Ubuntu菜单音频、视频制作、图形目录菜单条目消失

Question

Ubuntu菜单坏了--我一定安装了什么或者对菜单做了一些更改(我使用菜单编辑器添加了一个启动器)，我丢失了音频制作、视频制作和图形菜单条目。

以下是~/.local/share/desktop-directories中的文件列表：

-rw-rw-r-- 1 xxxxx xxxxx 204 Jul  6 07:59 ubuntustudio-audioproduction.directory
-rw-rw-r-- 1 xxxxx xxxxx 211 Jul  5 10:32 ubuntustudio-graphics.directory
-rw-rw-r-- 1 xxxxx xxxxx 204 Jul  5 10:32 ubuntustudio-videoproduction.directory

以下是~/.local/share/applications中的文件列表：

-rw-rw-r-- 1 xxxxx xxxxx 271 Jul  6 08:00 menulibre-new-launcher.desktop
-rw-rw-r-- 1 xxxxx xxxxx   0 Jun 22 14:35 mimeapps.list
-rw-rw-r-- 1 xxxxx xxxxx  14 Jul  6 07:57 mimeinfo.cache

我尝试通过将“隐藏菜单”按钮更改为on来编辑可见性，希望可以将其更改为off以重写配置文件，但不会从off中更改。

以下是~/.config/menus/xfce-applications.menu上文件的内容：

Answer 1

遗憾的是，Ubuntu目前附带的菜单编辑器中有一个已知的问题: MenuLibre。

当有人编辑Ubuntu菜单时，右击它就会打开MenuLibre编辑器，他得到的是一个完全错误的菜单。

尝试使用应用程序Alacarte来编辑菜单，而不是使用Menulibre。它应该修复它；它有一个按钮来恢复默认菜单。(如果在菜单中找不到Alacarte，只需在终端模拟器中运行命令alacarte即可。如果没有安装，请通过运行sudo apt-get install alacarte来安装)

对于那些想了解技术细节的人来说，这个已知的问题是当前确认的臭虫 For MenuLibre：

bug报告中给出了一个可能的解释：

看来menulibre使用的是系统菜单文件/etc/xdg/menus/xfce-applications.menu，而不是按会话指向的文件，即/etc/xdg/xdg-ubuntustudio/menus/xfce-applications.menu。这是会话运行的文件、whisker和应用程序菜单使用的文件。menulibre不使用这个。此外，menulibre自己制定了全新的菜单规范，而不是仅仅改变菜单的要求部分。这是不对的。我建议要么手工进行这些更改，要么使用alacart (alacart也有问题)，Ubuntustudio应该从其应用程序列表中删除menulibre。
