README file for the X Session Manager (xsm)
|
|
-------------------------------------------
|
|
|
|
xsm is a session manager. A session is a group of applications, each
|
|
of which has a particular state. xsm allows you to create arbitrary
|
|
sessions - for example, you might have a "light" session, a "development"
|
|
session, or an "xterminal" session. Each session can have its own set of
|
|
applications. Within a session, you can perform a "checkpoint" to save
|
|
application state, or a "shutdown" to save state and exit the session. When
|
|
you log back in to the system, you can load a specific session, and you can
|
|
delete sessions you no longer want to keep.
|
|
|
|
Some session managers simply allow you to manually specify a list of
|
|
applications to be started in a session. xsm is more powerful because it
|
|
lets you run applications and have them automatically become part of the
|
|
session. On a simple level, xsm is useful because it gives you this ability
|
|
to easily define which applications are in a session. The true power of
|
|
xsm, however, can be taken advantage of when more and more applications
|
|
learn to save and restore their state.
|
|
|
|
This README file discusses the necessary steps you must take to run xsm. To
|
|
learn more about the details of xsm's functionality, read the xsm man page.
|
|
|
|
Before building xsm, you should make sure you have the following libraries
|
|
built on your system:
|
|
|
|
libICE - the Inter Client Exchange Library
|
|
libSM - the Session Management Library
|
|
libXt - the X Toolkit with support for session management
|
|
|
|
Once you are sure all of the required libraries are built, you are ready
|
|
to build xsm.
|
|
|
|
Before you can run xsm, you must make sure that the following programs are
|
|
built and installed on your system:
|
|
|
|
smproxy - the session manager proxy for applications that don't support
|
|
R6 style session management
|
|
iceauth - handles storing/retrieving ICE authentication information
|
|
rstart - allows xsm to start applications on remote machines
|
|
twm - window manager that support R6 style session management - takes
|
|
care of saving window configurations in a session
|
|
|
|
Note that to install rstart, you will need to have root privileges because
|
|
the program must be installed in a system wide default path.
|
|
|
|
*** rstart and iceauth should be installed on each machine that you expect
|
|
to run applications on that will be part of your session ***
|
|
|
|
Also note that twm is the default window manager that xsm starts up. If you
|
|
would like to use a different window manager, follow the instructions in the
|
|
xsm man page for defining the default startup applications. Be aware that if
|
|
the window manager you choose has not been modified to support R6 style
|
|
session management, window configurations will not be saved in your sessions.
|
|
|
|
Once again, for more information about actually using xsm, please read the
|
|
xsm man page.
|
|
|
|
To learn more about making your applications "session aware", consult the
|
|
X Toolkit Intrinsics documentation.
