Seeing the Kubuntu GUI from a Windows PC

[Pete Holsberg]

I would like to be able to run an XDMCP connection from my Windows PC to 
my Kubuntu PC so I installed Xmanager on my WinPC.

Xbrowser does not see the linux box. "/*Note*: *Xbrowser* finds all 
Unix/Linux hosts on your local network automatically. If your Unix host 
is not found on the *Xbrowser* window, the host is not ready to serve 
XDMCP connections."/

Here is Xmanager's FAQ:

For XDMCP connection to Ubuntu
1. XDM Configuration
   1. Change runlevel to 5

   Open/etc/inittab and set the initial runlevel to 5 as following:
   id:5:initdefault:

   2. Enable XDMCP

     For GDM:
   
       Open /etc/X11/gdm/gdm.conf and set the Enable entry to 1 in the 
[xdmcp] section as following.
       [xdmcp]
       Enable=1
   
       Open /etc/X11/gdm/gdm.conf and set the DisallowTCP entry to false 
in the [security] section as following.
       [security]
       DisallowTCP=false

2. Firewall (TCP/UDP Ports) Configuration
    Open UDP port 177 from the PC to the remote host direction.
    Open incoming TCP ports 6000~6010 from the remote host to your PC.

3. Reboot the remote host and start Xmanager
    # init 3; init 5

Question 1: since Kubuntu 6.10 doe snot have /etc/inittab, exactly where 
do I go to change the runlevel to 5?

Question 2: since I am not running GDM, what do I do to enable XDMCP?

Thanks.
