If xf86gammaxfg isn't installed, your distribution probably didn't compile it. Could you ask for build logs?

I see that xf86gammacfg (typo'd in bugreport and comments, sorry), has indeed not been built. Only the docs and kcmkgamma are being built.

I've checked in several several repos (arch, aur, kubuntu) that package KDE and none of them seem to be building xf86gammacfg.

I looked at the kgamma5 git and in CMakeLists.txt, the xf86gammacfg subdirectory is commented out. Is it possible that it is not getting built and therefore not getting installed by any of the packagers because of this oversight?

Thanks for your help.
