That is, according to its --help output, a dbus service to communicate with modems. I have a laptop and with a winmodem, but I have no use of it. Since it’s a winmodem (with no drivers) I guess modem-manager is failing constantly.
The problem is with modem-manager logging every minute or so, in short bursts, that it is trying to start. I don’t know how to shut it down or where to configure it to stop starting. If I kill the process, it respawns. I never noticed it in 11.0, so I guess this is a 11.1 feature.
Any ideas? Is this a bug to be reported or a misconfiguration on my system?
