@jab01701mid @aral The problem isn't a lack of a screen reader, it's the lack of a consistent user-interface API. Linux has two major UI frameworks (GTK+ and Qt) and a whole mess of minor ones, so there's no single point you can plug in to and start describing what's on the screen.
@carnildo @aral True, the fact that Windows (and MacOS ?) supports only one Windowing system might seem like a "feature".
But assuming people are willing to use GNOME/GTK, or even Wayland, on Ubuntu, it seems like there is a good chance this could be available for linux soon, which despite the complaints, offers some significant advantages compared with Windows platforms, for all users.
