未检测到风扇

我正在尝试在笔记本电脑上使用 ubuntu。但风扇似乎不工作。我尝试使用 sudo pwmconfig，但结果如下。

sudo pwmconfig
# pwmconfig revision 6166 (2013-05-01)
This program will search your sensors for pulse width modulation (pwm)
controls, and test each one to see if it controls a fan on
your motherboard. Note that many motherboards do not have pwm
circuitry installed, even if your sensor chip supports pwm.

We will attempt to briefly stop each fan using the pwm controls.
The program will attempt to restore each fan to full speed
after testing. However, it is ** very important ** that you
physically verify that the fans have been to full speed
after the program has completed.

/usr/sbin/pwmconfig: There are no fan-capable sensor modules installed

我也尝试了〜$ lspci -k | grep -EA2'VGA | 3D'，结果是这样的

00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09)    Subsystem: ASUSTeK Computer Inc. Device 1477
    Kernel driver in use: i915
01:00.0 VGA compatible controller: NVIDIA Corporation GF108M [GeForce GT 635M] (rev a1)     Subsystem: ASUSTeK Computer Inc. Device 1477
    Kernel driver in use: nouveau

我的笔记本电脑温度很高，我该怎么做才能解决这个问题？

答案1

您的系统中有两个图形适配器。现在它们都已启用并消耗电量。

此外，该nouveau驱动器的动力也不佳。

您需要安装专有驱动程序。在终端中运行：

sudo apt-get install nvidia-352 nvidia-prime

然后重新启动。

你可以通过以下方式切换到集成适配器，从而节省更多电量并使计算机更凉爽：

sudo prime-select intel

或者使用 GUI。
