** Description changed:

+ ### Updated bug description
+ 
+ Testing the 16.04.1 release candidates I've encountered the above with
+ both Intel ® GMA4500 and nVidia GeForce 7025 / nForce 630a graphics
+ chips when booting from the standard boot menu. If the iso boots to the
+ login screen I can simply click on Live Session User w/o entering any
+ password and get to a functional live DE.
+ 
+ I've also encountered installer "crashes" where the installer seemingly
+ just dies (maybe when the screensaver activates) and after rolling up
+ the blinds I find that I've landed back at the login screen. In this
+ case the simple workaround is to start the installation from the
+ advanced boot menu.
+ 
+ Selecting either Try Ubuntu GNOME without changes or Install from the
+ advanced boot menu works perfectly fine without the need to edit or add
+ any boot parameter.
+ 
+ This does not affect Ubuntu, so it seems to be Ubuntu GNOME specific.
+ 
+ ### Original bug description
+ 
  Testing Ubuntu GNOME Xenial 20160222.1 amd64 and I find that selecting
  Try Ubuntu GNOME from the standard boot menu displays TTY 1 and requests
  a username but the keyboard appears to enter no text. It will however
  eventually boot to the login screen. After several tries I find the
  following steps reproduce the behavior:
  
  (1) Boot Ubuntu GNOME Xenial live image, wait for the standard boot menu to 
appear, and select Try Ubuntu GNOME.
  (2) You'll find that the screen displays TTY1 + requesting a user name.
  (3) Do nothing and wait 2 to 3 minutes after which a GUI login screen appears.
  (4) Click on Live session user and a new screen appears requesting a password.
  (5) Enter nothing and press Enter and you'll finally get to the live desktop.
  
  I was going to upload some pics of what happens but I'm unable to mount
  my camera in the live session.
