I am trying to get XDMCP working over SSH on CentOS 4.4 from a windoze box running Cygwin/Putty I have set Enable=true in /etc/X11/gdm/gdm.conf restarted the X server, logged in with Putty and X11 forwarding enabled. I then try to start the Xserver with the following commands # gdmXnestchooser localhost or # Xnest :1 -query localhost Both commands will successfully display a X window and show the X mouse pointer but not the chooser. Can anyone tell me what I am doing wrong? Thanks Dean
