![在基于 AMD 的机器上安装双启动 Ubuntu 20.04 而不使用 Nvidia 驱动程序](https://linux22.com/image/1025188/%E5%9C%A8%E5%9F%BA%E4%BA%8E%20AMD%20%E7%9A%84%E6%9C%BA%E5%99%A8%E4%B8%8A%E5%AE%89%E8%A3%85%E5%8F%8C%E5%90%AF%E5%8A%A8%20Ubuntu%2020.04%20%E8%80%8C%E4%B8%8D%E4%BD%BF%E7%94%A8%20Nvidia%20%E9%A9%B1%E5%8A%A8%E7%A8%8B%E5%BA%8F.png)
我最近购买了一台安装了 Windows 10 家庭版的联想 Legion 5 15ACH6 笔记本电脑。它的 CPU 是 AMD Ryzen 7 5800H,集成 Radeon 显卡,系统内存为 16 GB,GPU 是 Nvidia GeForce RTX 3050(视频内存:4 GB,GDDR6)。在 BIOS 菜单中,我已禁用安全启动选项,并将图形设备设置为默认选项“动态图形”(其他可用选项是“独立显卡”)。我使用 GNU GRUB 菜单中提供的“安全图形”选项在系统上双启动安装了 Ubuntu 20.04。我成功安装了 Ubuntu,但它没有使用 Nvidia 显卡,而是使用了集成的 Radeon 显卡。我尝试在线寻找问题的解决方案,但找不到具体的答案。我对如何继续纠正这个问题有点困惑,希望得到一些帮助。以下是我根据网上的信息尝试的一些命令:
$ dkms status
$
从上述命令未观察到任何输出。
$ 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.
$ nvidia-settings; lspi -V | grep VGA
ERROR: NVIDIA driver is not loaded
ERROR: Unable to load info from any available system

** Message: 14:19:56.988: PRIME: No offloading required. Abort
** Message: 14:19:56.988: PRIME: is it supported? no
上述命令还会打开一个名为“NVIDIA X 服务器设置”的空白对话框
