As far as I know you designate one of them to be the "core pointer".
That's the one that will control the mouse pointer. Programs that need to
(say, CAD programs) can ask to be notified about the other mouse's
position through the X Input Extension.
The two monitors will conceptually be one big screen. You use the
serverlayout section in the configuration file to tell the server which
one is the left screen and which one is the right one (or top/bottom).
If the resolutions of the two monitors don't quite match, i.e. if the
combined area is not a rectangle, you will get "dead areas" which
conceptually exist but don't have any actual monitor pixels to go with
them.
If the window manager you use is new enough to know about the dead areas
and not put any windows there, this won't be a problem. Since you are
probably running a newish KDE I wouldn't worry about it. Still, should
it turn out to be problematic you can fix it be upgrading. [just a guess:
since you are both German and running KDE, are you using SuSE?]
The one mouse pointer can be moved from screen to screen with the
"core pointer".
You can use an option in the configuration file called "SendCoreEvents"
which makes the second mouse generate "core events", too, meaning it will
also control the mouse pointer.
Use "man XF86Config" for the details of setting this up.
Here's a tasty quote to whet your appetite:
[...]
Here is an example of a ServerLayout section for a dual
headed configuration with two mice:
Section "ServerLayout"
Identifier "Layout 1"
Screen "MGA 1"
Screen "MGA 2" RightOf "MGA 1"
InputDevice "Keyboard 1" "CoreKeyboard"
InputDevice "Mouse 1" "CorePointer"
InputDevice "Mouse 2" "SendCoreEvents"
Option "BlankTime" "5"
EndSection
[...]
