Hi, thanks for answering
Actually I didn't delete the .kde directory for pleasure but I had issues with plasmoids and I was stuck. I did it twice because of another issue with the mad scrapie window when I wanted to test what was the elasticity option in the system settings. In both case I lost control on my desktop...
I didn't find a safemod with graphical interface (without theme, customizing, openGL...) so that beginners would be able to modify a setting if it's not supported. A good idea to submit it to the Dev Team?
Anyway i'll try to reinstall KDE, but I find a way to replace KNetworkManager by Wicd at launching so it's not a serious problem enough for me to reinstall Sabayon.
No I'm not illiterate, just from somewhere else =)
