应用程序未出现在Dash中（14.04）

我正在运行14.04

应用程序破折号

我已经通读了这个问题，该问题的答案大致与网络上的其他答案类似，对我不起作用。

所有应用程序都消失在破折号中

我可以毫无问题地搜索所有其他文件，但是当我尝试搜索“应用程序”时却无法执行。

我不确定在哪里进行故障排除-我已经确保将unity-lens-applications其与一起安装unity-scope-master。

我还有什么可以解决的吗？老实说，我宁愿不必从终端启动我的所有应用程序。

在新创建的用户帐户上，确实会出现应用程序。但是，我想在登录时解决此问题。

建议的修复

unity在alt + F2中运行
这将返回与上面相同的错误，但要减去过滤器。
sudo apt-get install zeitgeist zeitgeist-core
它已经安装并且是最新的

由于它仅受限于您的用户帐户，因此它必须与您的用户有关。

也许.desktop您的主文件夹中的文件之一正在使启动器跳闸？您可以尝试将这些文件夹中的文件移动到其他位置吗？

/home/<youruser>/.gnome/apps/
/home/<youruser>/.local/usr/share/applications/

例如

$ mkdir backup_local
$ mkdir backup_gnome
$ mv .local/share/applications/*.desktop backup_local/
$ mv .gnome/apps/*.desktop backup_gnome/

然后注销，登录并查看是否有任何更改？如果无济于事，您可以随时将它们移回原处。如果确实有帮助，请尝试将它们一一移动到罪魁祸首。

编辑：您可以找出哪一个格式错误：

安装desktop-file-utils软件包：

sudo apt-get install desktop-file-utils

使用以下命令检查每个.desktop文件的有效性desktop-file-validate：
```
desktop-file-validate .local/share/applications/*.desktop
desktop-file-validate .gnome/apps/*.desktop
```
或者，如果您已经移动了它，当然也可以在其他位置。如果所有文件都正常，它将不打印任何内容。如果任何文件格式错误，它将每行打印一条错误消息。

您可能还需要检查其他桌面文件以取得良好的效果：
```
desktop-file-validate /usr/share/applications/*.desktop
```
