When you are done using Cygwin/X, press
Alt-F4 to
shutdown the X Server; this is the default key combination to shutdown
the X Server. The -[no]winkill
and
-[no]unixkill
parameters can change the set of
key combinations that will shutdown the X Server. Using the
-unixkill
allows the
Ctrl-Alt-Backspace
key combination to shutdown the X Server, in addition to the default
Alt-F4 key
combination.
