[Bug 772535] Re: Keyboard layout chooser freezes during ubuntu installation

Same issue in 13.04 on an Acer laptop
First time I think it was resizing partitions in the background.  I thought it was just slow and tried with the keyboard and mouse to change the keyboard.  It stalled and despite being left for eight hours did not come right.  I could go to the menus in the top right hand corner but always came back to the stalled keyboard selection.
After reboot I chose the option to start from scratch with the Ubuntu install and just accepted the keyboard default and it went through normally.

Title:
  Keyboard layout chooser freezes during ubuntu installation

Status in “ubiquity” package in Ubuntu:
  Confirmed

Bug description:
  Binary package hint: ubiquity

  This bug exists on Ubuntu 11.04 Desktop Edition but I've  experienced
  this bug on previous versions too. I can't remember which exactly
  though.

  Sometimes, while selecting different countries in the left list, the
  layouts in the right list freeze in one of the countries selected.
  After this happens, selecting a different country will not refresh the
  layouts list and it's impossible to complete the installation as
  clicking on either "Back" or "Forward" won't work.

  I couldn't find any way to continue with the installation besides
  rebooting the system and restarting the installation process.

  I'm not sure about the combination of factors that lead to this bug
  but I believe that one of them is how fast you switch between
  countries. I think that the background installation process may have
  something to do with it too.

  1) The quickest way to reproduce this problem is to press the cursor
  up key repeatedly and quickly while the focus is on a country. At one
  point the layout list on the right will cease to update.

  2) This happened to me more frequently when going through the list
  with the cursor keys but I was also able to reproduce it using only
  the mouse.

  3) If I wait for the layout list on the right to load before selecting
  a new country, then I can't reproduce the problem, so switching while
  the list is loading seems to be part of the problem.

  This happens to me a lot on new installations because, to get to
  Portugal faster, I press "p", "o" (which selects Poland) and down
  cursor key to select Portugal. If I do this too quickly, chances are I
  have to restart the installation process.
