我在 rog zephyrus g14 上安装了 Ubuntu 20.04，当我尝试打开 nvidia x 服务器设置时，它只显示空白窗口。我也尝试运行，nvidia-smi但它只返回此信息：NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.我已检查是否在附加驱动程序管理器中选择了专有驱动程序，并且nvidia-driver-440已选中。任何帮助都非常感谢。
