For use with Cygwin, I had to set up a font server on an HP machine, so that I could use the native HP fonts in a remote display session for displaying an in-house developed application.
These are the steps you need to take.
Edit /etc/services to allow font serving over the network; add this line:
xfs 7000/tcp # X font server
Note that this is different than the default port on Linux systems, 7100.
Start the X font server:
Check with ps that it is running.
Start the Cygwin X server with the following options:
XWin.exe -depth 8 -fullscreen -fp tcp/<servername>:7000 -query <servername>
I needed to start it in 8-bit colours because the application is really old and people using it want to have the same colours as ever. When running in normal 24- or 32-bit mode, colours were mapped in several nice but wrong ways.
