Add an option to automatically configure Orca screen reader to start with lightdm and lightdm-gtk-greeter
In order to get the Orca screen reader to start and read the login window for lightdm when installing the Mate desktop, it is necessary to manually modify /etc/lightdm/lightdm-gtk-greeter.conf and add the following lines to the bottom of the file.
[greeter] reader = orca --replace a11y-states = +reader
Please add an option in the archinstall script that will automatically do this. This means a blind user would only need to select this option and make sure Orca was installed by typing it into the additional packages to install prompt. This would save a little time as the installation and necessary configuration would be completely automated after the appropriate parameters are specified.
We automatically enable these things if we detect that the ISO has for instance espeakup enabled. Perhaps we can do the same for mate desktop?
