Henrick:
We wrote a spec for feisty to add accessibility functionality to the
login manager, GDM.

This does not look like it will happen as no work has been done in
Ubuntu or upstream on making the themed greeter (which everyone uses
by default) accessible. The folks at SUN have made the old-style one
work with Orca on Solaris.
Some a11y functionality works with gdmgreeter. You would probably find
that Orca and GOK work okay with gdmgreeter, but there are bugs to
be fixed. gdmlogin works better and supports changing the theme
to HighContrast/LowContrast, etc.
For me at least, even that still just breaks on Ubuntu Feisty. Has
anyone tried getting this to work in Ubuntu? The Orca changelog for
2.17.4 suggests adding
<Control>o 1 1000 10000 /bin/sh -c "GTK_MODULES=gail:atk-bridge
ctrun -l child -i none orca -n
-d main-window"
to /etc/X11/gdm/modules/AccessKeyMouseEvents
A few things you should be aware of:
1) You should *not* need to set GTK_MODULES in the command line. Should
be okay to just call "orca -n -d main-window". Unless this is some
weird Orca issue.
2) You should not include the "ctrun -l child -i none" on Ubunutu. This
is Solaris specific stuff to make the AT programs work with SVC (more
specifically to ensure GDM doesn't restart if the AT programs crash).
3) You may not need to use the /bin/sh -c "...". Might be okay to have
the line look like this:
<Control>o 1 1000 10000 ocra -n -d main-window
Thanks Brian for the detailed directions.
OK, I already had something quite similar to this. I select the Plain
greeter, tick accessible login and restart (log out). GDM fails to come
up, only showing the spinner and running the CPU full out, it seems.
I found a log file though! /var/log/gdm/:0.log (attached) seems to show
a conflict with the wacom tablet, which is a specific ubuntu xorg config
(and the one causing GOK problems to crash for a long time)
And sure enough ... commenting out all the wacom stuff in
/etc/X11/xorg.conf brings GDM back to life with the old style greeter. I
guess the wacom settings are needed to to support tablet PCs, so should
probably be fixed though.
Even the themed greeter runs now and Ctrl+o does indeed bring up Orca
(in magnifier mode). Right, time to test the individual options in more
detail ...
