I am (again) experiencing some issues when running Cygwin/X in

works as expected. But when I try to connect to my remote Linux system
with the command 'xwin -query 192.168.0.21' (or with the 'XLaunch'
program and choose XDMCP) the screen stays black. Things used to work,
but apparently something broke my setup.
Im running the latest Cygwin/X, and applied all current updates on my
Fedora 21 Linux system. Im running KDM.
Any and all ideas are more than welcome, as I have no idea whats going
on here.

Assuming your wireshark filter includes X11, you should be seeing a X11
connection request from 192.168.0.21 to the X server here.
Since the same X server version was working for you before (to a
different IP address), I can only suggest you examine what else has changed.
You might want to check your firewall/network configuration.
