![Ubuntu 20.04 未检测到笔记本内置显示器](https://linux22.com/image/935854/Ubuntu%2020.04%20%E6%9C%AA%E6%A3%80%E6%B5%8B%E5%88%B0%E7%AC%94%E8%AE%B0%E6%9C%AC%E5%86%85%E7%BD%AE%E6%98%BE%E7%A4%BA%E5%99%A8.png)
使用 Ubuntu 20.4 无法检测到我的笔记本的内部显示器。两个外接显示器工作正常。但是,内部显示器根本不起作用。
我有一台配备 NVIDIA 显卡的 Tuxedo XP1610。以下是有关系统的一些信息。如果您需要更多信息来分析问题,请告诉我。我如何才能知道/测试为什么笔记本电脑的内部显示器无法检测到/工作。
提前致谢。
