Title:
  Xubuntu Xenial Beta 2 live image is not able to start

Status in ubiquity package in Ubuntu:
  New

Bug description:
  Downloaded Xenial Daily from 2016-03-22 on Windows, created a live USB
  using "Linux Live USB creator" and tested on an Inspiron 14 3000
  series laptop, system boots correctly, Xubuntu loading image (boot
  image) is displayed, but it seems to fail just before launching the
  ubiquity installer, because no language selector nor install/try
  Xubuntu options appear, instead, I get a window with following
  message:

  Sorry, Ubuntu 16.04 has experienced an internal error.
  If you notice further problems try restarting the computer.

  If clicking on the "Show details" button I get this information:

  I was unable to connect to the Internet so I couldn't send the report within the live USB environment, after trying and getting a connection error, a new window appears with this message:

  The installer encountered an unrecoverable error. A desktop session
  will now be run so that you may investigate the problem or try
  installing again.

  Clicking on the "OK" button on that window will bring a black window
  with some white text and then back to a "normal" live graphical
  session, with a link to "Install Xubuntu 16.04 LTS" on the desktop.

  I'll try to add more information as I can gather it.
