Putty - Can't Open Display

Error: Can't open display:

If you are getting any error  while using the GUI - " Error: Can't open display" 



One of the reason is X11 forwarding is not enabled in your putty setup.

Solution:
Open Putty again -> Click on SSH -> X11 -> Tick mark "Enable X11 Forwarding" (as shown in fig)



Go back to your Session -> enter your "Host Name" -> Click on Open -> enter your username and password


and now test with "xclock" command -> this time you will get below screen (Note: Remember you should have already runing xming in the background).



Note: If you are getting below error -
"PuTTY X11 proxy: unable to connect to forwarded X server: Network error: Connection refused
Error: Can't open display: localhost:10.0"

Please start xming first and then enter "xclock" command.



I hope this will solve your problem.
