A Canonical desenvolveu algo chamado FWTS que testará sistematicamente os recursos da ACPI fornecidos e informará sobre sua saúde e possível correção. soluções. Execute-o e poste o conteúdo aqui (pastbin, por favor) e para um bug da barra de lançamento contra o kernel linux.
No mínimo, execute os testes "thermal_trip fan".
[continuou usando os resultados do FWTS]
Test 2 of 2: Load system, check CPU fan status. Test how many fans there are in the system. Check for the current status of the fan(s). Loading CPUs for 20 seconds to try and get fan speeds to change. Fan cooling_device0 current state did not change from value 0 while CPUs were busy. Fan cooling_device1 current state did not change from value 0 while CPUs were busy. Fan cooling_device2 current state did not change from value 0 while CPUs were busy. Fan cooling_device3 current state did not change from value 0 while CPUs were busy. Fan cooling_device4 current state did not change from value 0 while CPUs were busy. Fan cooling_device5 current state did not change from value 0 while CPUs were busy. Fan cooling_device6 current state did not change from value 0 while CPUs were busy. Fan cooling_device7 current state did not change from value 0 while CPUs were busy. ADVICE: Did not detect any change in the CPU related thermal cooling device states. It could be that the devices are returning static information back to the driver and/or the fan speed is automatically being controlled by firmware using System Management Mode in which case the kernel interfaces being examined may not work anyway.
OK. Isso confirma o problema, não há feedback.
Não parece que você tenha o módulo asus-laptop instalado. Às vezes estes módulos de suporte específicos para laptop fazem o truque para esses componentes
$ sudo modprobe asus-laptop
Isto parece ter funcionado ao mesmo tempo, Ubuntu 12.04 na velocidade do ventilador asus n76vb não está funcionando , o que tornaria o seu caso uma regressão. Infelizmente, nesse caso, o remédio foi "eu atualizei um monte de coisas e funcionou": (.
