An Accessible Ubuntu Server installation via Braille Display
Hi everyone, Pawel Loba reports that he was able to sucessfully install Ubuntu Server 12.04 by starting the installation manually, passing parameters to enable braille support at the boot prompt. I've compiled the steps Pawel used along with the steps Bill Taylor provided to get speakup running on the installed system as a "HowTo" guide. I hope this information is helpful to others. Thank you Bill and Pawel for your contribution:) Jeff Pawel reported that during the installation of Ubuntu Server 12.04 his braille display began behaving erraticly. The solution to that is to exit the gui menu and start the installer manually, passing the appropriate parameters at the command prompt. To manually start the installation of Ubuntu server 12.04 perform the following steps: 1) boot to the Ubutnu Server 12.04 installation CD; 2) After CD stopped spinning, exit the gui menu by pressing the escape key twice and enter key to confirm that you want to perform a manual install; 3) At the boot prompt type: install text brltty=auto and press enter; (this will start a manual install with braille support) The rest of the installation is displayed on your unit, just follow the typical installation screens. Unfortunately after restarting the system there is no Braille support. you will need to install brltty sudo apt-get -y install brltty and press enter. type your password hit enter and waited till your hd goes silent. start brltty: brltty -b auto -d usb: Install alsa sudo apt-get install alsa-utils run < alsamixer > #to un-mute sliders oo below sliders , and 50 or more on slide Install espeakup: sudo apt-get install espeakup -y > Start speakup: modprobe speakup_soft start=1 sh /etc/init.d/espeakup start manually edit /etc/modules to add the line: speakup_soft start=1 to ensure speakup starts after shutdown / restarts. -- Ubuntu-accessibility mailing list Ubuntu-accessibility@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-accessibility
Main menues and indicator main categories doesn't presenting with the braille display in Unity 2d
Hy, Yesterday Joanie fixed with an Orca braille module bug with Indicator main categories related: https://bugzilla.gnome.org/show_bug.cgi?id=673648 The problem is following: Orca sending right the selected main indicator categories with the braille display, but after the right text presenting I see my braille display in Unity 2d with following text: "Unity-panel-service application window" The problem unfortunately I think not indicators specific, I reproduced this issue with any applications. An example reproducation steps if you using braille display: 1. Launch Terminal. 2. Press F10 key. Orca right presenting braille the first selected menu item in file menu. 3. Press right arrow. Orca want presenting the new selected Edit main menu, but Unity send the quoted text. For example, the speech output is following when I pressed right arrow in Terminal: "Edit label Window" I have equals experiences under Gedit application. Why not menu the edit menu role type? Why label? When I experienced this issue, I used Unity 2d and I using Orca latest master version. Already reported this issue? If not, enough to report Launchpad this problem in Unity package and paste this letter, or need some extra informations if I would like doing absolute correct report?

Dispaly auto-detection is only possible for USB Braille displays, and even then, one of these displays had to be disabled for detection, due to it conflicting with other devices users used for serial devices, since the display and these serial devices used the same chip. Looking at the file that is responsible for the detection, /etc/udev/rules.d/85-brltty.rules, it appears that one of the HandyTech displays was the problem, which display it is exactly, I am not sure. For serial/bluetooth displays, unfortunately at the moment manual configuration is required, since it is not easily possible to detect these displays. There is a mechanism in place to configure these displays when one chooses to use Braille from the live CD accessibility menu, however this is not yet speech enabled, something which I hope to address in the release of Ubuntu after intrepid. If something else is broken, I would appreciate bug reports, and the steps you have taken to reproduce the problem. Unfortunately I do not have a USB Braille display, so cannot test and check detection myself. I hope this clears things up, and please feel free to contact me should you have any further questions.

why Your development team disabled automatic braille display detection and support during booting from A Ubuntu live CD?
Good afternoon, I Am very sad and unhappy, that Your accessibility development team considered to remove automatic braille display autodetection and support during booting from A live CD. I found out, that Your development team probably made this decision while officially publishing Ubuntu Hardy Heron Live and later even official CD. I would like to please You, if You could give Me atleast a short programmers explanation, why did You have to make this change to ubuntu distribution. I very liked automatic braille display detection algorithms and I have never problems, that Brltty displayed message during booting up, that screen is not in A text mode. Because after starting Gnome, I could start Orca Screen Reader and I could enable braille support. Using command line parameters is not comfortable during booting process. And I AM not sure, if this would work reliably. Thank You very much for Your answer. The kindness regards.

