Instructions for IBM AIX Systems 04/11/94
|
|
=================================
|
|
|
|
The following instructions assume you have already installed the Common Desktop
|
|
Environment according to the Installation Instructions on the CD jacket. If
|
|
CDE is used in a networked environment, all systems should be upgraded at the
|
|
same time.
|
|
|
|
There are two ways to start the desktop:
|
|
|
|
* You can manually start the desktop Login Manager. This method can be used to
|
|
avoid rebooting the system. See the section To Start and Stop the Desktop
|
|
Manually .
|
|
|
|
* You can configure the system to start the desktop automatically upon reboot.
|
|
See the section To Enable and Disable Desktop Auto-Start..
|
|
|
|
Before You Start the Desktop
|
|
============================
|
|
******************************************************************************
|
|
If you have a previous Common Desktop Environment (CDE) version on the system:
|
|
******************************************************************************
|
|
|
|
Advise all CDE users on the system to remove or rename their $HOME/.dt directory
|
|
and their $HOME/.dtprofile. The new files are not compatible with the old
|
|
ones. If users have customized the $HOME/.dt/dtwmrc file and want to keep
|
|
it, they will need to cut and paste the appropriate pieces into the new dtwmrc
|
|
file provided.
|
|
|
|
Become the root user on the system. Make sure all other users on the system
|
|
are logged out of CDE. Kill the Login Manager.
|
|
|
|
cat /etc/opt/dt/Xpid (obtain Login Manager process_id)
|
|
|
|
kill -TERM <process_id>
|
|
|
|
Killing the Login Manager process works no matter how the process was started.
|
|
An alternate method is to stop the system resource control for the desktop.
|
|
This method should only be used if CDE was configured on the system with
|
|
/opt/dt/bin/dtconfig -e. If you don't know how CDE was configured on the
|
|
system, lssrc -s dtsrc will return the status of dtsrc. If no status
|
|
is returned, use the kill method in the previous paragraph.
|
|
|
|
stopsrc -c -s dtsrc
|
|
|
|
Completely remove the /etc/opt and /opt directory structures from the system.
|
|
The install script mentioned in the README should have already given you the
|
|
chance to remove these. Remove the dtsrc subsystem only if CDE was configured
|
|
on the system with /opt/dt/bin/dtconfig -e:
|
|
|
|
rmssys -s dtsrc
|
|
|
|
Default Configuration
|
|
|
|
The Instructions for IBM AIX Systems show basic installation information.
|
|
We recommend following these instructions before doing any personal
|
|
customization work except in the case of the Special Configurations.
|
|
|
|
Special Configurations
|
|
|
|
If your system has one of these special configurations, you may need to edit
|
|
certain Login Manager files before starting the desktop. More detailed
|
|
information is in the CDE Getting Started Guide.
|
|
|
|
* If the system console is a non-bitmap device (e.g. an ascii
|
|
terminal)i, comment out the following line in /usr/dt/config/Xservers that
|
|
starts the Xserver on the console.
|
|
|
|
# :0 Local local@console /path/X [options] :0
|
|
|
|
* If the system is an X terminal or a host for X terminals,
|
|
CDE must be running on the host and X Display Manager Control Protocol
|
|
(XDMCP) must be enabled for the X terminal and must direct the Xterminal to
|
|
contact the Login Manager on a specified host.
|
|
|
|
* If the system has more than one display, see Configuring
|
|
Multiple Displays in the CDE Getting Started Guide.
|
|
|
|
To Start and Stop the Desktop Manually
|
|
--------------------------------------
|
|
There are two manual methods to start the desktop:
|
|
|
|
* You can manually start the CDE Login Manager. To use this method, you must
|
|
have permission to log in as root. This method is preferable, because Login
|
|
Manager sets certain environment variables that are needed during desktop
|
|
sessions. See the section Manually Starting and Stopping Login Manager.
|
|
|
|
* You can log in using conventional methods, and then manually run the
|
|
CDE Session Manager, which starts a desktop session. See the section
|
|
Manually Starting and Stopping Session Manager.
|
|
|
|
Manually Starting and Stopping Login Manager
|
|
--------------------------------------------
|
|
To manually start Login Manager:
|
|
|
|
1. Log in as root.
|
|
|
|
2. Enter:
|
|
|
|
/usr/dt/bin/dtlogin -daemon
|
|
|
|
This starts the Login Manager and displays the Login screen.
|
|
Logging in starts a desktop session.
|
|
|
|
To manually stop Login Manager:
|
|
|
|
When you stop the Login Manager, you automatically kill all X servers and
|
|
desktop sessions that it started.
|
|
|
|
1. In a terminal emulator window, log in as root.
|
|
|
|
2. Obtain the process id of the Login Manager by entering:
|
|
|
|
cat /var/dt/Xpid
|
|
|
|
3. Kill the Login Manager by entering:
|
|
|
|
kill -TERM <process_id>
|
|
|
|
where <process_id> is the value obtained from Xpid.
|
|
|
|
Manually Starting and Stopping Session Manager
|
|
----------------------------------------------
|
|
Using this method
|
|
|
|
* leaves you responsible for setting certain environment variables to values
|
|
required by the desktop if suitable values are not already set in your
|
|
environment.
|
|
|
|
|
|
* allows you to use CDE while others serving from the same system, including
|
|
the console are not.
|
|
|
|
1. Log in. (You do not need to log in as root).
|
|
|
|
2. With no window system running, from the command line enter:
|
|
|
|
/usr/bin/X11/xinit /usr/dt/bin/Xsession
|
|
|
|
HINT: if a .Xinitrc file is enabled, make sure it is NOT starting another
|
|
window manager. Do NOT put the /usr/dt/bin/Xsession in your .profile!
|
|
|
|
Session Manager stops when you log out.
|
|
|
|
To Enable and Disable Desktop Auto-Start
|
|
----------------------------------------
|
|
AIX can be configured to start the CDE Desktop automatically when the system
|
|
is booted. This method starts CDE as the Session Manager for all users on
|
|
the system.
|
|
|
|
There are several ways to do this configuration:
|
|
|
|
* From a command line.
|
|
|
|
* Using SMIT menus.
|
|
|
|
* Using SMIT fastpath.
|
|
|
|
