NAME

icewm-session - X.Org session manager provider with IceWM

SYNOPSIS

icewm-session [OPTIONS]

DESCRIPTION

icewm-session is an implementation of a X.Org session manager and can
be run from a X11 session setup. It runs icewm as default window
manager and controls the life cycle of related support applications.

OPTIONS

SPECIFIC OPTIONS

-c, --config=FILE
Let IceWM load preferences from FILE.

-t, --theme=FILE
Let IceWM load the theme FILE.

-i, --icewm=FILE
Use FILE as the IceWM window manager.

-o, --output=FILE
Redirect all output to FILE. A leading tilde or environment
variable is expanded.

-a, --alpha
Use a 32-bit visual for translucency.

-b, --nobg
Do not start icewmbg.

-n, --notray
Do not start icewmtray. This is only applicable if IceWM was
explicitly configured to use an external icewmtray process.

-s, --sound
Also start icesound.

GENERAL OPTIONS

-d, --display=DISPLAY
Use DISPLAY to connect to the X server. If this option is
missing then DISPLAY is read from the environment variable
"DISPLAY".

--sync
Use a slower synchronous mode communication with the X11 server.

-h, --help
Give a list of all supported options and exit.

-V, --version
Print the program version and exit.

-C, --copying
Print copying permissions and exit.

DEBUGGING OPTIONS

-v, ---valgrind
Let "/usr/bin/valgrind" run icewm. Thoroughly examines the
execution of icewm.

-g, ---catchsegv
Let "/usr/bin/catchsegv" run icewm. Gives a backtrace if icewm
segfaults.

USAGE

On startup icewm-session executes the following steps. From the file
env in the configuration directory it loads additional environment
variables, if that file exists. Then it will start icewmbg to manage
root background colors and images. It may also start icesound, if
this was enabled at configuration time. Then icewm is started.

If there exists an executable script startup in the configuration
directory, it will be executed. It may contain commands to initialize
X11 settings with xset, load keyboard configuration, start a
compositing manager like compton and load system tray applications.

When icewm exits, icewm-session will execute a shutdown script, if it
exists in the configuration directory. When this finishes, icewm-
session will terminate icewm, icewmbg and icesound. Finally, icewm-
session will exit.

If the icewm process crashes then icewm-session will attempt to
restart it. If two such crashes occur in a short period, then icewm-
session will attempt to popup a dialog using either yad, xmessage,
kdialog or zenity. This dialog presents a choice between restarting
icewm, starting a terminal, or abort execution of icewm-session.

ENVIRONMENT

ICEWM_OPTIONS
A space separated list of options that will be added to the
command line invocation of icewm. This can be set in the env
file.
