# Description: Acts as a window-manager selector for vnc/freenx sessions

# TODO: - use retval in the case that Xdialog fails to display some message/log
#       - remove use of retval for window close and cancel button as they're disabled
#       - support a nicer way to add wm's to the radiolist
#       - a custom pekwm config so that there are no clicky menus and such

# Set desktop default size
xrandr --output default --mode 640x480

# Start pekwm and keep its pid
pekwm &
PEKWM_PID=$!

# Offer a Xdialog session selector
Xdialog --title "Session Selection" \
        --no-cancel \
        --no-close \