Error with braille display
Hi, I have an HP pavillion laptop and a focus 40 braille display (usb interface). I have ubuntu 7.04. When I boot this ubuntu version from the cd or from the hard drive where it is installed, I think brltty sstarts up with ubuntu and I don't need to do nothing. What happens is the following: In the normal cenarius, brltty presents the message brltty 3.7.2 then presents screen not in text mode because ubuntu starts with the graphical interface.. Then when orca starts, the braille display works too. Sometimes, instead of presenting screen not in text mode it presents 1 startup error and I cannot put orca working with the display. When in this situation, I typed dmesg > filename.txt and the content from the beginning is: [ 738.22] usb 3-1: usbfs: process 3349 (brltty) did not claim interface 0 before use [ 738.26] usb 3-1: usbfs: process 3349 (brltty) did not claim interface 0 before use [ 738.30] usb 3-1: usbfs: process 3349 (brltty) did not claim interface 0 before use [ 738.34] usb 3-1: usbfs: process 3349 (brltty) did not claim interface 0 before use [ 738.38] usb 3-1: usbfs: process 3349 (brltty) did not claim interface 0 before use ... (it's the same thing till the end) Although in this situation it doesn't work with orca, it works with the textual consoles. What's the meaning of this? And what can I do to solve this? I don't have experience. Thanks for the attention Best regards Sérgio Neves-- Ubuntu-accessibility mailing list Ubuntu-accessibility@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-accessibility
testing braille display
Hello all, I tested setup of my display compatible with ALVA with negative result. It works from console by runing this command: sudo brltty -b al -d /dev/ttyUSB0 I tested the brltty-setup (F5, 4, enter, enter)with lines: u 0 al Display was not started.

Partly because we've not had good access to braille displays. For Edgy we will focus on the graphical install path with Orca and Ubiquity (the graphical installer) and hope to have some basic braille support via that route. BRLTTY is a bit complicated because some devices need special configuration. I'm already in communication with the BRLTTY maintainer and we will work at making BRLTTY-based installation smooth for Edgy+1. The thing to realise about Edgy now is that we are already past 'Feature Freeze', which means I have to submit a well-founded application to the release managers ever for relatively small changes. So changes to the text-based installer are completely out of the question at this point. It is however a good time to start planning features for Edgy+1 so that we can get some good-quality specs in place for the development summit in November. For one thing we need to think about how to best configure a wide range of braille displays in a Live CD environment. As many as possible should be auto-detected and there should be a reasonably simple way of configuring the rest.

Edgy Eft installable with Braille display?
Hi, Can the version Edgy Eft that is forthcoming in October be installed via BRLTTY? On <http://www.ubuntuforums.org/showthread.php?t=246334>, Henrik describes the installation with a graphic installer. I am wondering whether there will be an installation based on text with a Braille display as well. This would be highly suggestive especially for the server version and will probably be feasible as IMHO Ubuntu is based on the Debian installer. The actual installation of the Debian installer works really well. At the moment, BRLTTY is not being installed here, which hopefully will be corrected soon. Thanks in advance for your answers.

It is indeed planned, and much more besides. I am in the process of writing up a few specifications for things I would like to see added to the next release. Wwhile this doesn't deserve a specification on its own, I think we could do with a spec that addresses a few asthetic considerations, just so we don't forget to do them. What do others think?

Autodetecting the braille display with BRLTTY
Hi to all I recently checked the Dapper Drake live CD and I found a good job done in accessibility support, congratulations to all. I would like to make a suggestion for the next release would be possible to add braille-driver autodetection for the next live CD? I have set it in my brltty.conf braille-driver auto and it works fine When I plug differents braille displays in my laptop at home or at work. And the user has no to worry about what model of braille display is using and would get braille support at boot, so Gnopernicus or orca can use it.
