USAGE="${0##*/} [session]

A wrapper around gnome-session that can be passed to xinit.

Provide the session type in the DESKTOP_SESSION variable,

or as an optional session argument.

Examples:

(launch GNOME from crosh with session in DESKTOP_SESSION)

DESKTOP_SESSION=gnome xinit /etc/X11/xinit/xinitrc ${0##*/}

(launch Unity from an xterm with session as an argument)

${0##*/} ubuntu"

export DESKTOP_SESSION="${DESKTOP_SESSION:-"$1"}"

SESSION='gnome-session'

CINNAMON_SESSION='cinnamon-session'

if [ -z "$DESKTOP_SESSION" ]; then

echo "$USAGE" 1>&2

exit 2

fi

# Cinnamon 2.0 and later uses its own fork of gnome-session

if [ "${DESKTOP_SESSION#cinnamon}" != "$DESKTOP_SESSION" ] && \

hash "$CINNAMON_SESSION" 2>/dev/null; then

SESSION="$CINNAMON_SESSION"

fi

if [ -z "$DISPLAY" ]; then

exec xinit /etc/X11/xinit/xinitrc "$0"

else

exec "$SESSION" --session="$DESKTOP_SESSION"

fi
