多显示器按名称组织桌面错误

多显示器按名称组织桌面错误

我正在使用带有 Unity 的 Ubuntu 14.04LTS，并使用两个显示器：我的笔记本电脑内置显示器，1366x768 和外接显示器，分辨率为 1920x1080。

我的主显示器是内置的，因此，当我右键单击桌面并“按名称组织桌面”时，图标就会进入该桌面并对齐。

当我有许多图标需要对齐时就会出现问题，Unity 会将一些图标发送到我可见的屏幕下方，可能是考虑到更大的显示器分辨率。

我测试选择所有对齐的图标（ctrl+a）并拖到更大的显示器，但似乎隐藏的图标也相互重叠。

不管怎样，这似乎是一个错误，对吗？

我还没有检查 14.10 来查看这个问题是否已经修复。

谢谢

答案1

是的，我遇到了同样的问题..我单击“按名称组织桌面”，然后图标消失，我必须按 ctrl-A 才能将它们重新带回视图。

答案2

我写了一个脚本来更新图标的位置。无论你的屏幕分辨率是多少，这个脚本都可以使图标适合屏幕。

它很慢，在我的计算机上处​​理 100 个文件需要 1 秒多一点的时间。但至少它能工作。不过，也许有更好的方法来实现这一点……

将以下代码复制并粘贴到名为“arrange_icons.sh”的文件中。在终端中运行chmod 755 /path/to/arrange_icons.sh。使用以下命令运行脚本/path/to/arrange_icons.sh

#!/bin/bash

在我的计算机上，我设置了一个 crontab，每秒检查一次桌面文件夹。如果有任何变化，则运行上述脚本。
