![]() How could I prevent it from changing by other users except me? E.g. This thing works! But only for 1-2 seconds, after that, fans go back to system-defined speed ĭisabling pwm works for about 1-2 seconds.Įcho 0 > /sys/class/hwmon/hwmon1/pwm1_enableīut after that, some daemon reverts this value back to 2. I wonder if that's possible just to set pwm1_enable to 1 and pwm1 to 255? Looks like the suggested method should be working, but Ubuntu 20.04 security limitations are more restrictive than other distros' ones. I'd like to avoid using scripts like fancontrol The question itself ![]() I'm using amdgpu-pro drivers, Ubuntu 20.04. I don't want fancy curves, I'm simply trying to force lock static RPM (full-on mode). In Windows, it's possible to tune fans directly from the AMD Radeon driver GUI app. Maybe override kernel-defined values during boot? It seems that there has to be another way around, like some amdgpu config or something like that. To sum up: seems that I can't edit /sys/ amdgpu-related entries at all Part 2 Systemd: rvice: Failed with result 'exit-code'.

The KCM is only build, if the -DNO_SYSTEMD option is unset or set to false. To compile the additional KCM set the cmake option -DBUILD_KCM=on. 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. If you want to compile without systemd support set the option -DNO_SYSTEMD=true. Service name and config file can be set with the options -DSTANDARD_SERVICE_NAME and -DSTANDARD_CONFIG_FILE. You can change the group name with the -DPOLKIT_GROUP_NAME option. ![]() ![]() This will install a polkit rules file allowing members of the group 'fancontrol' to edit the config file and manipulate the systemd service. If you want to avoid authorizing yourself when using the helper you can set the option -DINSTALL_POLKIT=true. 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. KAuth currently doesn't support install prefixes other than where KAuth itself was installed. It uses the KAuth module of the KDE Frameworks 5 to write the generated config file.įurthermore it communicates with systemd via dbus to control the fancontrol service. GUI for fancontrol which is part of lm_sensors.
