Hi! After complete installation of cygwin/Xfree86 binaries, I tried to run startxwin.bat in win-explore, however, syntax error occurred by execution it. The message was as followed; USR/X11R6/BIN/XSET ROOT; unable to open display '127.0.0.1: 0.0'. Please let me know step by step solution. Thank you very much for your kind response in advance.
