Version: unknown (using 4.2.2 (KDE 4.2.2), Kubuntu packages) Compiler: cc OS: Linux (x86_64) release 2.6.28-11-generic some programs would not launch from the start menu, firefox, thunderbird, avant window manager, compiz, emerald, and etc... These applications would not start from krunner either. Started in the terminal, they would run but each would give the error: sh: kde-config: not found It took two days of searching to find a solution and here it is: sudo cp /usr/bin/kde4-config /usr/bin/kde-config
> sudo cp /usr/bin/kde4-config /usr/bin/kde-config This solution is plain wrong, as kde4-config is for kde4, while kde-config is for kde3. This means that those apps require some kde3 piece(s) for some reason. None of them is actually a KDE application, so there isn't much we can do about that. Please report the problem to kubuntu.
