I'm under Linux Mint 18.

I'm delving into qdbus tutorials: all say I should be able to list a bunch of services with "qdbus" from a terminal. It runs but only returns org.freedesktop.DBus, none of the org.kde services:

Code: Select all

    root@Spectre ~ # qdbus
    :1.10
    :1.12
    org.freedesktop.DBus


I'm trying to figure out how to switch between Activities in a script. Theoretically,

Code: Select all

qdbus org.kde.kactivitymanagerd /ActivityManager/Activities ListActivities

should give a list of Activity IDs, but I get:

Code: Select all

    root@Spectre ~ # qdbus org.kde.kactivitymanagerd /ActivityManager/Activities ListActivities
    Service 'org.kde.kactivitymanagerd' does not exist.


so I'm kind of stuck. All help appreciated.

Thanks in advance.
Andy

root@Spectre ~ # qdbus


root?

Is that where your KDE services are?

Thanks, I have tried both as root and as user, the results are the same:

Code: Select all

andy@Spectre / $ qdbus org.kde.kactivitymanagerd /ActivityManager/Activities ListActivities
Service 'org.kde.kactivitymanagerd' does not exist.


I ASS-U-ME that using root short circuits possible permission conflicts...

However, now that you have inspired me, I find:

Code: Select all

qdbus org.kde.ActivityManager

DOES work—no "d" on Activity Manager...

and further,

Code: Select all

andy@Spectre / $ qdbus org.kde.*


does indeed give a long list.

So, thanks for the inspiration: [This] problem solved...

Now on to the next!

Every user gets their own DBus session. (plus there's a separate global "system" bus)

Use qdbusviewer, it'll make your life 10x faster.
