Next steps for Ubuntu RTL

Dear list, Uri,

Like you said, Haggai, you prefer waiting until after Nux developers accept
the patch.

I've commented in the merge
request<https://code.launchpad.net/%7Ehaggai-eran/nux/rtl-logical-packing/+merge/85526>as
well.

About changing the default: It should be done in a way that:

   1. Affects only users that have set their locale to an RTL one
   2. Would be inplemented as a package upgrade in existing precise
   intallations
   3. Would take into consideration encrypted homes
   4. Would allow users with RTL localed to override and choose Unity proper
   5. Requires minimum and clear changes to preferably one package so that
   it would actually be accepted into precise
   6. Would be easily revertible with a package upgrade once Unity proper
   has the RTL support

Haggai, I hope you'll be our savior and take it on :) and that my list of 6
requirements doesn't scare you off :) I don't want to sound like a boss but
these really are the requirements I see before us for this approach.

And if you need a hint on where to start, even though I don't know the
session startup process, I would look at the process that runs with the UID
of the user at session startup and launches the shell. Looking at the
process tree, it looks like lightdm, the greeter, starts gnome-session. I
would assume that lightdm passes the choice of shell to gnome-session
somehow. So perhaps gnome-session should be patched to choose Unity-2D for
RTL locale users even when the choice passed to it was Unity proper. If
this is all true and gnome-session can read the user's locale at that
point...

If we find out that there's no good way to make Unity 2D launch instead of
Unity proper, we could perhaps patch Unity proper to replace itself with
Unity 2D when the locale is an RTL one.

I hope that helped.

Thanks and Blessings,

Shahar
