title: X11 unable to maximize applications when no window manager is used
body: <p>We have a Linux based system that does not use a Window manager.  When we start certain applications (for instance Firefox) from a terminal window (e.g. Firefox &amp;) we find that no matter what we do, we can't get the application to display full screen.</p>
  
  <p>If we run xrandr, it shows the default resolution is 1280x1024, but when we try to maximize Firefox (by pressing F11) the application is only sized to 1203x650. </p>
  
  <p>Another application that seems to have the same problem is the evince PDF reader.</p>
  
  <p>Our application is not configured to run a window manager (and we don't want to add one), so I'm wondering if there is something else that we can do to get these applications to render full screen.</p>
  
  <p>Thanks...</p>
