1.原来，是英特尔的集显
2.添加N卡驱动
1.检查是否有GPU显卡，我电脑一张集显，一张独显，很清楚。如果不清楚的可以用 lspci | grep -i nvidia查看：
linux2021@dahu:~$ lspci | grep -i nvidia 01:00.0 VGA compatible controller: NVIDIA Corporation GP106M [GeForce GTX 1060 Mobile] (rev a1) 01:00.1 Audio device: NVIDIA Corporation GP106 High Definition Audio Controller (rev a1) linux2021@dahu:~$
2.检测推荐的驱动ubuntu-drivers devices
linux2021@dahu:~$ ubuntu-drivers devices == /sys/devices/pci0000:00/0000:00:1c.0/0000:02:00.0 == modalias : pci:v00008086d000024FDsv00008086sd00009010bc02sc80i00 vendor : Intel Corporation model : Wireless 8265 / 8275 manual_install: True driver : backport-iwlwifi-dkms - distro free == /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0 == modalias : pci:v000010DEd00001C20sv00001D72sd00001706bc03sc00i00 vendor : NVIDIA Corporation model : GP106M [GeForce GTX 1060 Mobile] driver : nvidia-driver-460 - distro non-free driver : nvidia-driver-390 - distro non-free driver : nvidia-driver-450-server - distro non-free driver : nvidia-driver-460-server - distro non-free recommended driver : nvidia-driver-418-server - distro non-free driver : nvidia-driver-450 - distro non-free driver : xserver-xorg-video-nouveau - distro free builtin
3.安装驱动
(1)自动安装合适的版本
sudo ubuntu-drivers autoinstall
(2) 安装指定版本
如：
sudo apt-get install nvidia-driver-390
4.重启
安装成功
