=======
|
|
|
|
|
|
This started as an implementation of custom [[todo/boot_menu]] for GDM3 as part of GSoC2011 project.
|
|
|
|
|
|
This page is the entry point to [[design
|
|
|
description|TailsGreeter/design]] and relevant
|
|
|
[[useful information|TailsGreeter/refs]].
|
|
|
|
|
|
The [[project status
|
|
|
updates|TailsGreeter/blog]] and [[timeline|TailsGreeter/timeline]] pages were actively used during GSoC.

How it should look like
|
|
|
-----------------------
|
|
|
|
|
|
0. After GDM is started user is presented with language-chooser-widget
|
|
|
and "Enable persistence?" checkbox. If the user enables
|
|
|
persistence, they are asked their encryption passphrase(s).
|
|
|
0. Choosing language and layout is immediately applied: if
|
|
|
corresponding .po file is available then TailsGreeter is
|
|
|
immediately translated.
|
|
|
0. One can choose to either login directly, or to go to an
|
|
|
options screen.
|
|
|
0. In the options screen:
|
|
|
- admin-password-widget: typing password and confirming makes the
|
|
|
user sudoer with the chosen password; if no password is entered,
|
|
|
the user is not given any admin rights.
|
|
|
0. After logon, desktop must be shown with proper locale and layout.
|
|
|
|
|
|
Requested options details
|
|
|
-------------------------
|
|
|
|
|
|
Developers are encouraged to provide input for various options to be
|
|
|
asked via boot-menu.
|
|
|
|
|
|
### Language
|
|
|
|
|
|
1. name: Language
|
|
|
2. default value: English
|
|
|
3. effects:
|
|
|
- setup locale for the TailsGreeter so that the user can understand the other
|
|
|
choices;
|
|
|
- generate the chosen locale;
|
|
|
- setup locale for the session to be started;
|
|
|
- maybe more: have a look at
|
|
|
`config/binary_local-hooks/20-syslinux_i18n` in Tails main Git
|
|
|
repository to see what parameters it passes to live-config
|
|
|
(locales, keyboard-layouts) then grep the relevant variable names
|
|
|
(`KEYBOARD_LAYOUT`, `LIVE_LOCALES`, `LIVE_TIMEZONE`) in
|
|
|
live-config source to see what is currently done depending on the
|
|
|
chosen language, and might thus need to be triggered by
|
|
|
tails-greeter as well; while appealing, installing `locales-all`
|
|
|
is not an option: it avoids the need to compile locales at
|
|
|
runtime, but it increases the ISO size by 130MB+, which seems
|
|
|
overkill since compiling one given locale takes roughly 3s on
|
|
|
a quite old laptop.
|
|
|
* locale generation: done with localedef (see [[design|TailsGreeter/design]] for details of the interface)
|
|
|
* keyboard: layout is applied with the help of corresponding GDM d-bus signals.
|
|
|
* console keyboard: live-config `015-keyboard-configuration`,
|
|
|
`117-xserver-xorg` and `014-console-setup` scripts might be usable;
|
|
|
need some envvars set.
|
|
|
* Note: live-config scripts we'll run ourselves must not run on boot
|
|
|
before we run them: these scripts are *not* idempotent
|
|
|
4. ui hint: Choose the language of your Tails session.

6. dev's notes: This item should be really visible, probably on top of the
|
|
|
TailsGreeter screen. More information can be found in
|
|
|
[[todo/localization_at_runtime]].

### Administrator password
|
|
|
|
|
|
1. name: Administrator password
|
|
|
2. default value: none
|
|
|
3. effects: execute `set-user-password-and-locale` with `$TAILS_USER_PASSWORD` saved into temporary file. See [[design|TailsGreeter/design]] for details.
|
|
|
4. ui hint: (draft) enter here a password that will be asked to grant administrator
|
|
|
rights. Leave this field blank to disable administrator rights.
