I am a totally blind user, and use both a screen reader and a braille display to interact with kali which is installed on my home computer but I want to take a live image withme but have these accessibility features available on boot.

Currently, we do not have an entry in the live iso that enables the accessibility features on the boot entry. If you enable them, they will not persist unless you have set up persistence, and boot using that option. I appreciate you opening the issue, and we will look into what we can do for this over here.

This report has been filed against an old version of Kali. We will be closing this ticket due to inactivity.

Please could you see if you are able to replicate this issue with the latest version of Kali Linux (https://www.kali.org/get-kali/)?

If you are still facing the same problem, feel free to re-open the ticket. If you choose to do this, could you provide more information to the issue you are facing, and also give information about your setup?
