lenovo ideapad 320启动时有时黑屏

我的 Lenovo IdeaPad 320 i5 第 8 代遇到问题，每当我想通过Hibernate按下电源按钮启动它时，有时会显示黑屏。有时它工作得很好，但当多次尝试后仍不显示屏幕时，这非常烦人。

nvidia-smi显示错误：

azizul@deapad:~$ nvidia-smi
NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.

没有列出其他驱动程序：

GPU 基准测试：

azizul@deapad:~$ glxgears
310 frames in 5.0 seconds = 61.860 FPS
301 frames in 5.0 seconds = 60.012 FPS
301 frames in 5.0 seconds = 60.020 FPS
301 frames in 5.0 seconds = 60.007 FPS
301 frames in 5.0 seconds = 60.013 FPS
301 frames in 5.0 seconds = 60.014 FPS
301 frames in 5.0 seconds = 60.014 FPS

答案1

您没有 Nvidia 显卡的驱动程序。

打开终端并写入以下命令：

sudo add-apt-repository ppa:graphics-drivers/ppa && sudo apt update

然后您将能够通过其他驱动程序安装驱动程序。您也可以直接使用以下命令安装：

sudo apt-get install nvidia-driver-410

最好dkms先安装驱动程序，因为每当系统内核更新时，dkms都会自动为新内核重建 NVIDIA 驱动模块：

sudo apt-get install dkms build-essential

您没有提到您的 Nvidia 显卡型号，但我认为它是 GeForce MX150，并且在受支持的显卡列表中。
