fancontrol-gui

A GUI for fancontrol which is part of lm_sensors https://github.com/lm-sensors/lm-sensors. It uses the KAuth module of KDE Frameworks 5 to write the generated config file. Furthermore, it communicates with SystemD via DBus to control the fancontrol service.

KAuth currently doesn't support install prefixes other than where KAuth itself was installed. If you want to use another install prefix, you have to run the application as root or another user with the necessary privileges to avoid the KAuth helper.

If you want to avoid authorizing yourself when using the helper you can set the option -DINSTALL_POLKIT=true. This will install a Polkit rules file allowing members of the group 'fancontrol' to edit the config file and manipulate the SystemD service. You can change the group name with the -DPOLKIT_GROUP_NAME option. Service name and config file can be set with the options -DSTANDARD_SERVICE_NAME and -DSTANDARD_CONFIG_FILE.

If you want to compile without SystemD support set the option -DNO_SYSTEMD=true.

If your distro looks for QML plugins in /usr/lib/qt/qml instead of /usr/lib/qml you need to set the option -DKDE_INSTALL_USE_QT_SYS_PATHS=true.

To compile the additional KCM set the CMake option -DBUILD_KCM=on. The KCM is only built, if the -DNO_SYSTEMD option is unset or set to false.

To compile the additional KDE Plasma plasmoid set the CMake option -DBUILD_PLASMOID=on.
