In this sensor browser I had the very same sensors provided by "sensors" e.g. nouveau-pci-0100 ∟ temp1 k10temp-pci-00c3 ∟ temp1 it8720-isa-0228 ∟ fan1 ∟ fan2 ∟ fan3 ∟ in0 ∟ ... But not so after the update anymore... There are still other sensors (CPU Load, Disk, Network, etc...) which still work. > Can you run ksysguard from a terminal and see if it's > spitting any error message (or logging them somewhere maybe?) > This is the output from the terminal ksysguard(3168) KSGRD::SensorAgent::processAnswer: Received UNKNOWN COMMAND for: "lmsensors/k10temp-pci-00c3/temp1?" ksysguard(3168) KSGRD::SensorAgent::processAnswer: Received UNKNOWN COMMAND for: "lmsensors/it8720-isa-0228/temp1?" ksysguard(3168) KSGRD::SensorAgent::processAnswer: Received UNKNOWN COMMAND for: "lmsensors/nouveau-pci-0100/temp1?" ksysguard(3168) KSGRD::SensorAgent::processAnswer: Received UNKNOWN COMMAND for: "lmsensors/it8720-isa-0228/fan1?" ksysguard(3168) KSGRD::SensorAgent::processAnswer: Received UNKNOWN COMMAND for: "lmsensors/it8720-isa-0228/fan2?" ... cheers richard _______________________________________________ lm-sensors mailing list lm-sensors@xxxxxxxxxxxxxx http://lists.lm-sensors.org/mailman/listinfo/lm-sensors
