GUI to Control fanspeed in Ubuntu?

Question

is there any GUI Software to control fanspeeds in Ubuntu 18.04?

Solution

fancontrol-gui is a GUI for fancontrol which is part of lm_sensors. It uses the KAuth module of the KDE Frameworks 5 to write the generated config file. Furthermore it communicates with systemd via dbus to control the fancontrol service.

Install the build requirements (tested in Ubuntu 18.04):

sudo apt update
sudo apt install libkf5config-dev libkf5auth-dev libkf5package-dev libkf5declarative-dev libkf5coreaddons-dev libkf5dbusaddons-dev libkf5kcmutils-dev libkf5i18n-dev libkf5plasma-dev libqt5core5a libqt5widgets5 libqt5gui5 libqt5qml5 extra-cmake-modules qtbase5-dev libkf5notifications-dev qml-module-org-kde-kirigami2 qml-module-qtquick-dialogs qml-module-qtquick-controls2 qml-module-qtquick-layouts qml-module-qt-labs-settings qml-module-qt-labs-folderlistmodel cmake build-essential gettext git 

Install fancontrol-gui:

git clone https://github.com/Maldela/fancontrol-gui.git
cd fancontrol-gui
mkdir build
cd build
cmake .. -DCMAKE_INSTALL_PREFIX=/usr -DBUILD_KCM=on -DBUILD_PLASMOID=on
make -j
sudo make install

In case this somehow does not work, it might make sense to first properly setup the CLI/backend. See this mess: askubuntu.com/a/46135/308869
