Nvidia Corporation is an American technology company which specializes at designing graphics processing units (GPUs) for the gaming, cryptocurrency and a system on a chip unit (SoCs) for the mobile computing and automotive market. For those in possession of PC running Debian operating system and have Nvidia graphics card, you need to install the drivers for optimized hardware acceleration of OpenGL applications via a direct-rendering X server. This article I will show you how to install the latest version of NVIDIA driver using the Debian 9 repositories.
To identify your system NVIDIA GPU codename of the installed video card, use lspci command.
$ lspci | grep -E "VGA|3D" 01:00.0 3D controller: NVIDIA Corporation GK107M [GeForce GT 750M] (rev a1)
This will tell you whether you have Nvidia graphics card on your system.
Installing Nvidia Drivers
After identifying, we can now head to the installation section of graphics driver on Debian 9. Note that multiple precompiled driver versions are available for Debian 9 "Stretch". As of stretch Debian release, you don't need nvidia-xconfig anymore, and a xorg.conf file is not needed either in the most situation. Everything should just work out of the box.
Since the drivers are available on the "contrib" and "non-free" repository components. Add them to your /etc/apt/sources.list file.
$ sudo su - # echo "deb http://httpredir.debian.org/debian/ stretch main contrib non-free" >> /etc/apt/sources.list
Then update your cache index and do a system upgrade.
$ sudo apt-get update $ sudo apt-get upgrade && sudo apt-get dist-upgrade $ sudo reboot
After all above is successfully executed, install the appropriate linux-headers and kernel module packages:
$ sudo apt install linux-headers-$(uname -r|sed 's/[^-]*-[^-]*-//') nvidia-driver nvidia-kernel-dkms
This will install the nvidia-driver package. DKMS will build the nvidia module for your system, via the nvidia-kernel-dkms package.
For the nouveau Xorg display driver to be blacklisted, restart your system. Nvidia driver will be loaded fine after.
$ sudo reboot
Get Nvidia driver version
Use nvidia-smi command which reads temps directly from the GPU without the need to use X at all. For this, run:
$ sudo nvidia-smi
It will give you information about NVIDIA driver version. NVIDIA module should be properly loaded for this to work.
Get module version
If execution of the above command fails for any reason since NVIDIA module couldn't be loaded, you can always see NVIDIA version number by directly retrieving nvidia.ko module using the modinfo Linux command. The below command will check for NVIDIA driver version under your currently running kernel:
nbsp;modinfo /usr/lib/modules/$(uname -r)/kernel/drivers/video/nvidia.ko | grep ^version version: 390.77
Creating empty xorg.conf
For systems, you may need to remove xorg.conf file to Nvidia to work properly. Use the commands below for this.
$ sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf.old $ sudo touch /etc/X11/xorg.conf
And reboot the system.
Manually creating xorg.conf
If you need to modify your xorg.conf for Nvidia driver, a sample configuration is provided below.
~$ cat /etc/X11/xorg.conf Section "ServerLayout" Identifier "Layout0" Screen 0 "Screen0" InputDevice "Keyboard0" "CoreKeyboard" InputDevice "Mouse0" "CorePointer" EndSection Section "Files" EndSection Section "InputDevice" # generated from default Identifier "Mouse0" Driver "mouse" Option "Protocol" "auto" Option "Device" "/dev/psaux" Option "Emulate3Buttons" "no" Option "ZAxisMapping" "4 5" EndSection Section "InputDevice" # generated from default Identifier "Keyboard0" Driver "kbd" EndSection Section "Monitor" Identifier "Monitor0" VendorName "Unknown" ModelName "Unknown" HorizSync 30.0 - 80.0 VertRefresh 55.0 - 75.0 DisplaySize 400 225 Modeline "1920x1080_60.00" 172.80 1920 2040 2248 2576 1080 1081 1084 1118 -HSync +Vsync Option "DPMS" EndSection Section "Device" Identifier "Device0" BusID "PCI:1:0:0" Driver "nvidia" VendorName "NVIDIA Corporation" EndSection Section "Screen" Identifier "Screen0" Device "Device0" Monitor "Monitor0" DefaultDepth 24 SubSection "Display" Viewport 0 0 Depth 24 Modes "1920x1080_60.00" EndSubSection EndSection
The configuration shown is for a 1920x1080 resolution. Key things to note.
- Specify the correct HorizSync and VertRefresh
You can generate Modeline using:
nbsp;gtf 1920 1080 60
Then add name Modeline in Modes. Restart Xorg server after changing it. A reboot of the system may be necessary as well.
