forget it if ur lap is running well. 

Beleive me,Installing graphic driver is horrible！

Idk, I always put them without problems in Ubuntu🥲 besides, without a NVIDIA video card, I cannot use some programs. So, maybe there is some way?

Just run in terminal:

sudo apt install nvidia-driver nvidia-smi nvidia-settings

and the latest nvidia driver will be installed.

If you need nvidia-prime, you can try Deepin Graphics Driver Manager, the latest version provides this option.

Or you can try this deb: https://github.com/zty199/dde-dock-switch_graphics_card/releases/download/v1.8.3/dde-dock-graphics-plugin_1.8.3_amd64.deb

After installation, you need to logout or reboot and let dde-dock load this plugin. If you need nvidia-prime, you need to switch to NVIDIA first and then switch back to Intel again, then nvidia-prime mode is enabled.

Ah, getting an error, i dont know how to fix that. Or its okay and i can ignore that?

O también puede usar este comando

#Lo primero que debemos hacer antes de instalar Nvidia, es instalar el neofetch

1 sudo apt-get update

2 sudo apt-get update && sudo apt-get neofecth

#Ya teniendo eso, vemos las configuraciones y comenzamos

3 sudo apt-get install nvidia-detect

#Veremos cual instalaremos 

4 nvidia-detect

#Al momento de saber cual versión comenzamos con esta

5 sudo apt install nvidia-driver

Oh, getting an error on "sudo apt-get install nvidia-detect"

That's weird...... I didn't met this issue. You can't just ignore that, because nvidia-driver is  NOT installed properly.....

First run "sudo apt autopurge nvidia-driver" to uninstall the half-configured nvidia-driver. Then check that if you have installed linux-headers-5.10.50-amd64-desktop. And run "sudo apt reinstall nvidia-driver" to try to install nvidia-driver again......There shouldn't be any error......

Still getting an errors after your advise..:(

Well, I would suggest you instialling .run file directly from Nvidia, but it reqiures a good knowledge of Linux to write xorg.conf and modify lightdm configuration.

Apart from that, you can use the instruction given in Nvidia CUDA page which can install both driver and CUDA correctly. However, it seems lack in i386 support so that you might run into problem with 32-bit program (like Steam).

Well, that I can't fix...... nvidia-driver 460.73 should work with linux-image 5.10.50, I don't know what happened......

Maybe you should paste your device info here and see if anyone can help you...... Just turn on Deepin Device Manager, right click and choose "Export" in context menu, and paste the info here.
