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?
First, a you sure that slim wasnt updated too? Because if it was it is most likely bug in slim. If not than this looks like a problem with debconf database (or a bug in debconf). Look in /var/cache/debconf/config.dat for shared/default-x-display-manager and post a context of this section
