Getting GDK_BACKEND does not match available display error in debian

Question

Actually, I am trying to run a mute browser on a remote debian server via selenium. I have firefox 46.0.1 installed on the server and I am using selenium version 2.53.1.

Whenever I tried to run a given test, I received the following error.

org.openqa.selenium.WebDriverException: Failed to connect to binary FirefoxBinary(/usr/bin/firefox) on port 7055; process output follows: 
Error: GDK_BACKEND does not match available displays

I have a firefox driver instance in my code:

saDriver = new FirefoxDriver();

can anyone help?
