Here are the three steps that I run VNC at my home.
1. Your Linux system might already have the software installed (type “which vncpasswd†to tell). If not, download the software from http://www.realvnc.com, and install it on your Linux and windows, respectively.
2. Launch from the server side (Linux)
$ vncpasswd
$ vncserver
3. Lanuch from the client (windows)
when prompted the server name, type linux_host_name:1, where linux_host_name is your linux box name and 1 is the port number for the vncserver, which could be a different port number sometime (you can tell it from the “vncserver†output at the previous step).
4. set kde
$ vi .vnc/xstartup
replace
twm &
with
startkde &
