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，因为按需模式仍然允许 Xorg 在其上运行。但是，执行此操作的设置呈灰色。我该如何解决这个问题，或者如果无法解决这个问题，可以通过其他方法来完成此任务？

Answer 1

免责声明：这只适用于 Ubuntu 和 Ubuntu 版本

sudo prime-select intel可以通过然后执行系统重新引导来手动启用仅 Intel 模式。仅英特尔模式保持灰色，但已选中。

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.
