Thank you everybody for your help. One more question please.
Polite and grateful requests, deserve support!
In /home/.config are only configuration files. The program itself is mainly located in /usr/xxx/xxx
If a program is installed via pisi, you can remove the software with package-manager.
Very simple, isn´t it?!
I removed cairo-dock 2.1.3-3 because this version seems to have issues. I can´t get the plugins running.
With V. 2.1.0 everything is okay. Also the supercool effects like 3D-Icon-Rotating!
You will find cairo-dock and plugins V2.1.0 in the PardusUser.de reposority in the next few days.
The only disadvantage of V2.1.0 is, that there are only three themes integrated and other themes have to added manually.
After a working cairo-dock (version greater than 2.1.3) is available i will upgrade the version in the repo.
