Free gtk warning cannot open display software for linux

Kirocker Music Display is an Amaork script that makes your Kicker (the KDE main panel) rock with your music.
It is a Kicker applet that displays what you listen to in Amarok
You then always know what you are listening to, and watch its cover: it is always visible on your panel.
It allows you to rate your music with one click: you can quickly change the number of stars of your musics from anywhere on your desktop.
To install:
- Extract the archive
- Open a konsole in the extracted folder (in Konqueror, go to the extracted folder and press F4)
- Run this set of command: ./configure --prefix=$(kde-config --prefix) && make && sudo make install
- It will ask your root password to install the applet on your system
- Right click the Kicker, choose "Add an Applet to the Panel..." (once the panel is unlocked)
- Double-click "Kirocker Music Display"
- Start playing a music: the applet is empty when Amarok is stopped or paused, to not annoy you with useless information when you are working
Also included in the package: the Kicker right translucent white background.
How to make the kicker translucent:
- Your screen resolution need to be 1280*800. If not, you will need some artistic skills and a Gimp experience to modify the given background
- Extract the image "Kicker Right Translucent Background.png" located in the Kirocker Music Display archive
- Open your desktop background image with The Gimp
- Drag and drop "Kicker Right Translucent Background.png" to the Gimp window of your background image
- Save the image and set it as your desktop background image
- Right click the Kicker and choose "Configure the Panel..." (once the panel is unlocked)
- Place the panel on the right (click the button on the right)
- Set the size to "Personalized" and enter "96 pixels"
- In the "Appearance" tab, check "Enable transparency"
- Click "Ok" and youre done: ENJOY!
Enhancements:
- This release fixes an issue with big playlists where Kirocker Music Display would hang up, act badly, or not respond.
- It also solves a long-standing tedious crash.
- Kirocker Music Display should be rock solid now.
