Desktop Environments

• The GNOME Project: Accessibility (GNOME Developer Documentation). See also the Introduction to Assistive Technologies.

• MATE Desktop Environment. MATE is a fork of the now unmaintained GNOME 2. When the GNOME Project released GNOME 3, much of the accessibility work had to be redone. For this reason, many people with disabilities continued using GNOME 2 and, more recently, MATE. Some consider MATE the best choice for users with serious visual impairments (including blindness). (However, GNOME 3 has a better magnifier and a black-on-white contrast theme.)
  In 2014, Linux Mint included MATE as one of its default desktop environments. Fedora also has a MATE Compiz spin. Other distributions that offer a Mate desktop are PCLinuxOS (which aims to ease the transition from Microsoft Windows to Linux), Ubuntu Mate, Arch Linux (see its wikipage about desktop environments), Debian (you need to select the desktop you want during the installation process), Mageia (you need to select Mate during the installation process), Gentoo (see the Gentoo page about Mate) and OpenSUSE (see the release notes). For a lightweight Linux distribution that offers MATE, see Alpine Linux (installation instructions for MATE).

Accessibility in General-Purpose Distributions

• Prater, Devin: Linux Accessibility: an unmaintained Mess, Devin Prater, 08.05.2022.
  A blind computer users describes his experience with the Linux desktop. In the early days of the Linux desktop, there were distributions specifically for people with disabilities, namely Vinux and Sonar. After these disappeared, people had to rely on the accessibility features in mainstream distributions.
  Gnome 2 was the most accessible desktop Linux ever had. In Gnome 3, accessibility had to be redone because it was a completely new desktop, but no one was paid to do it. In Gnome 4, accessibility is not what is should be either. On the KDE desktop, progress is also very slow. Work is being done, but as is everything in the world of access technology, it’s very slow. Things happen practically only when a new sighted person is inspired to help, until they get burnt out by the lack of help from the open source community and lack of interest from the wider blind community. Mate, which is a continuation of Gnome 2, is also sliding backwards with regard to accessibility.
  The author also describes the challenge of installing Fedora (with the Mate desktop). Fedora has accessibility support turned off by default, whereas Debian has it turned on. However, accessibility for Chromium and Chromium-based applications needs to be turned on separately. And Chromium browser still become unusable after a few pages.

Specialised Linux Distributions

• Accessible-Coconut is a Linux distribution based on Ubuntu-Mate that claims to be completely accessible for persons with visual impairment.
  Accessible-Coconut provides some accessibility information in the form of a feature list on SourceForge. The listed features include an installation process is fully accessible to a visually challenged user, the console screenreader Fenrir, support for Braille input, accessible Chrome and Firefox, a Daisy player, accessible audio and video editing solutions. However, it does not say anything about the screenreader Orca, zoom functions, high-contrast themes or features to make the cursor more visible.
  See the Accessible-Coconut Google Group.
  See also Accessible-Coconut - The Linux Distro For Blind and Visually Impaired Users (OldTechBloke on YouTube, 35 minutes, 10.04.2021). Note that the creator of this video is not an accessibility expert and points out that his video is not a review but is more about raising awareness.
• ADRIANE - Audio Desktop Reference Implementation and Networking Environment: ADRIANE is an easy-to-use, talking desktop system with optional support for braille, which can be used entirely without vision oriented output devices.
• Vinux: Vinux is or was a Linux distribution based on Ubuntu that is optimised for the needs of blind and partially sighted users.
  Note: It is possible that Sonar and Vinux will merge and use Fedora as their starting point; that was the outcome of a meeting in early 2017. See also vinuxproject on SourceForge and Vinux: A special operating system for the blind/visually impaired (Technology for Blind on YouTube, 41 minutes, 29.07.2019).
  According to DistroWatch, Vinux is a dormant project (last verified on 09.11.2021).
• TalkingArch: a respin of the Arch Linux live iso modified to include speech and braille output for blind and visually impaired users.
  TalkingArch is (or was) a bootable CD or USB image optimised for blind users. The system started speaking at boot time. The latest release dates from October 2017. TalkingArch is not an official release of the Arch Linux project. See also The TalkingArch Blog and the TalkingArch wiki page. According to the Arch wiki, TalkingArch was discontinued in 2017 and was succeeded by Tarch, the new talking arch livecd project.
• Tarch describes itself as the new talking arch livecd project. Its latest version is Tarch 2020.02.24, released in February 2020.
• HandyLinux was a Debian-based French distribution aimed at beginners, elderly people and anyone who needs simplicity. Version 2, which was released on 16 May 2015, was based on Debian 8, although it was only available as a 32-bit version. It used Xfce as desktop environment and included the Orca screen reader (which is part of GNOMEShell), a screen magnifier, an on-screen keyboard and simplified menus.
  In July 2016, HandyLinux joined or became Debian Facile.
  As of November 2021, the website handylinux.org cannot be reached.

• Fourdan, Oliver: Accessibility Features for Mutter/GNOME Shell on Wayland (GUADEC on YouTube, 21 minutes, 31.08.2019; Creative Commons Attribution licence).
  

  Historically, accessibility features in GNOME on X11 were handled by different components such as Xorg itself for keyboard accessibility, “mousetweaks” for mouse accessibility, GNOME settings daemon for locate pointer, AT-SPI registry daemon, etc.

  All these features relied on the ability to query the input devices on behalf of other clients or generate fake input events, neither of which is possible with Wayland anymore.

  The purpose of this talk is to present the current status and the technical solutions chosen in mutter/gnome-shell to make these features available on both X11 and Wayland.

• Introduction to Orca Screen reader for Linux (ZAccess on YouTube, 17 minutes, 26.11.2021).
  The introduction to this video claims that Gnome is the most accessible, if not the only accessible graphical user interface in Linux. When asked whether this is really true, the video's author responded, I do stand by that statement. While there are other desktops that are better for specific users with specific disabilities (Emacspeak comes to mind here and will be the topic of a future video and I remember hearing some good things about XFCE's high contrast mode), I believe that Gnome is generally the most accessible desktop in terms of available assistive technology options (including a High Contrast mode under accessibility settings. Many desktops don't even have that accessibility settings icon in the first place. Many desktop developers also haven't included the underlying accessibility architecture necessary to run things like screen-readers and speech-to-text software in the first place. If you're thinking of a specific desktop that has better accessibility features than Gnome, including underlying accessibility hooks for screen-readers and speech-to-text software, do let me know and I'll check it out.
