Re: [orca-list] Problem running orca

[Speedy <speedychair live com>]

My understanding is that Python 2.7  can be used with up to orca 3.5.9.  Above that you will need Python 3 and everything associated with Python 3.  I think this requires upgrading all gnome applications as well to 3.6.  Python 2.7 does not need to be removed.  The two versions will coexist.

Do you still only have Python 2.7 installed?  I have no direct

Python 3 was orca 3.5.9.  This would mean that either you need to
downgrade to orca 3.5.9 or install python 3. 

ah. Yes I have only python 2.7 installed. Do you know how I could check that's
not supported anymore? Do you mean that now orca only works with python3? Are
they important evolutions between 3.5 and 3.7.1, or they are progress out of
user eyes?

Thanks for your answer.

Hi,

I try investigating on my problem, and as I don't find anything, I tried
analyzing the error on a semantic point of view. Note I upgraded orca

to 3.7.1.

If I understand:
Could not locate wnck_screen_get_default: (null)

Indeed, wnck_screen_get_default is designed to contain a real window

manager.

null isn't correct. Does it mean orca depends on the desktop manager? What
should this function contain or render? I read "WMEH spec". But what

desktops

have this spec and is it mandatory?

What could send or receive this function to read windows such as OOo or

firefox?

Can I rename openbox in null or change anything to lead orca to work,

ia*a run,

open its setting' window and read apps it's able to read (i.e. not

xterm, but

at least other gtk apps). Yes, I want to disassemble orca and the desktop
manager. Isn't possible?

Finally, what kind of desktop manager /ould be accepted, without

installing all

a DE such as xfce or gnome?

Thanks for your info.

JP

Hi,

So I tried exporting both variables. I remember now that I used them

too on

Debian. Unfortunately, I still have the same behavior: the error I

mentioned

and orca freezing. I get:
gi._glib.GError: Could not locate wnck_screen_get_default: (null)

I did:
export GTK_MODULES=gail:atk-bridge
export SAL_USE_VCLPLUGIN="gtk"
startx

But as you mention I'm sure orca can work without DE (I hope). I don't

expect to

access to xterm, but rather to see "Xterm Inaccessible" and alt-tab,

read the

orca /indow, or firefox, or OOo.

Thanks for your help.

Best regards,

JPM

Try those commands.

Hi,

To help me understanding how things woro together: do you mean
that, if the window manager and the terminal are not supported, we
cannot read also apps which are launched from them? To read firefox
or OOo, I absolutely have to run orca in a supported environment
(gnome, lxde)?

That's right one of my 1st experience was to see if I could use
orca to read firefox and OOo without installing gnome3 or a
desktop, but only with a window manager. Is it impossible? Can't
orca be distinguished at all of the desktop infrastructure? I
thought I could do this as on a Debian, I could run only some
components of gnome and orca (terminal and mutter) then orca read
firefox.

Merci beaucoup pour votre aide,

Regards,

JPM

All the other suggestions and questions notwithstanding, I wonder
if anyone's tackled the most fundamental problem:

Orca does not read Xterm.  It never has in my experience neither
with braille nor with speech.  Gnome-termilnal yes, xterm?  Ce
n'est pas posible, mon ami.

Also, OpenBox is something I thought was not accessible.  If you
require minimal resources, perhaps you should try getting LXDE
to work for you.  There are some messages in the archives of
this mailing list which give the steps.  I do not use LXDE but
Jonathan Nadeau and a few others have posted about this in the
past.

Bonne Chance, Alex M

Install the "speech-dispatcher" package then, run spd-conf

Hmmm. I've installed one. Even after spd-conf, I've nothing
else. But right, at this time, I've not installed any speech
synthetiser (espeak). I hope I'll be able to use braille
only. I needn't speech synthetiser usually.

Is there a reason you don't want python3?

I try optimizing at maximum my system and as I use python2
for most applications, I'm not so happy if both python2 and 3
are installed. Both would be large on the system. And most
apps don't support python3 yet. Well if I cannot do better,
I'll install it, but first, I'd ;ike to know if I can use
Python2. I also don't know if I don't risk conflicts between
modules and releases.

Sincerely,

No I don't. I only see, via xbrlapi, "Screen reader
orca" (so a window whose title is "screen reader
orca"). But indeed, I don't have "Welcome to orca".
Thanks for your help.

Hi,

I'm in progress in my experiences, but still not
with an orca. I explain. I use openbox, and I run
orca from an xterm terminal. I issue: orca
--enable=braille I have nothing. orca runs, but
nothing seems to appear, including the preferences
window. I precise at-spi2-registryd is running.

So I run, while xterm is running and on a terminal
(tty1): DISPLAY=:0 orca --enable=braille

On the console, I get: File
"/usr/local/lib/python2.7/site-packages/gi/types.py",
line 47, in function return info.invoke(*args,
**kwargs) gi._glib.GError: Could not locate
wnck_screen_get_default: (null)

orca crashes (I can kill it only with a kill -s 9
command).

I precise what I want: running orca from xterm (or
at X boot time via openbox autostart or what else
I'll find), and having displayed the preferences
window. Then, with alt-tab, I could access to OOo
and firefox. Xterm would say "inaccessible" but no
problem, I don't mind.

Is this behavior expected? Does a stack miss in my
system? I still use orca 3.6.2, as I'd like to
avoid Python3 required with latest orca releases. I
have installed pygobject and libwnck. But some
stack must miss in my architecture of
accessibility.

Thanks for your help.

JPM
