Good day everyone,

I'm using trinity 14.0.5 from preliminary stable builds on devuan ascii (debian 
stretch).

Through the most recent upgrade, that I executed on 2018-07-02 11:42:01, tdm 
(amongst a couple others) got upgraded:

tdm-trinity:amd64 (4:14.0.5~pre39-0debian9.0.0+6, 4:14.0.5~pre42-0debi
an9.0.0+6)

After this upgrade tdm wouldn't start anymore and in /var/log/boot I found this 
error message:

Not starting Trinity Display Manager (tdm); it is not the default display 
manager.

The file is there:
$ ls -l /etc/X11/default-display-manager
-rw-r--r-- 1 root root 14 Jul  2 11:42 /etc/X11/default-display-manager

And it says:
$ cat /etc/X11/default-display-manager
/usr/bin/slim

Solution:

$ dpkg-reconfigure tdm-trinity

Of course, tdm was the default display manager already before the upgrade, and, 
as you can guess from the above, slim is installed, too.

I think, it should not be necessary to reconfigure the display manager, or, 
least, the user should be prompted to do so at installation.

IIRC, this happened already at the previous upgrade to ~pre39.

Has anybody seen this? Do you think it is a bug?

Regards,
Stefan
