i couldn't start an application which is installed on the Server with Graphic User Interface

[Philipp Hagemeister]

X applications (such as the ones rendering the graphical interface from
your Linux Server) need an X server they can talk to. The X server
renders the drawing commands by the application.

While Ubuntu includes an X server, Windows does not. You need to install
a Windows X server such as Xming (*and* enable X11 forwarding in your
ssh client).

Alternatively, you can use another protocol such as VNC or nomachine nx.
 You'll need a Windows client and a server on the .. well ... server. Be
warned that X tends not to perform well over high-latency low-bandwidth
links. Both VNC and nx are far more suitable on such

Additionally, the output
> Error in startup script: can't read "xcrys(platform)": no such
> variable while executing
> (...)
indicates an error in the application you're using (XCrySDen). Please
contact their support. Since you are apparently not running the latest
version, I'd encourage you to do so before reporting a bug.

Cheers,

Philipp
