System User's Guide: Operating System and Devices
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:
- Local consoles
- Remote consoles
- Bitmap and character-display
- Xterminal systems running on a host system on the network
Figure 1. CDE
Interface Points. This illistration shows the connection points
between a console, a network, a bitmap display, a charactor display, and a
workstation.
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:
- Support XDMCP and the -query command-line option.
- Provide xhost permission (in /etc/X*.hosts) to the
terminal host.
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
- If the /etc/dt/config/Xservers file does not exist,
copy the /usr/dt/config/Xservers file to the /etc/dt/config directory.
- If you have to copy Xservers to /etc/dt/config,
you must change or add the Dtlogin.servers: line in /etc/dt/config/Xconfig to be:
Dtlogin*servers: /etc/dt/config/Xservers
- 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
- Reread the Login Manager configuration files.
Adding a Character-Display Console if a Bitmap Display Exists
- If the /etc/dt/config/Xservers file does not exist,
copy the /usr/dt/config/Xservers file to the /etc/dt/config directory.
- If you have to copy Xservers to /etc/dt/config,
you must change or add the Dtlogin.servers: line in /etc/dt/config/Xconfig to be:
Dtlogin*servers: /etc/dt/config/Xservers
- Edit the line in /etc/dt/config/Xservers that starts
the Xserver to read:
* Local local@none /path/X :0
- Reread the Login Manager configuration files.
