--- Comment #6 from Arthur Fayzrakhmanov <herald...@gmail.com> --- Maybe, I should fire a report on NixPkgs tracker, because the way I install KDE is just simply: 1. add to my system config services.xserver.displayManager.sddm.enable = true; services.xserver.desktopManager.kde5.enable = true; 2. and then I just rebuilding my system with `nixos-rebuild switch` command. So (I believe) the only way to control this is to make changes to nix-expression from channel. kcmshell5 kwineffects - Voila! This is the right dialog to configure effects! Thank you, I've just tested fuzzy windows and it's working. So, it turns that all KDE5 settings are "hidden", I mean System Settings does not allow me to change configuration. Rather than that I need to use `kcmshell5` to open "right" dialogs. I've run `kcmshell5 --list` and this shows me a lot of options, great! But why these dialogs not available from KMenu? Finally, this issue can be closed, because desktop effects works indeed. I guess that I have KDE4 "System Settings" in KMenu and the question is actually "why?" and "where to find KDE5 one?".
