I should think that this would continue to work, as the migration will
be a one time operation on upgrades only.

I guess this could actually be in the postinst of ubuntu-session itself
if we make sure that it is configured before gdm3 (e.g. by Depends:
ubuntu-session ← gdm3, assuming there's no circular dependency problem
[all of the Depends of ubuntu-session are already in Depends of gdm3 so
we won't pull any extra packages onto users' systems]).

And I think we'd only do it when upgrading to this version, so this
check would not fire for new installs or any subsequent upgrade if the
user changes the setting back.

Good idea — so if we need to do need to port the default sessions over
from lightdm → gdm3, we could maybe do this in the same script and then
this could remember if it ever saw 'ubuntu'.

Right now I think this might be the best we can reasonably do. Some
people will get moved onto gdm3 when they are using flavours that want
to stay on lightdm, if they also have ubuntu-session installed and
another user on their system, but in that case we can release note /
document the way to switch back.

Cheers,

If the prompt is removed how user will make lightdm default display manager when switching from gdm3 to lightdm? Will  'sudo dpkg-reconfigure lightdm' still work? Beside many users have multiple sessions installed. How will it work in this case?

Thank you for kicking this off upstream! Looks like this is now under
active consideration and development by upstream.

Given that this is now making progress upstream, I suggest that in
Ubuntu we go with what upstream decides to do: turning SMB1 support off
by default when we update to a release where they do that. Unless they
(or our security team) suggest that we do otherwise.

My heuristic would be for avoiding the prompt:
- ubuntu-session installed
- that session is set as current session for at least one user on the
machine.

Ubuntu Desktop transition from LightDM to GDM

Ubuntu Desktop will be switching from LightDM to GDM for 17.10.  I'm working on handling that transition and trying to sort out the best solution for upgraders that won't negatively impact other flavors.

The initial plan was to drop the current prompt when configuring the package to select which DM to use by default and just switch current lightdm users to gdm3.  This would only affect users that have both lightdm and gdm3 installed, but I can see cases where users may have that today.   For example an Ubuntu MATE user that has also installed gnome-shell, would have both lightdm and gdm3 installed.  Most of the flavors are using lightdm and as far as I know aren't planning to switch to GDM at this time.

We could use a maintainer script to switch the default to gdm3 on upgrade only if ubuntu-session is installed, this would further reduce the impact.  

Thoughts, concerns or suggestions all appreciated. 


Thanks,
Ken

Re: Hanging builds on s390x

From [1] to [2] we found [3] being a fix.

Yet why this doesn't hit other architectures than s390 nor Debian-s390x is still a riddle to solve.
In case you are interested, details are in the IRC log.

Good luck Mitya57 to track the rest down!
