Quoting Stefan Krusche <linux(a)stefan-krusche.de>de>:
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?
FWIW, I've seen this a time or two in Trinity 3.5.13 -- PSB.
