Re: ModemManager not visible in DBus in Ubuntu 8.10

[Cian Masterson <cian masterson gmail com>]

Apologies for the delay in replying to this but I had parked it in the short term.

I have upgraded the device to Ubuntu 9.10 so I'd have the latest version of modemmanager and since the device is running headless I installed the JeOS variant to save disk space and processor load.  Unfortunatey I'm now seeing strange things with Dbus (i.e. it looks like it doesn't exist) that makes me think it was a stupid choice to make if I want modemmanager.  Given that Dbus stands for Desktop bus perhaps I was a trifle naive to assume it would be in JeOS.

Anyway the issue is that if I call 'modem-manager --debug' as root it appears to start ok, but qdbus doesn't start at all.  If dbus is missing then surely modemmanager wouldn't start.....?  Or would it?  I apt-get installed dbus but it hasn't altered much.

Am I missing something or do I need to go back and start again with "proper" ubuntu despite the fact that I plan to run headless?

Probably not, it should work automatically when ModemManager is running.
Can you ensure that ModemManager is actually running when you try to
look for it with qdbus?

If not, try running (as root):

modem-manager --debug

and see what it prints out.
