title: Run gnome-terminal from tty
body: <p>How can I run <code>gnome-terminal</code> from <code>tty1</code>?</p>
  
  <p>I tried setting <code>$DISPLAY</code> variable to <code>:0</code>, but still nothing and <code>gnome-terminal</code> doesn't appear in the X window system.</p>
  
  <p>However, <code>xterm</code> and <code>firefox</code>, work fine from tty1.</p>
  
  <p>What am I missing?</p>
