### Configuration Instructions for HP-UX Systems ###
|
|
####################################################
|
|
|
|
There are two ways to start the desktop:
|
|
|
|
|
|
* You can manually start the desktop Login Manager. The advantage
|
|
of using this method is that you will not have to edit
|
|
/etc/inittab.
|
|
|
|
* You can enable the system to automatically start the desktop
|
|
when the system is rebooted. This is done by editing
|
|
/etc/inittab.
|
|
|
|
Removing the Developer's Conference CDE Desktop
|
|
===============================================
|
|
|
|
It is imperative that Snapshot 1 and Snapshot 2 desktops do not
|
|
co-mingle. Installers and users should ensure that old clients and
|
|
configuration files are exited or removed.
|
|
|
|
|
|
Upgrading systems in a networked environment
|
|
--------------------------------------------
|
|
|
|
If CDE is installed in a network environment, it is imperative that
|
|
all systems be upgraded at the same time.
|
|
|
|
|
|
Removing the Snapshot 1 desktop
|
|
-------------------------------
|
|
|
|
Installers are advised to remove the Snapshot 1 Desktop files from
|
|
their systems. Those clients and files are obsolete.
|
|
|
|
|
|
Stopping Desktop clients before installing Snapshot 2
|
|
-----------------------------------------------------
|
|
|
|
If the Snapshot 1 desktop is not removed, ensure that all desktop
|
|
clients are inactive before installing the Snapshot 2 desktop. If the
|
|
desktop was started via /etc/inittab, issue the telinit command to
|
|
stop dtlogin and any other desktop client.
|
|
|
|
|
|
Removing the users's .dtprofile and .dt directory
|
|
-------------------------------------------------
|
|
|
|
It is strongly advised that all CDE users on the system remove or
|
|
rename their .dt directory and their .dtprofile. The Snapshot 2
|
|
Desktop is not compatible with the Snapshot 1 Desktop versions of
|
|
these files.
|
|
|
|
If users have customized their .dt/dtwmrc file and want to keep it,
|
|
they will need to cut and paste the appropriate pieces into the new
|
|
dtwmrc provided.
|
|
|
|
|
|
|
|
Before You Start the Desktop (HP-UX)
|
|
======================================
|
|
|
|
Special Configurations
|
|
----------------------
|
|
|
|
If your system has one of these special configurations, you may need to
|
|
edit certain Login Manager files before starting the desktop. See
|
|
chapter 2 of the Getting Started Guide:
|
|
|
|
|
|
* If the system console is a non-bitmap device.
|
|
|
|
* If the system is an X terminal or a host for X terminals.
|
|
|
|
* If the system has more than one display.
|
|
|
|
|
|
|
|
The Subprocess Control Daemon
|
|
=============================
|
|
|
|
If you are working in an environment where a CDE Desktop action needs
|
|
to start an application on another workstation running CDE, the
|
|
Subprocess Control Daemon configuration must be completed on both
|
|
workstations.
|
|
|
|
1. Log in as root.
|
|
|
|
2. For authentication, the user's home directory on a remote system
|
|
must be mounted to the local system.
|
|
|
|
3. To run an application with a WINDOW_TYPE of NO_STDIO (see Appendix
|
|
A, Advanced User's and System Administrator's Guide), you will need
|
|
to provide NFS-access by the local (client) system to the remote
|
|
(application server) system's /var directory (if /var is a distinct
|
|
volume), or / directory (if it is not). The mount point must be
|
|
/nfs/<remote_host>/var (again, if /var is a distinct volume) or
|
|
/nfs/<remote_host>/ (if it is not). Export the appropriate
|
|
directory in /etc/exports on both the local and remote hosts.
|
|
|
|
|
|
To Start And Stop the Desktop Manually
|
|
======================================
|
|
|
|
To Start the Desktop:
|
|
--------------------
|
|
|
|
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 Stop the Desktop:
|
|
--------------------
|
|
|
|
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 parent 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.
|
|
|
|
|
|
To Enable and Disable Desktop Auto-Start
|
|
========================================
|
|
|
|
When your system is configured to start the desktop automatically, the
|
|
desktop Login Manager runs when the system is booted.
|
|
|
|
To start the desktop automatically, you must edit /etc/inittab to:
|
|
|
|
* Add a line that starts the CDE Desktop.
|
|
|
|
* Set the default run level to the run level assigned to the CDE
|
|
Desktop.
|
|
|
|
NOTE: Edit /etc/inittab very carefully.
|
|
Errors in the file can prevent the system from booting
|
|
successfully.
|
|
|
|
|
|
To Enable Desktop Auto-Start
|
|
----------------------------
|
|
|
|
1. Log in as root.
|
|
|
|
2. If you are running HP VUE, shut it down by entering:
|
|
|
|
/etc/telinit <n>; exit
|
|
|
|
where <n> is a run level assigned to the console and not
|
|
assigned to HP VUE or to halting the system. You can find a
|
|
run level by examinining the lines beginning with cons and vue
|
|
in /etc/inittab. For example, the following lines indicate
|
|
that you can use run levels other than 3, 4, or 6.
|
|
|
|
halt:6:wait:/usr/lib/X11/ignition/shutdown.ksh
|
|
cons:012456:respawn:/etc/getty -h console console
|
|
vue :34:respawn:/etc/vuerc
|
|
|
|
|
|
3. Make a backup copy of /etc/inittab.
|
|
|
|
4. Open /etc/inittab for editing (in a diskless cluster, /etc/inittab
|
|
is a context-dependent file).
|
|
|
|
5. Look for the line that sets the default run level (starting with
|
|
init:). Set the default run level to 5.
|
|
|
|
init:5:initdefault:
|
|
|
|
|
|
6. Add a line that starts the desktop at that run level:
|
|
|
|
dt :5:respawn:/usr/dt/bin/dtrc
|
|
|
|
|
|
To Disable Desktop Auto-Start
|
|
-----------------------------
|
|
|
|
You can restore a console by changing to a run level assigned to a
|
|
console and not assigned to the desktop.
|
|
|
|
|
|
Switching Between CDE and HP VUE
|
|
--------------------------------
|
|
You can switch back and forth between CDE and HP VUE by executing:
|
|
|
|
/etc/telinit <n>; exit
|
|
|
|
|
|
where <n>=3 switches to HP VUE and <n>=5 switches to CDE.
|
|
|
