Linux Mint 17.2 Rafaela 中的双显示器设置

2024-5-27 • tag-icon

好吧，我现在已经全力解决这个问题 6 天了（之前的尝试已经超过两周了）。

我的问题是设置 Linux Mint，并将外部显示器插入我的笔记本电脑。

我已经尝试了网上能找到的所有建议，但都没有成功。现在我准备因为尝试和失败而损坏我的笔记本电脑！

我的系统和硬件

我已经尝试过了

多次编辑 /etc/X11/xorg.conf，有时 X 无法启动，所以我不得不从 tty 终端撤消更改并重新启动。这是我当前的 xorg.conf：

我已将以下 .conf 文件添加到 /usr/share/X11/xorg.conf.d：

41-built-in-monitor.conf 其中包含：

        VendorName   "Built in Monitor"
        ModelName    "Model Unknown"
        HorizSync       28.0 - 70.0
        VertRefresh     56.0 - 75.0
    EndSection

42-second-vga-monitor.conf 其中包含：

    Section "Monitor"
        Identifier   "Monitor1"
        VendorName   "ViewSonic"

        VertRefresh     56.0 - 75.0
    Endsection

50-video.conf 其中包含：

    Section "Device"
        Identifier "Device2"
        Option  "Monitor-Built-In" "Monitor0"
        Option  "Monitor-VGA"      "Monitor1"

我发现了更多建议，事实上我已经尝试过很多事情，即使我记得，我也无法在这里列出它们！

Mate Monitor Preferences 无法识别外部显示器（显然）。

Arandr 的行为就好像我只有“默认”监视器一样。

我的系统在两个屏幕上都显示，但是不是单独地，就像两台显示器上的一样，所以显示器可以工作，VGA 适配器也可以工作，显卡可以输出到两者，只是不是一个正确的双显示器设置。

如果有人知道 ~/.config/monitors.xml 到底是做什么用的？
