Fresh CentOS 7, patched, added repos for EPEL, NUX, whatever else was listed. Accidentally installed "trinity-tdebase" first. Pulled all those packaged and then installed "trinity-desktop-all".
"systemctl disable gdm.service" worked and kdm/xdm failed (likely because I don't have those installed) but this fails:
systemctl enable tdm.service Failed to execute operation: Access denied
Adding -f to the end doesn't seem to make a difference. Moderate googling is not helping! I've rebooted several times with no apparent effect.
Since it behaves identically when I try tdm.service as it does when I try xdm or kdm, is it possible that I'm missing a step somewhere?
This system was Ubuntu+TDE and while I've been fiddling with RHEL/CentOS for ages, CentOS and it's systemctl are still new to me. Never was a Fedora person.
