I would appreciate it if someone could guide me as to what to be checking next. Let me elaborate. I have a desktop PC running Fedora 8 standard install but fully updated and a laptop running Windows XP. Putty works fine to get me a remote text connection. TightVnc works fine to get me a GUI connection to the primary display. Xming and Xlaunch give me a window on my XP machine that is solid grey noise with a black X mouse and then goes away or times out no error messages.
What steps should I take on which PC's to get a Window on my laptop which is a GUI control for my desktop Fedora machine. I thought Xming was the magic bullet, but no joy.
