I have downloaded and installed Xming on my Windows 7 laptop. I am using a PUTTY session to connect to my linux box and start a X Windows application but the $DISPLAY variable is itself not getting setup properly:
I see the XMING icon on my system tray
X0.hosts file:
localhost
10.24.0.144
Putty->X11->Enable X11 Forwarding [X Display Location - :0.0]
But:
@10.24.0.144's password:

# echo $DISPLAY
#
As such I am not able to successfully start the X Windows app from Putty?
On the shell try : export DISPLAY="127.0.0.1:10.0" . Test with echo and then try X window application.
To permanently set it up, update the bashrc file.
