"Cannot open display" or XDMCP problem ?

[Harold Hunt]

Ah, an easy question... I love these :)

You have to use the '-from %LOCAL_HOST_NAME%' option when using
Cygwin/XFree86 and xdmcp, where %LOCAL_HOST_NAME% is replaced with your
local host name.

Example:

start XWin -screen 0 640x480x16 -query foo.gazzy.com -from bar.gazzy.com

Eventually I'll add a section to the Cygwin/XFree86 User's Guide on this...
