ubuntu中的nvidia，已安裝但未考慮

我的華碩筆記型電腦裡有GP108BM [GeForce MX250]。我從“附加驅動程式”安裝了驅動程式並運行了幾個命令。

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

然而：

你可以在 中看到configuration driver=i915 latency=0。在關於/設定中：

我的計劃是主要將它用於 fastai 和 pytorch (AI)，但也用於其他任何東西。據我了解，驅動程式已安裝，但係統未將 nvidia GPU 視為主要GPU。非常感謝任何幫助。

步驟如下：

解除安裝 NVIDIA 驅動程式

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

禁用安全啟動。

重新安裝驅動程式

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