login-screen has no user-pictures with encrypted home directories

Thanks for the report.

Obviously, this is because your home directory is not mounted at the time in which gdm tries to read your .face file.

To solve this, we're going to need to read/write .face to a non-encrypted location. The best place for this is going to be /home/.ecryptfs/$USER.

gdm will need to be modified to check this location for .face.

And gnome-control-center will need to be modified to write .face to that location too, if it exists.

Attaching a fix for gdm. I've tested that it does the right thing, looking for a .face file in /home/.ecryptfs/$USER/.face.

I'm hoping that seb or pitti will have a look at this, upload to Ubuntu, and take care of upstreaming to Gnome.

Thanks,

Attaching a fix to gnome-control-center, that fixes the about-me dialog to write .face to /home/.ecryptfs/$USER, if that directory exists.

Again, I've tested it and it does this. Subscribing seb and pitti, hoping that they'll have a look over it, upstream it to Gnome, and upload to Karmic.

Thanks,

Some notes about the gdm patch:

- First doing asprintf seems superfluous, it could all be done in one step in the g_build_filename() call.
- ~/.dmrc needs the same treatment

Taking the gdm side.

upstream fixed the issue by using a cache dir, see https://bugzilla.gnome.org/show_bug.cgi?id=565151 for details it will be in GNOME 2.28 next week

Brilliant!

Does this, by chance, also work with NFS or other network mounted home directories? This might be a good fix for bug #23002...

gdm (2.28.0-0ubuntu1) karmic; urgency=low

  * New upstream release (LP: #434354)
    - Now GDM supports the ability to specify the automatic/timed login user via
      a script via the same interface that the old GDM supported.
    - Now the user's dmrc and face image files are stored in /var/cache/gdm, so
      that the login process does not need to access the user's $HOME directory
      before authentication.
    - Fix the login GUI options widget so the language/session/layout choices
      are not reset after a failed login.
    - Fix language dialog so it does not crash if the user click's the "OK"
      button when no language is selected.
    - Fix to ensure that the login dialog regains focus after the language or
      layout dialogs are used.
    - The language dialog has improved logic to sort the language names more
      correctly.
    - Make sure to check error variable is not NULL before referencing it in the
      gdm-user-manager code.
    - Make sure to not print NULL strings since this causes crashes on some
      platforms.
    - Improve documentation.
  * debian/patches/09_gdmsetup.patch: updated:
    - Filter ConsoleKit system users (LP: #432271)
    - Make window size fixed (LP: #429206)
  * debian/patches/01_default_keyboard_layout_hal.patch,
    debian/patches/99_autoreconf.patch: updated.

I'm sure this is related, but may be better if reported as a separate issue. I'll post it here first to see what the general consensus is.

In the shutdown menu, there is a list of users for switching accounts. For accounts without encrypted profiles, the image linked to their profile is displayed, but for those with encrypted profiles their image does not display.

The bug appears again under Ubuntu 10.10 beta.

I can't agree - due to the updates took place last days, the user picture has been deleted meanwhile.

After reset --> System -> Preferences -> About Me --> User Picture

the user picture is shown again inside the login-screen continuous.

Yes, this is what I did. And I repeated it minutes ago and the picture disappears again. Not every booting-up, but 1 out of 5 times.

And yes, my system is up to data. System installed on 2010-09-15. Do I miss anything? Perhaps this is the wrong bug because I don't use any encrypted home directory ;-)

is that still an issue in Oneiric?

No - it works without any restrictions - if you are using "gdm", not "lightdm"!

I can change icons of users with and without encrypted home, and see them in the user menu indicator. However, unity-greeter doesn't show any pictures at all (independent of encryption status). This should become a separate report, though.

there is already a bug about the unity-greeter feature request
