[Bug 1231091] Re: Screenreader starts, but does not work with installer (ubiquity) in live session

[Sai Vinoba]

@hellsworth, nice catch. That could be an issue.

As you noticed, bug #1874283 is duplicate of this. I'll try to combine
the two with current status, to best of my understanding and testing.

1) When we hear the sound, we can start orca screen reader with Super+Alt+s. No audio feedback for the screen, language selection or choosing one of 'Try Ubuntu (MATE)' or 'Install Ubuntu (MATE)'. 
 - Current status: Audio feedback available in Ubuntu default but not in Ubuntu MATE.

2) Some commented that if they boot into efi mode the screen reader installer worked fine but had problem only in BIOS mode. 
 - Current status: Both modes have problems (definitely 20.10 onwards).

3) Some commented that if they used live mode (Try Ubuntu), the screenreader worked fine for installation but not if they choose installer directly (Install Ubuntu). 
 - Current status: Screen reader does not work if installer started from inside live mode both in Ubuntu default and Ubuntu MATE.

4) On the other hand, we were suggested quite the opposite; that it will work fine if we select installer directly but not if we select live mode first. 
 - Current status: Screenreader works when starting installer directly only for Ubuntu default. No luck on Ubuntu MATE.

5) Screen reader works if we start assistive technology in live mode (Thanks @artemiy-22). 
 - Current status: This works in Ubuntu MATE (could not get it to work on Ubuntu 20.04). 

Following are steps to make screenreader install work in Ubuntu MATE.
  a) Select 'Try Ubuntu'
  b) Once the desktop loads, open 'Assistive Technologies Preferences' and check 'enable assistive technologies'. This I had to do even when screenreader was on (Alt+Super+s).
  c) Choose 'Close and Log Out'. (Just using 'Close' does not work, we have to end the current session).
  d) Select 'Live session user' in the login screen and hit return (no password).
  e) After we re-login and start the screenreader, we can use installer in blind user mode.

Title:
  Screenreader starts, but does not work with installer (ubiquity) in
  live session

Status in ubiquity package in Ubuntu:
  Triaged

Bug description:
  Image: 20130925

  I started the image and let it boot to the gui selector for live
  session or install only. When the drum sound played, I pressed ctrl-s
  to start the screen reader and heard the familiar "screenreader on"
  sound, and it read the options to me.  From there, I started the live
  session, and went into the installer, but orca would not read any of
  the screens.  I also started a terminal window and noticed that it
  says "window" when I move the mouse over the unity launcher icon, and
  "unity dash" when I click on it, but nothing in the terminal is read
  to me either.  So I don't think this is limited to just ubiquity.
