I did remove task-xfce-desktop on those systems. It was after I did that 
that those systems stopped loading Xfce.

And, even though I updated aptitude, it didn't switch from xdm to 
lightdm. When I re-installed task-xfce-desktop, xdm was pulled as a 
dependency.

I wonder if there's a problem just with these specific installations 
that is peculiar to the images I used for the installation -- an i386 
and an AMD64 image from about 08/17. Is something like that possible.

With the problems I've seen with these two particular systems, I'm 
tempted to re-install them both from scratch.

Am I to take it that, if I do that now (netinst), the xfce desktop will 
pull LightDM as the default DM?

Yes, I understand. Unfortunately, I didn't think to collect the logs, 
and I wound up purging the packages (and the information I need to 
correct the problem) on both of the systems that were behaving this 
before I thought about it. It was the weekend, and everyone was tired 
and cranky.

;-)

BTW, when I look in aptitude on the older installations, they also show 
xdm as a dependency of task-xfce-desktop, but the metapackage is not 
installed on them.

Best regards,
