我刚从公司买了一台新笔记本电脑，但无法设置双屏。它不是双启动，所以我无法在 Windows 上测试它是否可行。
实际上我的笔记本电脑可以识别第二个屏幕，但是屏幕是黑色的，我只可以在第二个屏幕上看到我的鼠标。每个窗口都可以进入第二个屏幕，我可以与它们交互，但屏幕是全黑的。
我尝试使用 nvidia 驱动程序 435 和 440 进行不同的选择，但在这种情况下，我只能与第二个屏幕交互，而不是笔记本电脑上的屏幕。这是我的所有测试和结果：
- 没有 Nvidia 驱动程序：双屏识别，但第二个屏幕是黑色的，但我可以交互
- 使用 Nvidia 驱动程序 440（计算机推荐）：我只能与我的第二个屏幕交互，而笔记本电脑上的屏幕完全空白
- 使用 Nvidia 驱动程序 435：没有图形界面。
这是我的 xrandr 和我的电视第二屏幕（我在家）：
