I can think of 2 possible issues/solutions: With XDMCP under VcXsrv or Cygwin XWin, you often need to use this argument to, usually when you have multiple (virtual) network adapters: -from 192.168.0.20 XDMCP involves a forward-confirmed reverse DNS lookup. So if you have incorrect DNS records like the following: PTR: 192.168.0.20 -> windows-pc A: windows-pc -> 192.168.178.20 Then this problem will happen. -Mike -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://x.cygwin.com/docs/ FAQ: http://x.cygwin.com/docs/faq/
