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？
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。
