I've temporarily set up another instance (no X) at u:\cygwin64. I notice that if I start up the X server on the first instance, X programs started under the second instance cannot connect to the XServer. They always get, for example: jim AT HOME10 ~ $ xclock Error: Can't open display: :0 But this works just fine if I run the same command in a mintty window launched under the first instance. This happens even with "Disable access control" set, and also "xhost +". I also tried DISPLAY=localhost:0 but that doesn't work because the X Server isn't listening on port 6000. Is this an artifact of how Cygwin/X emulates unix sockets? What option do I need to change to have the XServer listen on port 6000?
