On Linux Mint 18.3, when I used to install
mdm, the command
sudo apt install mdm would open a prompt such as:
and I would choose the default display manager. Running
sudo dpkg-reconfigure mdm would also open the new window.
On Linux Mint 19 Beta, installing
mdm does not open such a window. How to overcome this?
I just compared step by step on two fresh installations:
- in both cases,
lightdmis installed default and
- with 18.3,
sudo apt install mdmopens a new window, but not on 19 beta.
