在我的笔记本电脑 [Asus tuf F15] 中，它有 RTX3050，当我尝试使用 HDMI 输出的外接显示器时，外接显示器中没有显示信号，尽管我可以看到它设置 > 显示。它在 Windows 上运行良好。它适用于 ubuntu，但随后显示此错误
这是 xrandr 输出
xrandr -q

它使用手动安装的 nvidia 驱动程序
答案1
我尝试切换到 nvidia x 服务器，但之后它无法识别内部显示器
然后我尝试了解决方案 使用 nVidia X 服务器设置关闭内置显示器， 使用
sudo systemctl restart display-manager.service
完成了工作
