Remote display of a Linux desktop

For serving a display on Linux, such as when starting a Cygwin X session to your Linux server, you need to allow access to your machine. I did it like this on Fedora:

• Comment the line DisplayManager.requestPort in /etc/X11/xdm/xdm-config
• Uncomment the line #* #any host can get a login window in /etc/X11/xdm/Xaccess
• Comment no-listen = tcp in /etc/X11/fs/config
• Run /etc/init.d/xfs start
• In the [xdmcp] section of /etc/X11/gdm/gdm.conf, set Enable=true
• pkill -HUP gdm

  Cygwin startup

  Startup Cygwin/X like this (make sure there is no Cygwin X server running):

  XWin.exe -fp tcp/<servername>:7100 -query <servername>
  

  Alternatives

  You're probably better of running X over SSH (i.e. in Cygwin ssh -Y <server>) or installing VNC or some such application. But for this method, you do not need to install anything on the server. On a decent network, it is reasonably fast but you should not run it over the Internet, of course.
