[putty] problem with X windows

[blacksmith11]

hi everyone! i'm new and i hope i'm in the correct section.
i started using linux 3 months ago, so i'm noob at all i use linux through putty. indeed i use it to connect to university server from my home pc (windows).
i have no problem with the connection and i can simply use programs like pico o g++ that don't have any external windows... however i have problem with programs like gnuplot or gedit that need a external window to run correctly. when i run them i get this problem:

The application 'gedit' lost its connection to the display localhost:11.0;
most likely the X server was shut down or you killed/destroyed
the application.

or when i simply use the comand display i get:

X connection to localhost:11.0 broken (explicit kill or server shutdown).

surfing the net i found some hits and i enabled x11 fowarding that before wasn't enabled and indeed this comand didn't work at all...
can someone help me?
sorry for the bad english and for the maybe not precise language :P
thanks

I dont know about gnuplot but gedit is a graphical GUI program and you are trying to access it through a command line interface. Of course it is not going to work.
