The first 1 Methods :. The best way is not to manually install the official driver ( Manual installation of official driver is not available gpu, And it can't be enabled 3d, It doesn't work at the same time , So it's best to use this method ), But use bumblebee-nvidia install , But first add x-swat Source .

  1. sudo vi /etc/modprobe.d/blacklist.conf

Add a row  
blacklist nouveau

2. Uninstall the official driver nouveau

sudo apt-get –purge remove xserver-xorg-video-nouveau

sudo reboot
sudo apt-get install bumblebee-nvidia bumblebee virtualgl 
Pay attention to the need for update-grub And then restart it to take effect ,( modify grub It's the same after the configuration file update-grub, Otherwise, the brightness cannot be adjusted normally )

The second way ( Not recommended , I failed many experiments ,)
