I tried to run dcop, since my yakuake cannot be shown again in my Cinnamon, and I don't want to restart my yakuake. I found that this command can make my yakuake show again:

dcop yakuake DCOPInterface slotToggleState

But I got no luck running it:

$ dcop
No command 'dcop' found, did you mean:
 Command 'dtop' from package 'diod' (universe)
 Command 'dccp' from package 'dcap' (universe)
 Command 'bcop' from package 'compiz-fusion-bcop' (universe)
dcop: command not found

I've tried to search it, but no luck:

$ apt-cache search dcop
courier-filter-perl - purely Perl-based mail filter framework for the Courier MTA
gambas3 - Complete visual development environment for Gambas
grace - XY graphing and plotting tool
jless - A file pager program, similar to more(1) supporting ISO2022
konversation - user friendly Internet Relay Chat (IRC) client for KDE
xgraph - Plotting program, reads stdin, allows interactive zooming

So, in which package dcop application is contained?

What's dcop exactly? It seems not to be packaged in Ubuntu. Can you point to a web page or source? – gertvdijk Jan 17 '13 at 1:27

It's obsolete and has been removed

DCOP the protocol is now being handled by D-Bus, the former dcop command is an old KDE thing.

It's even in the Wikipedia: DCOP page you provided yourself!

DCOP was replaced by D-Bus in KDE Software Compilation 4.


D-Bus, a message bus system standardized by, was heavily influenced by the DCOP system and replaces DCOP in KDE Software Compilation 4.

So, have a look at the possibilities the dbus-* commands can do for you.

I think you were looking at a very old or mixed up sources, as Cinnamon is quite new thing while this has been obsoleted since the release of KDE 4 in 2008.

Move to D-Bus

In KDE, to toggle the window state of Yakuake Terminal emulator, do this (verified working):

qdbus org.kde.yakuake /yakuake/window toggleWindowState

How to get this working in Cinnamon? Not sure, as Yakuake is a KDE program and I'm not familiar with non-Qt D-Bus implementations.

ok many thanks.. i've found the dbus (qdbus command) but it's not working.. so i give up for now.. XD – Kokizzu Jan 17 '13 at 10:18
@KiswonoPrayogo Try the command I used. While still not clear what you wanted to accomplish to start with, this example is working for me. The slotToggleState state seems not available as an option to /yakuake/window. – gertvdijk Jan 17 '13 at 10:27
no, it's not working.. | the problem: sometimes KDE global shortcut stopped working, so i can't call yakuake back, even by calling yakuake from gnome-console again.. it wont show up.. – Kokizzu Jan 17 '13 at 11:29
@KiswonoPrayogo What do you mean "it's not working"? Do you get an error message? Does Yakuake do something else? What exact command did you try? etc. – gertvdijk Jan 17 '13 at 11:37
@KiswonoPrayogo then I'm lost as to what is different in your set up. You could try debugging and finding another way using qdbusviewer, e.g. the raiseSession method. – gertvdijk Jan 17 '13 at 12:34

According to Ubuntu Package Search :

It is contain in kdelibs until lucid (Ubuntu 10.04).

This is the completion hinting on dcop as far as I can see. – gertvdijk Jan 17 '13 at 1:26
@gertvdijk good point, re-do search. – John Siu Jan 17 '13 at 1:32
