I have just installed TDE-Trinity in my Stretch box. On boot startx
Exactly how did you install it? (moot if anything below solves)
opens x-server-x-org in F7, but the login manager does not appear. /opt/trinity/bin is in the PATH in /etc/profiles, and tdm-trinity is installed, but still no login manager.
Startx is not supposed to open a login manager. It should open a default DE session, which probably should be TDE in your case.
Surely something else must be necessary to cause the login to appear. I looked for guidance in the TDE instructions, but they are anything but clear. Can somebody help me out?
Does /etc/X11/default-display-manager exist and contain /opt/trinity/bin/tdm?
What happens if you try
dpkg-reconfigure tdm-trinity
???
Does
systemctl status tdm.service
show enabled and on :0 and active? It needs to be if you want TDM's login manager working.
