Error: Unable to initialize gtk, is DISPLAY set properly?

Question

I'm trying to run Image application from server "bert"

I connected through my OSX Maverick as

ssh ak324@bert.eecs.qmul.ac.uk

I compiled my file with

$ make

but when I run the resulting file

$ ./window

it gives me the following error:

Error: Unable to initialize gtk, is DISPLAY set properly?

How can I solve this problem?

You should connect with the -X or -Y option to be able to launch graphical applications:

ssh -X ak324@bert.eecs.qmul.ac.uk

If that doesn't help, you should consult /etc/ssh/sshd_config whether X11Forwarding is enabled.

Do you know how to do this in Putty? – CodyBugstein Aug 08 '14 at 13:09
Just check "Enable X11 Forwarding" in Putty under Connection / SSH / X11. – Endre Aug 09 '14 at 15:04

Did it, and still getting `Error: Unable to initialize gtk, is DISPLAY set properly?` – CodyBugstein Aug 10 '14 at 12:19

Then you can connect with

ssh -Y ak324@bert.eecs.qmul.ac.uk

Try running ssh with the flags -Y -v.

If the following line appears on the terminal during the ssh connection, install xauth on your remote system.

debug1: Remote: No xauth program; cannot forward with spoofing.

As suggested here.
