Okay, I tested that. Here are the results: Summary: Installing either slim or tdm-trinity overwrites the default display manager to /usr/bin/slim not depending on the way I changed default dm, manually or with dpkg-reconfigure. Note: dpkg-reconfigure slim says: Please be sure to run "dpkg --configure tdm-trinity". But also after doing so, the faulty behavior persists. See below. So, I should create a bug report in trinity bugzilla, I think. Kind regards, Stefan Test results: Reinstalling tdm-trinity: $ cat /etc/X11/default-display-manager /opt/trinity/bin/tdm $ sudo dpkg -i tdm-trinity_4%3a14.0.5~pre42-0debian9.0.0+6_amd64.deb (Reading database ... 156996 files and directories currently installed.)
