Because I couldn't find anything unusual or helpful in the logs I
captured packets using Wireshark. So far I found this:

-------- Solaris to Cygwin ------------------------
X11, Request, opcode: 52 (GetFontPath)

I can see the he gives this: tcp/Solaris_IP_address:7100

It looks like the Solaris sends font path, that Cygwin doesn't understand.
