Ubuntu Server 24.04 安装 英伟达RTX2070 Super显卡驱动

确认显卡型号​​

lspci | grep -i nvidia

更新系统​​（避免内核冲突）

sudo apt update && sudo apt upgrade -y

禁用开源驱动 Nouveau

Nouveau 是 Ubuntu 默认的开源驱动，与官方驱动冲突，必须禁用

sudo bash -c "echo 'blacklist nouveau' >> /etc/modprobe.d/blacklist-nouveau.conf"
sudo bash -c "echo 'options nouveau modeset=0' >> /etc/modprobe.d/blacklist-nouveau.conf"
sudo update-initramfs -u
sudo reboot

重启后验证是否禁用成功

lsmod | grep nouveau  # 若无输出则禁用成功

通过官方仓库安装驱动

添加显卡驱动 PPA 并查询推荐版本

sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt update
ubuntu-drivers devices  # 查看推荐版本（如 nvidia-driver-550）

安装推荐驱动

sudo apt install nvidia-driver-550  # 根据实际推荐版本调整
sudo reboot

验证安装

nvidia-smi

成功输出
