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, --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 which will be added to the command line invocation
           of icewm. This can be set in the env file.
