0a:00.1 Audio device: NVIDIA Corporation Device 1aef (rev a1)

2，驱动安装

wget https://us.download.nvidia.com/XFree86/Linux-x86_64/455.23.04/NVIDIA-Linux-x86_64-455.23.04.run

# echo $TMPDIR
/tmp

• 安装驱动

bash NVIDIA-Linux-x86_64-455.23.04.run

3，禁用nouveau

# lsmod | grep nouveau
nouveau              1708032  0
mxm_wmi                16384  1 nouveau
video                  45056  2 asus_wmi,nouveau
i2c_algo_bit           16384  1 nouveau
ttm                   106496  1 nouveau
drm_kms_helper        172032  2 nvidia_drm,nouveau
drm                   401408  5 drm_kms_helper,nvidia_drm,ttm,nouveau
wmi                    24576  4 asus_wmi,wmi_bmof,mxm_wmi,nouveau

• vim /etc/modprobe.d/blacklist.conf
  添加

blacklist nouveau

# update-initramfs -u
update-initramfs: Generating /boot/initrd.img-4.15.0-118-generic
I: The initramfs will attempt to resume from /dev/nvme1n1p3
I: (UUID=204fe6d9-3a1d-4e1c-8110-bca0a46fd38e)
I: Set the RESUME variable to override this.

echo "blacklist nouveau" >> /etc/modprobe.d/blacklist.conf

reboot

4，卸载显卡驱动重新安装

dpkg -l | grep -i nvidia

apt purge nvidia* -y

bash NVIDIA-Linux-x86_64-455.23.04.run

5，卸载nvidia cuda驱动

apt-get --purge remove nvidia*

apt-get --purge remove "*nvidia*"

apt-get --purge remove "*cublas*" "cuda*"

安装驱动 ubuntu-drivers
