Re: [orca-list] Emacs and Orca again

["Bart Bunting" <bart ursys com au>]

Hi Peter,

What I meant was that I used to launch emacs from a console with the DISPLAY
environment variable set to :0.  The effect of this was that when I ran
emacs the emacs window would appear on my gnome desktop even though I had
launched it from tty1 or whatever.

Doing it this way meant that orca and emacspeak would both function
together.  I was able to use orca normaly and when I switched to the emacs
window orca would simply say "emacs inaccessible" and emacspeak would take
over.  
I must add that if I launched emacs from the gnome run prompt (alt f2) or
from a gnome-terminal it would hang orca and or emacs.  Although the effect
appeared to effect orca more than emacs because when the emacs window had
focus emacspeak would function normaly but when alt tabbing away orca would
hang.

Another effect is that if you launch emacs and do a few alt tabs or
something nothing is spoken.  However if you then switch to a console and
kill emacs there is a flurry of speech from orca sort of like it is now
catching up.

The current situation is that If I launch emacs from either the tty or from
within gnome it hangs orca.

I have also tried the daemon mode of emacs, that is the multi-tty support in
emacs 23.  

Something like "emacs --daemon" will launch emacs in daemon mode and then
"emacsclient -c" from within gnome brings up an emacs window connected to
the emacs daemon process.  I can report that launching emacs in this way
still appears to have orca hang.

Now I'm not sure if it is emacs, orca or the window manager that is to blame
here.

I'd really like to nail down who is at fault here so I can hassle the
appropriate party to get a fix if at all possible.

Any further insite would be greatly appreciated.

Regards

Bart

Another datapoint on this.  First note that I'm using FC-10 which
means gnome-2-24 and emacs-22.3, not exactly the latest and greatest.
However:
I usually run emacs/orca as Bart originally suggested:

Which is not what I understood from the first message but I digress.
I usually
boot to runlevel 3
start emacspeak on virtual console 1
switch to VC2
login then run startx
All proceeds happily until:
For various reasons I need to restart the emacs on VC1
then everything hangs.
This happened even when I remembered to add the -nw flag to the
emacspeak startup script.  Tentative conclusion: order seems to
matter.

I used to run emacs directly under sawfish rather than in
gnome-terminal and that worked fine but was also years ago.
Getting emacs back as a self-voicing application under orca would
certainly be nice. Is the bad emacs/gnome interaction bug logged
somewhere? The closest I see are the Ubuntu bugs 185366 and 183245
which don't appear to have been resolved. 
cheers
Peter
