Nos últimos 2 anos, tenho tentado mudar definitivamente meu laptop do Windows para o Linux, mas tem sido uma luta constante. Eu tenho um MSI GE40 com CPU Intel i7 4800MQ.
Acabei de instalar (16/03/2017) o Ubuntu 16.04.2 LTS na esperança de que todos os meus problemas fossem resolvidos e, aparentemente, a maioria deles são, mas este ainda permanece.
Quando inicializo no Ubuntu, a temperatura da minha CPU é de cerca de 60º Celsius, após apenas 30 minutos de uso (não uso pesado, apenas um navegador com 2 ou 3 guias e um Terminal - loadaverage abaixo de 1) a temperatura aumenta para 87º Celsius. O notebook começa a ficar lento e muito quente.
O comando "sensores" foi usado para obter a temperatura da CPU.
Eu fiz meu dever de casa, li posts e experimentei muitos comandos, mas nenhum deles funcionou corretamente. Os seguintes comandos foram executados:
os sensores emitem 3 minutos de tempo de atividade
Adapter: Virtual device
temp1: +74.0°C (crit = +105.0°C)

Core 3: +74.0°C (high = +84.0°C, crit = +100.0°C)
Depois disso, eu corri um "dmesg", aqui está a saída

Core 3: +80.0°C (high = +84.0°C, crit = +100.0°C)
Outra saída "dmesg":
[ 993.126316] intel_powerclamp: Start idle injection to reduce power
De repente, o loadloadage sobe e eu tenho isso em "top":

Após alguns minutos, o carregamento da carga retorna ao normal e a temperatura cai um pouco, mas depois de 14 minutos a temperatura está alta novamente:

Depois disso, os processos kidle_inject retornaram e nunca foram embora:
load average: 5,79, 5,18, 3,12
Desde que o notebook começou a congelar, eu reiniciei no Windows, e para minha surpresa, após 2 ou 3 minutos de tempo de atividade, a saída "Core Temp" foi esta:
Captura de tela do Core Temp
O mesmo comportamento ocorre com os "drivers" OpenSource ou CPU proprietários.
Eu também tentei "rmmod intel_powerclamp", mas isso só impediu que o kidle_inject acontecesse novamente, a temperatura ainda permanece muito alta.
Qualquer ajuda é apreciada.
