XMSM(1)

NAME
xmsm/xmsession - X session manager

SYNOPSIS
xmsm [options]
xinit xmsession
xdm -session xmsession

DESCRIPTION
XmSm is a Motif based session manager for EMWM. In provides screen locking, workspace configuration settings and shutdown options. It is also responsible for starting the window manager (emwm), the application launcher (xmtoolbox) and other, user defined applications.

USAGE
XmSm is normally started by the accompanying xmsession initialization script that sets up the environment, redirects stdout and stderr to ~/.xmsession.log, loads ~/.Xresources and sources ~/.Xprofile before running the session manager.

The xmsession script itself should be invoked either by a display/login manager like xdm, or the xinit utility.

~/.Xprofile is the startup file for X sessions and analogous to the ~/.profile file where user specific environment variables may be set.

 ~/.sessionetc is a shell script that is processed in a separate shell, and may be used to start user-specific programs.

-version
    Print version info and exit.

IMAGE FILE FORMATS
Any image file formats supported by the Motif widget toolkit may be specified. At the time of writing these include X pixmap/bitmap, PNG and JPEG images.

FILES
~/.sessionetc
~/.xmsession.log

SIGNALS

xmsm responds to SIGUSR1 by engaging screen lock.

CAVEATS
The xmsm binary must be setuid root for screen locking and shutdown/reboot functionality, it discards root privileges at startup and restores them only during password check and when executing system commands.

XmSm does not implement the ICCCM session save/restore protocol.

The X screen saver extension is used for timed locking and blanking, but there are no graphical screensavers provided by XmSm.
