# cat /etc/event.d/control-alt-delete
# # control-alt-delete - emergency keypress handling
# #
# # This task is run whenever the Control-Alt-Delete key combination is
# # pressed. Usually used to shut down the machine.
#
# start on control-alt-delete
#
# exec /sbin/shutdown -r now "Control-Alt-Delete pressed"
2、禁止Fluxbox的Ctrl+Alt+Del
# cat ~/.fluxbox/keys | grep -i exit
# exit fluxbox
# Control Mod1 Delete :Exit

# # started until it is shut down again.
#
# start on stopped rc2
# start on stopped rc3
# start on stopped rc4
# start on started prefdm
#
