Dear Felipe.

                     I just released Aurora 0.1.0 for gNewSense 4. The
            following is a
                     summary
                     of the changes in this version.

                           + Added desktop theme.
                           + Added gdm3 theme.
                           + Added GRUB theme.
                           + Added icon theme.
                           + Added installer theme.
                           + Added documentation
            <http://gnsaurora.rtfd.org/>.

                 Thanks for the update. I liked the old version of the
            wallpapers
                 better, as they did not contain those hard edges.


            I agree. I'll revert the change or try something new.


                 Concerning the start-here icons, I did not yet find a
            way to enable
                 those in gnome-shell. There has been an extension
            available for that
                 purpose:

            
https://github.com/fpmurphy/__GNOME-3.2-Shell-Extensions/__tree/master/address@hidden
            
<https://github.com/fpmurphy/GNOME-3.2-Shell-Extensions/tree/master/address@hidden>



                 but it does not seem to work with gnome-shell 3.4 that
            is included
                 in wheezy.

                 It should of course work with alternate desktop
            environments like Xfce.


            I added the icons just in case they are needed to replace
            the Debian
            swirl which is in /usr/share/icons/gnome, but I haven't seen
            the Debian
            logo used in GNOME shell as much as it was in GNOME 2 (a
            good thing, I
            think). In Debian 7 you can can select the icon theme from
            Applications
            --> System Tools --> Advanced Settings --> Theme --> Icon
            Theme. But
            nothing seems to change when you select something there.


                 In the commit notes it also says: added GTK theme, but
            I cannot find it.


            Ah, well, it is supposed to be aurora/desktop/Aurora. You
            wont find the
            actual themes for GTK 2 and GTK 3 because Aurora uses
            Adwaita's (see
            aurora/desktop/Aurora/index.__theme). So,
            aurora/desktop/Aurora is just
            Adwaita but with different backgrounds and the gnewsense
            icon theme,
            which inherits everything from gnome icon theme except the logo.


        I would appreciate if we could have a gNewSense-specific GTK theme.

        As in Parkes it could be based on the default theme, but with
        adjusted colors.

        In Debian Wheezy a transition Adwaita theme has been used,
        meaning it actually uses a slightly modified Clearlooks for GTK2
        and Adwaita for GTK3 only. The theme engine also does not yet
        fully support GTK2 Adwaita (that has been introduced in GNOME 3.6).

        Maybe we could just port the existing GTK2 theme and modify the
        GTK3 theme a bit, to match the color scheme.


    Sure. I'll try that for version 0.2.0
    <https://bitbucket.org/sirgazil/aurora/issue/8/>.

    Marcus, have you noticed an erratic behavior of GDM Greeter (login
    screen)? I've noticed two things:

    * Sometimes the login screen looks like the shell, sometimes it
    looks like fallback.


A similar bug has been reported to Debian already:

http://www.mail-archive.com/debian-bugs-dist%40lists.debian.org/msg1076025.html

    * When there are two users or more to choose, moving between users
    gradually increases the width of the login dialog.


This one has been reported as well:

http://www.mail-archive.com/debian-bugs-dist%40lists.debian.org/msg1074785.html


    I have to check if these have been reported upstream, but they may
    be the reason why Debian defaults to "session-name='gdm-fallback'"
    for the greeter.


And, no, the reason why Debian uses "session-name='gdm-fallback'" by
default is because "session-name='gdm-shell'" requires a compatible 3D
graphics card (see section 5.4 in Debian Wheezy release notes)
<http://www.debian.org/releases/wheezy/i386/release-notes/ch-information.en.html>.

The purpose of fallback is to automatically get activated on low graphics (meaning no 3D). This is why it's called fallback ;)

I am not aware of any bug that prevents automatically fallback to low graphics.

Afaik this is technically done by invoking /usr/lib/gnome-session/gnome-session-check-accelerated on wheezy. I have just commented out the pre-selection of any greeter, so it should stick with the one that fits best for the graphics card.

#[org.gnome.desktop.session]
#session-name='gdm-fallback'
#session-name='gdm-shell'
