# NVIDIA Driver Install
###### tags: `NV-Driver`

0. 安裝```dkms```

    sudo apt install -y dkms

2. Disable 開源驅動(nouveau)

    # Create a file at /usr/lib/modprobe.d/blacklist-nouveau.conf with the following contents:
    sudo bash -c "echo blacklist nouveau > /etc/modprobe.d/blacklist-nvidia-nouveau.conf"
    sudo bash -c "echo options nouveau modeset=0 >> /etc/modprobe.d/blacklist-nvidia-nouveau.conf"
    # Regenerate the kernel initramfs:
    sudo update-initramfs -u

然後請重新開機。
2. 進入終端機模式(關閉```lightdm```)

    # Supposing you have `lightdm` as the desktop manager
    sudo systemctl stop lightdm
    
    # if you don't have lightdm, simply execute:
    # sudo init 3

3. 下載 & 安裝driver

    # Download the NV driver
    runfile="NVIDIA-Linux-x86_64-430.50.run"
    runfile_url="http://us.download.nvidia.com/XFree86/Linux-x86_64/430.50/${runfile_name}"
    wget -O $runfile $runfile_url
    
    # Install the NV driver
    sudo bash $runfile -a --silent --no-opengl-files --dkms

4. 打開```lightdm```，恢復桌面模式

    sudo systemctl start lightdm

5. 於終端機輸入```nvidia-smi```, 看是否有正常顯示GPU的資訊，例如:
