ubuntu 中的 nvidia,已安装但未考虑

我的华硕笔记本电脑上有这个GP108BM [GeForce MX250]。我从“附加驱动程序”安装了驱动程序并运行了几个命令。

sudo prime-select nvidia
Info: the nvidia profile is already set

然而:

您可以在 中看到configuration driver=i915 latency=0。在 about/settings 中:

我的计划是主要将其用于 fastai 和 pytorch (AI),但也可用于其他任何用途。据我了解,驱动程序已安装,但系统未将 nvidia GPU 识别为主要 GPU。任何帮助都将不胜感激。

遵循的步骤:

卸载 NVIDIA 驱动程序

sudo apt-get remove --purge '^nvidia-.*'
sudo apt-get install ubuntu-desktop
sudo apt-get --purge remove "*cublas*" "cuda*"
sudo apt-get --purge remove "*nvidia*"
sudo add-apt-repository --remove ppa:graphics-drivers/ppa
sudo rm /etc/X11/xorg.conf
sudo apt autoremove
sudo reboot

禁用安全启动。

重新安装驱动程序

sudo ubuntu-drivers devices
sudo ubuntu-drivers autoinstall
sudo reboot
