CHANGE_LOGIN(8)             System Manager's Manual            CHANGE_LOGIN(8)



NAME
       change_login - control screen blanking and choice of login utility

SYNOPSIS
       change_login

AVAILABILITY
       Available  only  on  Sun  386i systems running a SunOS 4.0.x release or
       earlier.  Not a SunOS 4.1 release feature.

DESCRIPTION
       To prolong the life of your monitor, your Sun386i system turns off  the
       screen  display  if you have not used the keyboard or mouse for 30 min-
       utes or more.  To see the screen again, simply move the  mouse  on  the
       pad  or  press any key.  This feature is normally enabled automatically
       when you log in, but you can control it using the change_login  command
       as explained below.

       This   command  also  determines  whether you log into your workstation
       using the Sun386i login screen, logintool(8) or through  a  traditional
       login: prompt.

       The screen blanking choices available with change_login are:

       1. Logintool and Sun Logo screenblank
              Enables  screen  blanking.   When blank, the system displays the
              Sun logo moving randomly around an otherwise dark screen.

       2. Logintool and video-off screenblank
              Shuts off the video output to your monitor when the screen  goes
              blank.  This is the most efficient type of screen blanking.  The
              Desktop is almost instantly redisplayed when you move the  mouse
              or begin typing.

       3. Logintool and no screenblank
              Retains the login screen, but disables screen blanking.

       4. No Logintool and no screenblank
              Disables both the login screen and screen blanking.

EXAMPLE
       The following is an example of change_login.  Notice you must be super-
       user to use this command.
              example# change_login

              This program will check what login and screenblank
              options are set on this workstation, and allow you
              to choose other options, if you are logged in as superuser.

              Do you want to do this? [y or n]: y

              This workstation is set up to use logintool and
              a screenblank program that displays a Sun logo graphic.

              These are the available options:

              + 1. Logintool and Sun Logo screenblank
                2. Logintool and video-off screenblank
                3. Logintool and no screenblank
                4. No Logintool and no screenblank

              + indicates the current configuration

              You must be logged in as superuser to change the current setting.

       Follow the instructions in Sun386i  System  Setup  and  Maintenance  or
       Sun386i Advanced Administration to shut down and then restart your sys-
       tem.  The setting chosen in the above example will not be enabled until
       you have restarted your system.
