Give the native keyboard library a chance to initialize itself and

determine whether or not all is well. Use that opportunity in the Linux
keyboard library to determine whether or not we can open a connection to
the X server, and if not, disable the library rather than throwing a
RuntimeException the first time we are called and generally sticking a
fork in the whole program.
