不在底座上时自动更改分辨率

我的联想 W520 上装有 Ubuntu 11.04（是的，我知道这已经是旧闻了）。在家里，我有一个带双显示器的底座。我的设置相当不错 - 一切运行得几乎完美（这就是我不愿意升级的原因......因为我对 Unity 并不是 100% 的忠实拥护者）。

无论如何，我唯一感到烦恼的是，当我在旅行时，我会使用笔记本电脑的屏幕。当我将笔记本电脑从底座上取下时，我需要手动进入 nvidia x-server 设置并将分辨率从“自动”更改为 1920x1200，否则它会认为我有两个屏幕，并且我的鼠标指针将能够远离屏幕的左侧。这不是什么大问题，但我需要这样做每一个我重新启动 x 服务器（因此如果我重新启动，或者必须终止它，等等...）

如果有一种方法可以自动检测是否有外接显示器（它似乎已经这样做了），并根据连接的显示器切换到我选择的模式，那就太好了。有什么方法可以做到这一点吗？我已发布我的 xorg.conf 文件以供参考。

hwinfo如果您还没有，请安装。

现在，跑，$hwinfo --monitor或者只是$hwinfo

现在不要将其连接到基座。重新启动，选择您喜欢的分辨率并运行

$ sudo cp /etc/X11/xorg.conf /etc/X11/xorg.undock

现在将系统对接，然后重新启动。选择您最喜欢的新分辨率并运行

$ sudo cp /etc/X11/xorg.conf /etc/X11/xorg.dock

创建一个脚本文件并将其添加到自动运行：

    # Check if system is docked or undocked and use correct xorg.conf file.
    # <lm_name> is name of laptop monitor
    DOCKED="`hwinfo --monitor | grep "<lm_name>" | wc -l`" 
    # Next line is for debugging
    # echo $DOCKED > /root/docked-state.txt 
    if [[ $DOCKED = "0" ]] 
    then 
    cp /etc/X11/xorg.dock /etc/X11/xorg.conf 
    else 
    cp /etc/X11/xorg.undock /etc/X11/xorg.conf 
    fi 
    # End of dock-undock script

有一些工具可以自动在显示器之间切换。你可以使用这些工具来自动化 RandR、disper、displex 或这个http://gnomefiles.org/content/show.php/Laptop+external+display+hotplugging?content=138742
