You want to access KDE software that is running on another computer.

<!--T:2-->
Reasons can be
* someone is running Linux and requesting support from you
* you want to train a user how to work with a specific gui software
* you have worked on your desktop computer and want to continue work in front of the TV (Simpsons coming) on your notebook

You will need the software '''x11vnc'''. For example, to install '''x11vnc''' on SUSE Linux, open a [[Konsole]] and type
{{Input|1=yast -i x11vnc}}

<!--T:4-->
So let's assume you want to access a KDE desktop session of ''user'' on the computer ''user-desktop''.
Open a [[Konsole|Konsole]] and do:
{{Input|1= you@your-computer $ ssh ''user''@''user-desktop''
user@user-desktop $ export DISPLAY=:0
user@user-desktop $ x11vnc}}

<!--T:5-->
The program x11vnc tells you where to connect. The line will read like
{{Output|1=The VNC desktop is:      user-desktop:0}}

<!--T:6-->
Connect from your notebook:
{{Input|1=you@your-computer $ vncviewer user-desktop:0}}

<!--T:7-->
The "user-desktop" term may be the host name of the server machine if that name is configured in the "hosts" file on the client machine.
