kdmconfig(1M)						  System Administration Commands					     kdmconfig(1M)

NAME
kdmconfig - configure or unconfigure keyboard, display, and mouse options for OpenWindows and internationalization SYNOPSIS
kdmconfig kdmconfig [-fv] [-s hostname] -c | -t | -u | -d filename DESCRIPTION
The kdmconfig program configures or unconfigures the /etc/openwin/server/etc/OWconfig file with the keyboard, display, and mouse informa- tion relevant to a client's machine on x86 based systems for Solaris software. kdmconfig can also be used to set up the display, pointer, and keyboard entries in the bootparams(4) database on a server machine or the monitor, keyboard, display, and pointer keywords in a sysid- cfg(4) file. kdmconfig can only be run by the super-user. Upon completion of device selection, kdmconfig prompts the user to test the con- figuration, which is done by running the window system. The kdmconfig program is normally run during installation and upon reboot, but it can also be run from the command line after the system has been installed. When configuring a client during an initial installation or a reconfigure reboot, the sysidconfig(1M) program will invoke kdmconfig with the -c option, and when the user executes the sys-unconfig(1M) program, kdmconfig will be executed with the -u option. Similarly, when you run kdmconfig from the command line, use the -u option to unconfigure the existing OpenWindows configuration. You can then rerun kdmconfig with the -cf options to create a new OpenWindows configuration. To edit the existing configuration, run kdm- config from the command line without options. After each reboot, kdmconfig will be invoked by the system with the -t (test mode) option to ensure autoconfiguration capability and identify possible conflicts between the current configuration and the one recorded in the OWconfig file. OPTIONS
The valid options are: -c Run the program in the configuration mode. This mode is used to create or update the OWconfig file. When invoked in this way, kdmconfig first looks for the relevant configuration information in the bootparams(4) databases. It also takes into account the information returned from device probes, unless the -s option is also used. The bootparams(4) databases avail- able to the client are all of the /etc/bootparams files on servers on the same subnet as the client, provided the server machine is running the bootparamd(1M) daemon. kdmconfig is invoked with the -c option when called by sysidconfig(1M) -d filename Set up a sysidcfg(4) file. This option displays the same screens as the -c option, but the information you specify is saved as sysidcfg(4) keywords (monitor, keyboard, display, and pointer). This enables you to use a sysidcfg(4) file to precon- figure a system's device information and bypass kdmconfig during an installation. filename is the sysidcfg(4) file that is created, and it is created in the directory where kdmconfig is being run unless a path is specified. If filename already exists in the specified directory, the keywords are appended to the existing file. -f Force screens mode. When this option is invoked, no network probing will be performed. This is helpful when debugging the client's configuration environment. Note that the -s option implies the use of -f, bypassing network probing when setting up a server. -s hostname Set up the bootparams(4) database on this machine for the specified client. This option presents the same screens as it does when run on a client, but instead writes the resulting information to the /etc/bootparams file. Also, -s implies the use of the -f option. That is, the program will always present the screens to the user when invoked this way. This option will reconfigure the nsswitch.conf( 4) file to look for a bootparams(4) database on a local server. This option is only available to the super-user. -t Run the program in test mode. In this mode, kdmconfig will use device probe information to determine whether the OWconfig file contains complete and up-to-date information about the keyboard, display, and mouse. If the information is accurate, kdmconfig will exit silently. Otherwise, kdmconfig will prompt for the super-user password and proceed to a normal editing session (as though it had been run without options). -u Unconfigure the system, returning it to an "out-of-the-box" state. In this state, the factory default keyboard, mouse, and display are selected as a result of removing the device configuration entries from the /etc/openwin/server/etc/OWconfig file. This may result in an unusable configuration for the display server. -v Enable verbose mode. Normally, kdmconfig will not produce any output. This option is helpful for debugging, as it records the different actions taken by kdmconfig on stderr. No Options Run without options, kdmconfig is used to edit the current configuration. kdmconfig uses the information from the OWconfig file in addi- tion to information obtained from the bootparams(4) file and from device probes. In other respects, it is similar to using the -c option of kdmconfig. FILES
