</I>>><i> 2012/4/7 Jose Jorge <<A HREF="https://www.mageia.org/mailman/listinfo/mageia-dev">lists.jjorge at free.fr</A>>:
</I>>>><i> Le 06/04/2012 22:53, Colin Guthrie a écrit :
</I>>>><i>
</I>>>>><i> Couldn't agree more. I'd say we can happily provide a tool to configure
</I>>>>><i> autologin, but if that is configured, it basically just sets the DM to
</I>>>>><i> gdm, and lets' it do the autologin.
</I>>>>><i>
</I>>>>><i> The fact that gdm is used should be mostly hidden from users.
</I>>>>><i>
</I>>>>>><i> From what I've seen, gdm seems to be the best implementation of the
</I>>>>><i> whole pam and authentication stuff, so this would be my personal
</I>>>>><i> favourite.
</I>>>>><i>
</I>>>>><i> Col
</I>>>><i>
</I>>>><i> Please note that autologin is lightweight and fast, so I use it for very old
</I>>>><i> systems, where even the 30Mb of RAM eaten by gdm count.
</I>>>><i> But I just can agree that if no one has time to fix it, we can drop it. I'll
</I>>>><i> be away from computers for  15 days ...
</I>>><i>
</I>>><i> Does GDM provide change of desktop as KDM does?
</I>>><i>
</I>>><i> My scenario: I have KDE and Gnome and Xfce installed. For system start
</I>>><i> I have autologin set to start KDE.
</I>><i>
</I>><i> I'm guessing you've configured this inside KDE tools rather than inside
</I>><i> the drak* tools? You'll see why I presume that below:
</I>
No, I always use the draktools for system configuration. I am one of
those who would like to differ between system configuration and
desktop configuration.
>><i> But when I am in a KDE session I
</I>>><i> sometimes logout and use the upcoming KDM to start a Gnome or Xfce
</I>>><i> session or even a session on a vt.
</I>><i>
</I>><i> If you use the autologin package, if you logout, you log back in again
</I>><i> straight away (it's a hook inside prefdm which starts the display
</I>><i> manager and it simply runs autologin if it's configured!)
</I>><i>
</I>><i> Now I'd be tempted to make this a "one time operation" e.g. if autologin
</I>><i> works and exits, then we should write a flag somewhere to say "don't
</I>><i> autologin again" i.e. make it only work once.
</I>><i>
</I>><i> This would solve this problem.
</I>
Yes. That's what I want. I have autologin for the first start. If I
log out it is mostly to change desktop or change user, so I can not
use autologin for that.
>><i> Does this work with GDM as well? If so I'm all in.
</I>><i>
</I>><i> Yeah, but keep in mind, we wouldn't be forcing users to use gdm all the
</I>><i> time anyway. What I'd propose (and this is for mga3 remember), is that
</I>><i> if autologin was configured, we'd simply make gdm kick in and process
</I>><i> that autologin.
</I>><i>
</I>><i> If autologin is not configured, or the user has already logged in and
</I>><i> has now logged out, we would just dump you to your chosen DM (i.e. KDM).
</I>
Good.
><i> So we'd only be using GDM as a tool here, not really for it's GUI
</I>><i> specifically. That said, we may have to ensure that when we use gdm in
</I>><i> this way that it exits after the user session rather than reverting back
</I>><i> to it's login screen, allowing the prefdm process to be automatically
</I>><i> restarted and thus giving you your chosen DM.
</I>><i>
</I>><i> Anyway, this can be discussed in more depth after mga2 is out the door :)
</I>
Yes, I was not aware of this being a mga3 plan.
