[this is completely off-topic on lightdm list please switch to
pkg-xfce-devel so we can fix the Xfce/Debian part]

Check that nothing else has been removed by aptitude.

Yes, as I said, the update has been done in tasksel repository but it
will take time before it reach testing and images are starting to be
made with this change.

Not sure it'll do anything.

No, not yet.

Ok, now, please do:

* install task-xfce-desktop
* install lightdm
* switch default greeter to lightdm (dpkg-reconfigure lightdm should

When LightDM starts, select “Xfce session” in the dropdown menu.

Does it work?
