You can't enable the Orca screen reader until after you click "Try Ubuntu" on Ubuntu bionic

[jokinglove]

When doing manual tests for Ubuntu Bionic. I am trying to enable screenreader after initially booting up ubuntu to its "Try" & "Install" Ubuntu options. When trying to enable screen reader (Alt+Super+S), nothing happens. Alt+Super+S only works after you click "Try Ubuntu".

I am running Ubuntu Bionic amd64 on Virtualbox

Status changed to 'Confirmed' because the bug affects multiple users.

Isn't the "Try Ubuntu" icon (and anything to click on at all) only after you've booted up in install mode?

Can you boot in "Try Ubuntu without installing" mode (from the grub menu) as a workaround?

This is caused by this commit:
https://github.com/GNOME/gnome-shell/commit/01d88119132f277196fa39c05b733dd1b4c5e951#diff-27bd3da1798473ae0fa876e6712c08a4

gdm: Remove separate greeter universal access icon

The idea behind always showing the icon on the login screen is that
the users' needs aren't known at that point. However we can achieve
the same behavior by including the 'always-show-universal-access-status'
key in GDM's presets, so drop the special-case.

I pushed a first branch that fixes the display of the a11y icon when the shortcut is pressed.
Now we still need to fix Orca startup.

This bug was fixed in the package ubiquity - 18.04.11

---------------
ubiquity (18.04.11) bionic; urgency=medium

  [ Sebastien Bacher]
  * Don't deactivate the screen-reader desktop keybinding, that was needed
    when ubiquity was handling the key press events but now gsd-media-keys is
    doing that. Listen to the corresponding key to start orca under
    ubiquity-dm since gnome-session isn't there to do it.
    (lp: #1741690)

  [ Iain Lane ]
  * misc.py: Fall back to SUDO_UID if PKEXEC_UID is not set.
  * ubiquity.desktop.in, misc.py: Pass through the ubuntu user's D-Bus session
    bus, if set, so that we can communicate with it.

  [ Jean-Baptiste Lallement ]
  * data/ubiquity.json: The separate greeter universal icon has been removed
    and the gnome-shell mode updated accordingly.
