我可以毫无问题地调整与 xrandr 连接的任何外部显示器的设置。但是，使用 xrandr 更改任何设置后，我的主笔记本电脑屏幕将变黑。启动进入恢复终端后，我在运行时遇到“无法打开显示”xrandr -q
我的笔记本电脑的原始分辨率是 3840x2160 60hz，我尝试使用支持的模式或使用--scale 0.5x0.5
该笔记本电脑是一台 Lenovo X1 Extreme，运行带有 nouveau 驱动程序的 Void Linux。

eDP-1 是我的本机笔记本电脑显示器，HDMI-1 是外部显示器。目前，如果我在断开外部显示器的情况下启动，笔记本电脑将启动进入黑屏，并出现“无法打开显示器”问题。在连接外部显示器的情况下启动时，笔记本电脑屏幕仍然变黑，但显示器按预期工作。
谢谢。
