在 18.04 上没有镜像显示的选项 - DELL M3800

  • 772

我找不到在 Ubuntu 18.04 上镜像我的显示器的选项：

我在带有混合显卡的戴尔 M3800 上运行 Ubuntu。

在此处输入图像描述

什么可能导致这种情况？

的结果sudo lshw -c display

从 Live USB 启动时，这些选项也不可用。

切换到 NVIDIA 驱动程序340.107并nvidia-340没有解决它。

  1. 在 18.04 和 19.04 上的另一个非常快速的解决方案是使用键盘快捷键：[Windows 键 + p]，然后循环通过以获得正确的配置。

    从这个答案：如何在 3 显示器设置中镜像其中一个屏幕？尝试使用：

    xrandr --output eDP-1-1 --output HDMI-1-2 --output HDMI-1-2 --same-as HDMI-1-1

    在上面接受的解决方案中，屏幕 3 被镜像到屏幕 2，但主屏幕没有被镜像。

    另一个选择是切换到 Unity 桌面：Ubuntu 18.04 中的 GNOME 和多显示器设置

    单击按钮旁边的齿轮图标Sign In，如下所示：

    Ubuntu 5 DE.png

    注意：全新 18.04 安装可能需要安装 Unity Desktop。16.04 升级可能会默认使用 Unity。请参阅：如何让 Ubuntu 18.04 / 18.10 桌面使用 Unity（就像 Ubuntu 14.04）？
