# @FUNCTION: make_session_desktop
|

# @USAGE: <title> <command> [command args...]
|
||||
# @USAGE: [--eapi9] <command> [options]
|
||||
# @DESCRIPTION:
|
||||
# Make a GDM/KDM Session file. The title is the file to execute to start the
|
||||
# Window Manager. The command is the name of the Window Manager.
|
||||
# Make a session file to start a Wayland compositor or X window manager
|
||||
# and install it in the appropriate location.
|
||||
#
|
||||
# You can set the name of the file via the ${wm} variable.
|
||||
# @CODE
|
||||
# --eapi9: Switch to getopts style arguments instead of order based
|
||||
# As the naming implies, this is off by default for EAPI=[78],
|
||||
# but mandated by future EAPI.
|
||||
# command: Exec command the session is being started with, also base
|
||||
# for TryExec
|
||||
# with --eapi9: must not contain arguments, use --args for that
|
||||
# --- Options:
|
||||
# name: Name that will be displayed in login managers;
|
||||
# with --eapi9: defaults to PN
|
||||
# --- Additional parameters available using --eapi9:
|
||||
# args: Arguments (binary params) to add to Exec value, separated by
|
||||
# space if multiple
|
||||
# entry: Key=Value entry to append to the session desktop file;
|
||||
# multiple allowed
|
||||
# comment: Comment, defaults to generic text
|
||||
# filename: <filename>.desktop will be created. defaults to <command>
|
||||
# xsession: Create an XSession file (Type=XSession) and install into
|
||||
# /usr/share/xsessions/
|
||||
# default is wayland session into /usr/share/wayland-sessions
