我正在运行 NVIDIA 驱动程序515.65.01和 Kubuntu 22.10。我想将我的计算机设置为仅使用集成 GPU，因为按需模式仍允许 Xorg 在其上运行。但是，这样做的设置是灰色的。我该如何解决这个问题，或者，如果失败了，通过其他方法来实现这一点？
答案1
免责声明：这仅适用于 Ubuntu 和 Ubuntu 版本
可以通过手动启用 Intel 专用模式sudo prime-select intel，然后执行系统重启。Intel 专用模式仍为灰色，但已被选中。
我很确定它确实有效，因为nvidia-smi返回以下消息：
NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.
