[[!meta title="tails-greeter"]]
tails-greeter is shipped in Tails 0.11 and later.
Archive
=======
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.
[[!toc levels=2]]
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.
5. responsible dev:
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.
