Cannot Get To Bottom Panel with Accessibility
I am a member!
Hi, List!
I am pleased to learn about Trisquel 5.0, i18n edition, especialy its
included accessibility for users with visual impairment. I am a regular
user of the Vinux distribution, giving Trisquel a look. Presently, it
is running from a flash drive installation.
Normally, when working in Gnome and using the Orca accessibility, I
would use the keystroke 'ctrl+alt+tab' to cycle among the desktop and
panels. Here in Trisquel, I find that this keystroke does not work,
leaving the panel unreachable without the mouse or a sighted helper.
How do I enable the standard gnome keystroke 'ctrl+alt+tab'? If
Trisquel has moved this shortcut, what is it?
Thanks for your help!

I don't use accessibility programs, but pressing ctrl+alt+tab on my
Trisquel 5.0 installation does what you described. In System >
Preferences > Keyboard Shortcuts this shortcut is binded to the action
"Move between panels and the desktop, using a popup window".

Thanks!
I was doing the live session from a flash drive installation. The
shortcut is not bound; I looked in Keyboard Shortcuts. Can you check
your live session; is it bound there, as well as in your installed system?
Thanks,
Dave Hunt.

It's bound in the live sessions too. In accessibility mode or without
the accessibility. David might be right about Compiz, since my system
runs without it.
Hi! I suspect that shortcut works as desired when using the standard metacity window manager, but in compiz --which is default in supported hardware-- it is bound to another operation. You can easily change the window manager to metacity with the command (you can enter it at the Alt+F2 prompt) "metacity --replace" without the quotes, or by disabling desktop effects in gnome-appearance-properties's last tab.

Hi, David,
Thanks for your suggestion of the "metacity --replace" for enabling the
keyboard shortcut with which I have trouble. Once the command is given,
the shortcut works as it should. How do I set metacity as my default
window manager, and have the setting persist? Now, I have to give the
command on each login. I'm running a thumb drive installation of
Trisquel, in which orca settings and other files persist across sessions.
Thanks for your help,
Dave Hunt

In the "Visual Effects" tab of the "Appearance" window you can open from the "System/Preferences" menu, select "None". If your Live system is "persistent", this setting will be saved.

Hi,
I cannot see a Visual Effects tab on Gnome appearance preferences, I
only find Theme, Background, and Fonts. None of those seems to have an
Effects section. This is on both my Vinux installation and on my usb
installation of Trisquel 5.0. Vinux is also based on Ubuntu 11.04.
Both systems run on an Asus 1015 PE netbook. In Vinux, the subject
keyboard short works, and "classic gnome, no effects" is the default
desktop as shown in administration->login screen preferences. Maybe
I'll change the window manager to metacity in
"/usr/share/gnome-session/sessions/classic-gnome.session", on the
Trisquel usb?
Thanks,
Dave Hunt

I am not sure. One way that should work is to execute gconf-editor, navigate to /desktop/gnome/session/required_components and set the key "windowmanager" to the value "nautilus". Instead of all this navigation, the value can be changed in one command: ;-)
$ gconftool-2 --set -t string /desktop/gnome/session/required_components/windowmanager nautilus
Alternatively, you can add the command 'metacity --replace' to the "Startup Applications" (in the "System/Preferences" menu). However, in this way, I believe Compiz is started beforehand what is a waste of time and energy.
That is strange that the Live system has a different Appearance window than an installed one!

I replaced "gnome-wm" with "metacity" in both
/usr/share/gnome-session/sessions/classic-gnome.session and
/usr/share/gnome-session/sessions/gnome.session. This seems to have
fixed the access to the panel.
Thanks,
Dave

I believe this changes the default window manager for all users of the system (but you probably are the only user of your Flash drive). I also believe that an update of gnome-session-common would overwrite your change (but you probably do not update the software on the Live system).
In this end, making the change in GConf (as explained in my last post) probably is a better idea.

Thanks!
I'll leave the flash drive as-is, with metacity the default for all
users, since live session is the only user of the flash drive, and the
drive is intended as a demo, probably for other users who are blind.
When I install Trisquel to this machine's hard drive, I'll make the
change you suggest below, that is, to add "metacity --replace" in the
startup apps for my session. I assume this is what you mean by "gconf"?

Adding "metacity --replace" to the startup applications is inefficient because Compiz is loaded and then replaced by Metacity. It is the first solution that I mentioned that uses GConf and should be preferred. Here it is again:
"Execute gconf-editor, navigate to /desktop/gnome/session/required_components and set the key "windowmanager" to the value "nautilus". Instead of all this navigation, the value can be changed in one command:
$ gconftool-2 --set -t string /desktop/gnome/session/required_components/windowmanager nautilus"
I think it should be metacity instead of nautilus.

Now running Trisquel from my hard drive, and did not do the 'metacity
--replace' inefficient option. Once I had it running from hard drive,
Orca showed me the visual effects tab, where I set the value to 'none'.
The system works as I want.
Cheers,
Dave
