Ubuntu 19.04风扇始终打开,我的笔记本电脑比在Windows上温暖

我一个月前已将笔记本电脑升级到ubuntu 19.04。现在,我的笔记本电脑风扇几乎始终处于打开状态(低速运行),并且在运行Windows10时,笔记本电脑比笔记本电脑更热。同样,处于完全充电模式的电池在Windows上可工作约5个小时,在ubuntu上可工作约3个小时。

I checked my Nvidia tool and saw that I am using intel as my graphical processor. I get below message when run nvidia-smi lms:

NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.

When I was on ubuntu 16.04 I could install bumblebee but now I check that it is not useful for newer versions of Ubuntu to install it. What should I do or install to have the same performance as in the windows?
