Did you get any error message? Or error code (return code), i.e. can you say wether that command failed or succeeded?
No nothing it just freezes
Are you able to switch to console (Ctrl + Alt + F[1-6]) and log in?
Nope.
I don't know how Ubuntu handles that stuff, but on Debian you find:
$ cat /etc/X11/default-display-manager /opt/trinity/bin/tdm
Check the contents of that file. I've had this file changed to another installed display manager a couple of times during upgrade of tdm-trinity.
If you can't log in at all, you can try with a rescue or live system from USB or such. Or start with option init=/bin/bash on linux command line to have at least a shell.
Ok, I can try this, next time, in the meantime I re installed it leaving the windows manager to lightdm
The strange thing is: on my actual machine (running 16.04)
the contend of /etc/X11/default-display-manager
Is lightdm
But tdm starts!!!
But on the other machine I don't dare now to run again
sudo dpkg-reconfigure tdm-trinity
