Version: 4.4.2 (using KDE 4.4.1) Compiler: gcc 4.3.4 OS: Linux Installed from: Gentoo Packages http://bugs.gentoo.org/show_bug.cgi?id=312513 KDE 4.4.2 <--- The kdebase-workspace-4.4.2 cmake files detect for the presence of libxinerama at build time. If it's there, it is enabled and linked, and there is no way of disabling this on the command line. This affects ksplash and systemsettings. See above url for more info and a workaround patch.
Issue is introduced by FindX11.cmake, and I think in longer run this module should be split to separate CMake modules (FindXinerama, FindXRender, FindXRandr etc) as those libraries are actually distributed separately since X.Org was forked off from XFree86
This is really old, is this still a problem in Plasma 5?
