KOSD is a simple framework for the KDE Desktop providing an OSD in response to media key presses.

How to install:

Step 1:
If you have an older version of KOSD already installed, remove it completely before proceeding.

Step 2:
To build and install KOSD change to the extracted source directory and type:

mkdir build && cd build
cmake -DCMAKE_INSTALL_PREFIX=`kde4-config --prefix` ..
make install (as root)

Step 3:
Log out and back in to make sure the modules are loaded correctly by KDED (or run kquitapp kded && kded4).

Step 4:
In System Settings go to Shortcuts and Gestures->Global Keyboard Shortcuts. Select KOSD from the components list and reassign your keys as needed.

Step 5:
Go to Workspace Appearance->On-Screen Display to adjust KOSD to your liking.

That's it. Enjoy!

P.S.: Don't like monochrome icons? Then create the file .kde4/share/config/kosd_keysrc. Put the lines


in it and restart the KOSD Keys service.

You can also set the mixer control by adding the line


where name is the name of your desired control (e.g. Master, PCM, ...).


Changelog from 0.8.0 to 0.8.1
* Fixed some power management issues

Changelog from 0.7.1 to 0.8.0
* Added standard methods for battery, brightness and volume, allowing the pixmaps to be kept in memory, which avoids hard disk reads and makes the OSD more responsive

Changelog from 0.7.0 to 0.7.1
* Fixed a possible crash, if no mixer control named "Master" exists

Changelog from 0.6.2 to 0.7.0
* Changed KOSD Keys Service to use ALSA directly instead of relying on KMix

Changelog from 0.6.1 to 0.6.2
* Fixed CMakeLists.txt not to link against libsolidcontrol which is no longer used

Changelog from 0.6.0 to 0.6.1
* Made KOSD Keys Service compatible with KDE SC 4.6

Changelog from 0.5.1 to 0.6.0
* Added support for (Plasma-themed) SVG icons
* Many improvements throughout the code

Changelog from 0.5.0 to 0.5.1
* Fixed the mixer to always use the correct master channel

Changelog from 0.4.2 to 0.5.0
* Split up the monolithic application into a KDED module for the OSD, a KDED module for the key listener, a system settings module and a simple access library allowing any application to use the OSD
* Replaced the old OSD by new, fully Plasma based OSDs. There's now a "standard" OSD similar to the old one and a "compact" OSD similar to the OSDs provided by KMix and Powerdevil

For people who already have hotkeys in place (or dont want to depend on kmix) it would be great if your application could be switched to a mode where it doesn't capture key-events but simply listens for dcop calls wich could have parameters like (QString text,QString icon,int progress,int duration)

Start with a fresh archive extract and run 'make -f Makefile.cvs'. Then proceed as usual. That should help.

Whoops! Looks like I can't follow simple instructions...

Is it just supposed to show up when I adjust kmix volume? I have hotkeys for it and it never shows up.

It's supposed to show up when you press a button on your laptop or keyboard. You just have to configure which button or key you want to do what.
Also read some of the other posts. Some common problems have already been explained there.

BTW, I only just added the 'make -f Makefile.cvs' line to the description a few hours ago, so it's not your fault:-) It's only necessary on systems which only provide automake 1.10 (but also doesn't harm on such with automake 1.9).

 Great Potential

 by Baldrun on: May 26 2008

Kosd looks like a potential replacement for kmilo. Unfortunately it doesn't quite work for me on a ThinkPad T61p with gentoo. I have several problems and wishes:

- Dualscreen: kosd only shows up on one of the screens independent of the cursor (kmilo shows up on the screen with the cursor)

- Placement: Even though I set it to 50%-50% the kosd-box shows up more to the left of the screen (maybe due to dualscreen?)

- Brightness & Battery: I just don't know which files to use, because I have no files called "actual_brightness" and the like on my system

- Missing events: Kmilo is able to grab "ThinkVantage" button, "Fn + Space" (for zooming), "FN + PgUP" (for the Thinklight)

- Customization: Here kosd is really great in comparison to kmilo. I would love to be able to choose my own icons and to alter the displayed text, too.

- Internationalization: I am willing to translate all text into German

For some more inspiration check out kal: http://kde-apps.org/content/show.php/Kal?content=23472

Keep up the great work. ;)

Hi. Thanks for the kudos:-)

Just a few comments:

* Dualscreen
I'm planing to add support for this in a coming release

* Placement
This could be a bug. I'll have a closer look on this.

* Brightness & Battery
There just isn't a single solution that will work on every imaginable system, but the DCOP interface added in 0.1.2 should help on systems that don't provide this information the usual ways

* Missing events
I'll be adding more actions/events in future versions

* Customization
You can of course replace the icons with your own before installing. I'll try to make KOSD a bit more themeable in a coming release

* Internationalization
I'll add i18n support soon (I'll also provide the German translations myself)

How do you like Plasma 5?
 The best KDE Desktop ever.
 Definitely a nice improvement.
 Not decided yet. Haven't tried it yet.
 I do not like some of the changes.
 KDE is taking the wrong way.
 I am still sticking with KDE 3.5.
 I have no opinion, but wanted to vote anyway.
