3. Orca Screen Reader
3.1. Default Orca start
3.2. Keep Orca configured

1. Introduction


The opt.sqfs with Xorg, Gnome and so on, has the programs brltty and the screen reader Orca included. To automatically start brltty and Orca you have to uncomment the last line in the file "ploplinux/bin/rc.local". There is the command "#sh startbrl". Remove the "#" at the beginning of the line. The Plop Linux ISO file ploplinux-4.2.2-X-brl.iso is already configured to run startbrl during the boot process.


2. The startbrl script


You find the script in the ploplinux/bin/ directory. When Plop Linux is booted then the directory is /media/ploplinux/bin/.

The script starts the program brltty and creates a script that Orca automatically starts when Gnome is started. In the second line from the bottom of startbrl you will find the autostartx command. autostartx automatically starts Gnome when Plop Linux has been booted.

When startbrl finished executing, then you hear a beep sound. If you don't auto start Gnome, then you are at the command line when you hear the beep.


3. Orca Screen Reader


3.1. Default Orca start


Orca is not configured. When Gnome has been started, then you can do the initial Orca setup. The setup program is started automatically and opens the Orca Preferences Panel.

When you want to kill Gnome then press the keys CTRL ALT BACKSPACE at the same time. This will stop the X Server (and Gnome) and you are at the command line. To start Gnome again you have to run "startx".


3.2. Keep Orca configured


When you configured Orca (and other stuff) and you want to automatically restore these settings when you boot, then you have to save the settings with the following command:

tar cfz /root.tar.gz /root

When you booted from a writeable drive (USB drive, network share, ...) then copy the file /root.tar.gz to the /media/ploplinux/opt/ directory. startbrl will extract this file during the boot and all your settings will be restored.

When you booted from a write protected drive (DVD and so on) then you have save the file /root.tar.gz to a writeable drive. Later you have to create for example a new ISO with the root.tar.gz file in the ploplinux/opt/ directory.
