title: GDM display manager fails to display login
body: <p>So I've got an interesting one here...</p>
  
  <p>When I boot my computer I'm presented with a blank screen after the Ubuntu loading screen. The weird thing is that if I go into the grub loader, then select recovery mode but select to continue with normal boot it works fine.</p>
  
  <p>I tried reconfiguring as well as reinstalling GDM. I'm sort of at a loss of ideas now. Any and all help is definitely appreciated. Thanks!</p>
