What is "the console from the linux-server"?  I presume it's not what 
you see on the monitor attached to the Linux server at the time.  Is 
it the login window?

What is "the kde - view"?  I will presume it's something you see on 
the monitor attached to the Linux server.

I have never used VNC with Linux and KDE but your questions remind me 
of when I started using VNC with Solaris and CDE.

What do you mean by "don't know nothing"?.  Given your address in 
Salzburg, I can't be sure what you mean by this double negative.  You 
might be saying that you know nothing about Linux, or that you know 
something (not nothing) about it.

You will probably need to learn about Linux, or at least X11.  I am 
not giving you detailed information about that.

Then you will find that your server has several X11 displays.  One of 
them is associated with the computer's display hardware (video card, 
keyboard, mouse) which I will call the console.  The other displays 
(one or more depending on how your VNC server is configured) are 
nothing to do with the display hardware.  They are normally accessed 
using a VNC client only.

Using VNC with X (i.e. with Linux) differs from using it with Windows 
or the Mac in that the standard VNC server does not give you access 
to the console.  Instead it creates a virtual display which you can 
log in to and use independently of a user on the console.  You can 
have more than one of these virtual displays and have a different X11 
login session on each one.

If you want your Linux box to behave like a Windows one with Xvnc, 
where a user can connect using a VNC client and affect whatever the 
console is doing, then strictly you cannot do that.  You could 
develop a special hybrid of Xfree86 and Xvnc but as far as I know 
nobody has done that, and probably for good reason.

In practice you might be able to get close to what you want if that 
does not require strict duplication of the WinVNC behaviour.

One method would be to manually log in to the Linux box's console 
after booting, then connect to a local VNC server using the X VNC 
client in full-screen mode, and have people using the console use the 
VNC client only.  They would have to log in again on the client.  VNC 
clients elsewhere on the network can connect to the same server in 
shared mode and see whatever the console user sees.

This has many shortcomings. For instance, there is nothing to stop 
remote users connecting in non-shared mode and disconnecting the 
console user's client, in which case they'd be confronted with the 
login done manually after booting.
