| # Nvidia drivers for optimus GPU; | |
| How to install Nvidia drivers and configure bumblebee on Ubuntu 16.04 with optimus GPU. | |
| It doesn't work with Ubuntu 18+ (I recommend manual switch between GPU in this case). | |
| Tested on Ubuntu 16.04 with Geforce GT 750m and Intel HD graphic | |
| _______________________________________________________________________________________________________________ | |
| - Step 1: remove all video drivers; | |
| sudo apt-get remove --purge nvidia* bumblebee* xserver-xorg-video-nouveau | |
| - Step 2: be sure to have all the headers; | |
| sudo apt-get install linux-source && sudo apt-get install linux-headers-$(uname -r) | |
| - Step 3: blacklist "nouveau" and "nvidia-current" | |
| in "/etc/modprobe.d/blacklist.conf" add the following lines at the end of the file: | |
| blacklist nouveau | |
| blacklist lbm-nouveau | |
| blacklist nvidia-173 | |
| blacklist nvidia-96 | |
| blacklist nvidia-current | |
| blacklist nvidia-173-updates | |
| blacklist nvidia-96-updates | |
| alias nvidia nvidia_current_updates | |
| alias nouveau off | |
| alias lbm-nouveau off | |
| options nouveau modeset=0 | |
| - Step 4: run "update" and stop the X server; | |
| sudo apt-get update && sudo apt-get dist-upgrade -y | |
| sudo service lightdm stop | |
| open tty1 console with "ctrl+alt+F1" | |
| - Step 5: install nvidia drivers and Bumblebee | |
| sudo apt-get install nvidia-384 | |
| check the driver for your gpu on the nvidia site. I installed "nvidia-384" for my Geforce GT 750m. | |
| reboot with: | |
| sudo reboot | |
| install Bumblebee: | |
| sudo add-apt-repository ppa:bumblebee/testing | |
| sudo apt update | |
| sudo apt install bumblebee | |
| install primus: | |
| sudo apt-get install primus | |
| - Step 6: Change bumblebee configuration; | |
| sudo nano /etc/bumblebee/bumblebee.conf | |
| Change line 22 "Driver=" to "Driver=nvidia" | |
| Change line 55 "KernelDriver=nvidia-384" # or whatever your current nvidia driver is | |
| Change line 58 to "LibraryPath=/usr/lib/nvidia-384-updates:/usr/lib32/nvidia-381-updates" #or whatever your current nvidia driver is | |
| Change line 61 to "XorgModulePath=/usr/lib/nvidia-384-updates/xorg,/usr/lib/xorg/modules" #or whatever your current nvidia driver is | |
| Than check that your "BUSID" in /etc/bumblebee/xorg.conf.nvidia is uncommented (without "#" at the beginning of the line) | |
| 1) Check if nvidia prime is set on "intel mode". If it is in nvidia mode switch gpu; | |
| 2) If the prime icon says "Current graphics card: Unknown" after installing primus is because you need to update your system. In this case, select "Install Updates" clicking of the prime icon on the panel. If you get "Current graphics card: Unknown" without an update warning you should probably switch to a newer nvidia driver; | |
| 3) To run applications using your nvidia GPU use "optirun 'application'" or "primusrun 'application'". | |
| # Screen tearing fix | |
| Create a file named 20-intel.conf and put this inside: | |
| Section "Device" | |
| Identifier "Intel Graphics" | |
| Driver "intel" | |
| Option "TearFree" "true" | |
| EndSection | |
| Place the file in "/etc/X11/xorg.conf.d" with: | |
| sudo cp -R 20-intel.conf /etc/X11/xorg.conf.d | |
| and reboot. | |
| Enjoy! |
