Hello, It looks like Mageia 7 now uses normal systemd configuration 
files to manage display manager, instead of mageia specific files in 
previous version.

So, you can try to create a file '/usr/lib/systemd/system/tdm.service' 
with following content:

[Unit]
Description=Trinity Display Manager
Documentation=man:tdm(1)
Conflicts=getty@...
After=systemd-user-sessions.service getty@... 
plymouth-quit.service systemd-logind.service

[Service]
ExecStart=/opt/trinity/bin/tdm
Restart=always

[Install]
Alias=display-manager.service


Then, you can reboot your computer and TDM should start automatically if 
it was selected in Mageia Control Center.

If this does the job for you, please report and I will update the package.
