Certification Objective 3.04—Configuring Devices

Exam Objective 3.4: Use the Xorg configuration files or kdmconfig utility to configure the keyboard, display, and mouse devices for an x64 and x86-based system.

You can use the kdmconfig command to configure or unconfigurc keyboard, display, and mouse devices for OpenWindows and internationalization. This command can be used for any of the following tasks:

• To configure or unconfigure the /etc/openwin/server/etc/OWconfig file with the keyboard, display, and mouse information that is relevant to a client's machine on x86-based systems.

• To set up the display, pointer, and keyboard entries in the /etc/bootparams file on a server machine. The information that you enter is stored in the /etc/bootparams file, which contains one entry per client. The entry for a client contains the client's name and the values for the boot parameters for that client. Diskless clients, while booting, retrieve this information by issuing requests to the server running the rpc.bootparamd.

• To set up the monitor, keyboard, display, and pointer keywords in a system identification configuration (sysidcfg) file. When a diskless client boots for the first time, or a system installs over the network, the booting software tries to obtain the configuration information about the system, such as the system's root password or name service, first from a sysidcfg file and then from the name service databases.

The kdmconfig command has the following syntax:

    kdmconfig [-fv] [-s <hostname>]-c | -t | -u | -d <filename> 

The command will display screens for you to enter the information. The options are described here:

• -c. Execute the program in the configuration mode used to create or update the /etc/openwin/server/etc/OWconfig file. It then displays the screens for you to enter the information.

• -d <filename>. This option is used to create a system configuration identification file that will be used when a diskless client boots for the first time or when you install a system over the network. It is used to avoid prompts for the user and provide a totally hands-off booting process. This command displays the same screens as -c option. The argument <filename> specifies the system identification configuration filename under which the information will be saved.

• -f. Forces screen mode; no network probing will be performed. This option can be used when you want to debug the client's configuration environment.

• -s <hostname>. This option is used to set up configuration information on this machine for the diskless clients.

• -t. Run the command in test mode.

• -u. Unconfigure the system.

• -v. Enable verbose mode.

If you issue the kdmconfig command without any options, it will edit the configuration information from the OWconfig file — that is, it will run like -c option.

You can also use the following commands to reconfigure the system:

    /usr/X11/bin/xorgconfig    /usr/X11/bin/Xorg -configure 

As mentioned previously, the services at the init phase of the boot process are started by the SMF facility svc.startd. Nevertheless, the /etc/rc<n>.d continues to be started as well, for backward compatibility reasons.
