title: i3 window manager: black screen, no mouse
body: <p>I installed i3-gaps on my arch running with a nvidia card. A gnome-session works fine using the nvidia.</p>
  
  <p>After the installation i added to the xinitrc file:</p>
  
  <pre><code>exec i3
  </code></pre>
  
  <p>however when I execute <code>startx</code> in a tty, the X Server starts successfully, but i3 shows nothing else but black screen (no shortcuts are working)</p>
