I just did a complete installation of X11 from Cygwin 1.7 setup.exe.
But when I try to start the "XWin Server" using the "Start" menu
nothing happens.  If I try either "startxwin" or "startx" or "xinit"
from the BASH shell I get:

giving up.
startxwin:  No such file or directory (errno 2):  unable to connect to X server
startxwin:  No such process (errno 3):  Server error.

Any suggestions?
