Update the graphics card driver

Update the video card driver-Debian information of the Linux release version. For more information, see the following section. By default, only a few programs and libraries are configured for Debian installation. Therefore, you must download the required libraries for driver installation.
Desktop → System Management → New Software Package Manager → refresh → search → enter "linux-header"
In the filtered package, select the package corresponding to your kernel → application.

If X is enabled, the driver cannot be installed.
Therefore, we need to enter the plain text interface, so we will not let X start
Su
Gedit/etc/inittab
Change id: 2: initdefault: to id: 1: initdefault:
Save and exit
Restart
This will not automatically start X, but automatically enter the text interface.
Run the downloaded driver using the sh command.
For example, the path of your driver is as follows:
/Home/alin/Desktop/NVIDIA-Linux-x86_64-1.0-9746-pkg2.run
Then execute
Sh/home/alin/Desktop/NVIDIA-Linux-x86_64-1.0-9746-pkg2.run

In this way, the graphics card driver is installed.

Vim/etc/inittab
Change id: 1: initdefault: to id: 2: initdefault:
Restart and switch back to x.
If the NVIDIA image is displayed, the driver is successfully installed.

Delete the NVIDIA graph when X is started.
Enter
Su
Gedit/etc/X11/xorg. conf
In the Device section, find "nvidia" and add Option "NoLogo" to the end of the same line"
Save and exit
