我的应用程序在 Ubuntu 22.04 的“显示应用程序”屏幕中不可见

我的应用程序在 Ubuntu 22.04 的“显示应用程序”屏幕中不可见

您可以从屏幕截图中看到我安装了许多应用程序(Chrome、Steam、TeamViewer 等),但它们没有显示在我的“显示应用程序”屏幕上。事实上,它甚至没有显示 LibreOffice、Rhythmbox、游戏或其他应用程序。但是当我搜索它们的名字时,它们就会出现,我可以正常运行它们。

我怎样才能解决这个问题?

在此处输入图片描述

以下是我已经尝试过的方法:

  • 我没有安装任何扩展。
  • 我尝试恢复默认的 Gnome-Tweak 设置。
  • 我尝试重置 dconf。

以下是输出ls -l /usr/share/applications/

答案1

我今天在全新安装时遇到了同样的问题。我确信问题是由某些 snap 软件包引起的,最有可能是 snap store 和 gnome 桌面。

我的解决方案是彻底删除 snap。之后,我的所有应用程序启动器都恢复了。

由于 Ubuntu 22.04 还比较新,我们可能需要等待他们修复这个错误。
