Changing Desktop in Ubuntu 11.10

[Hammer Attila]

	Hy Dave,

Feel free you put with you worked final steps with a Wiki page, I am not 
have accessing yet any Wiki page. Of course if you suggest me a Wiki 
page with have public editing possibility, I welcome doing this.
To any user possible doing a good working fallback session style 
desktop, need doing other steps, because for example the factory 
awailable GNOME main menue not possible accessing keyboard the third 
"System" menue awailable functions.
Because not have better method yet, I deleted entire top panel, created 
a new panel, and added following applets before I not found 
jconti/gnome3 PPA and the GNOME3 ported indicator-applet packages:
- clock
- Notification area
- Main menu applet
If any user would like installing indicator-applet-complete GNOME3 
ported package and want add the all indicator applet in the panel, to 
get good visual lookup not need adding I think the clock and 
notification area applet, but I am not full sure this, so this is need 
confirming a sighted or partialy sighted user.

This changes resulted me an one column dropdowned main menue with are 
possible accessing all now missing importanter menu items (actual 
username related submenue with possible changing the status and launch 
system settings preference tool, shutdown, switch user, logout menu items).
Have a disadwantage this method, if you press ALT+F1 keystroke, Orca 
does'nt spokening the first awailable menu item, because the first menu 
item is not focused automaticaly I think the GNOME Main Menu applet.
If future hopefuly resolving developers following bug, this step doesn't 
need:
https://bugzilla.gnome.org/show_bug.cgi?id=662913
Launchpad bugreport link is following:
https://bugs.launchpad.net/bugs/846254

Because I added the "all indicators" applet my top panel, if I press 
Super+S keystroke, I see all installed indicators, similar with Natty. I 
very wait when Precise officialy awailable the GNOME3 ported indicator 
applets, but before this is happening, developers need resolving 
following bug:
https://bugs.launchpad.net/bugs/724369

If I remember right, when an user installed the gnome-session-fallback 
package and first doing the session change, the ALT+F1 and ALT+F2 
keybindings are disabled, so this keystrokes need assigning with proper 
functions in the GNOME Control Center Keyboard preference pane. Need 
going the keybindings page, choosing the "system" section and associate 
the proper commands with the ALT+F1 and ALT+F2 keybindings.
I using now my testing Precise system this way with GNOME3 fallback 
session without any problems.

The best desktop session switch method I think Luke suggested command, 
but I don't no why not working right the suggested command with I pasted 
my letter in Orca-list.
Possible not a full elegant way session change method with editing the 
/var/lib/AccountsService/actual username related file and changing 
direct the session if have a better alternative, better put I think Luke 
working command a Wiki page, because this command doing session change 
on the fly if I understanding right Luke pasted letter part.
The pasted letter part is following:
"Ok, here is a command that should change your session to unity-2d, 
without you having to log out and stop lightdm. This should worok 100%.

You need to know what your user ID is, not your user name your user ID 
number. To find this out, open a terminal and run:

echo $UID

Make a note of the number you hear, you will need it in the next 
command. To make the change, run this command:

dbus-send --type=method_call --system --reply-timeout=1000 
--dest=org.freedesktop.Accounts /org/freedesktop/Accounts/User$uid 
org.freedesktop.Accounts.User.SetXSession string:ubuntu-2d

Where $uid is your user ID number, mine is 1000.

accessibility at login will certainly be fixed for precise, and may be 
fixed in oneiric as well, depending on how invasive the fix is.

Hope this helps."
