Ubuntu – .dbus folder in home folder belongs root

dbuspermissionsroot

I have a folder ~/.dbus in my homefolder that is only read and writeable by root:

drwx------  3 root  root  4096 Feb 17 17:30 .
drwx------  2 root  root  4096 Feb 17 17:30 session-bus

Is this the correct setting? Or if not, how could that happen?

The reason for these being created with root ownership in the first place is usually the way sudo preserves some user environment. ls: cannot access .gvfs: Permission denied

That folder .dbus and .cache with all it contents is supposed to be owned by the user whom the home directory belongs to. It is usually safe to delete either, it will be recreated next time you login (it is just a cache that would have gone obsolete eventually).

# be careful what you type when you use rm -rf!
sudo rm -rf ~/.dbus

Keep in mind that .gvfs behaves somewhat special since it's a mount point (check the output of mount to confirm). As long as you have network folders mounted, don't touch it.

You can either do something like this:

bus = dbus.SessionBus()
bus.call_on_disconnection(your_method_to_do_stuff)

Or you can connect to the NameLost signal on the org.FreeDesktop.DBus interface. The former doesn't let you pass additional arguments, and your method can only take the bus connection object itself as an argument. The latter is a bit more complicated, but doesn't seem to allow passing in other arguments of your own accord either, and you are limited to taking the arguments which the signal itself sends, which in this case is a string of the message bus name your process formerly owned.

On the other hand, if your process does stay around after that, you should theoretically get a SIGKILL at some point as well.
