option Menu.

    # * Local local@console /path/X :0
    
  4. Reread the Login Manager configuration files.

Adding a Character-Display Console if a Bitmap Display Exists

  1. If the /etc/dt/config/Xservers file does not exist, copy the /usr/dt/config/Xservers file to the /etc/dt/config directory.
  2. If you have to copy Xservers to /etc/dt/config, you must change the Dtlogin.servers: line in /etc/dt/config/Xconfig to:

    Dtlogin*servers: /etc/dt/config/Xservers
    
  3. Edit the line in/etc/dt/config/Xservers that starts the Xserver to read:

    * Local local@none /path/X :0 
    
  4. Reread the Login Manager configuration files.
