我有一台戴尔 XPS 15 型号的电脑，刚刚安装了全新的 Ubuntu 22.04.1 LTS。一开始安装时遇到了很多问题，但过了一段时间后就成功了。我还尝试安装“nvidia-drivers-515”驱动程序。我也遇到了一些问题，但最终还是安装成功了。
Ubuntu 似乎仍在使用集成卡，而不是 Nvidia。
这是一些输出。
➜ ~ lspci -nn | grep -E 'VGA|Display'

系统可以识别这两张卡，但使用的是集成卡。

从以下输出来看 Nvidia 似乎处于休眠状态或者我遗漏了什么？

为什么两张卡都处于活动状态？如何确保我正在使用 Nvidia 并且驱动程序正常运行？
