Ubuntu安装NVIDIA显卡驱动

清理旧驱动

sudo apt purge nvidia* libnvidia* sudo apt autoremovesudo find /etc -name \'*nvidia*\' -exec sudo rm -rf {} +sudo rm -rf /usr/local/cuda*

禁用 nouveau

echo \'blacklist nouveauoptions nouveau modeset=0\' | sudo tee /etc/modprobe.d/blacklist-nouveau.confsudo update-initramfs -u

添加 PPA 并安装 open 驱动

注意：nvidia-driver-570-open 我的电脑是RTX 5070显卡，这里要安装对应显卡的驱动

sudo add-apt-repository ppa:graphics-drivers/ppasudo apt updatesudo apt install nvidia-driver-570-open

设置内核参数

sudo sed -i \'s/GRUB_CMDLINE_LINUX_DEFAULT=\"\\(.*\\)\"/GRUB_CMDLINE_LINUX_DEFAULT=\"\\1 nvidia-drm.modeset=1 nouveau.modeset=0\"/\' /etc/default/grubsudo update-grub

重启

sudo reboot

验证

登录后运行 nvidia-smi，确认 GPU 被识别。

成功
