我刚刚安装了 17.04 服务器，然后安装了桌面，但我只有那些图标（这实际上不是我的设置，但它以同样的方式损坏了）
我尝试使用这些命令来尝试解决它：
sudo apt-get install ubuntu-desktop
sudo apt-get remove unity-control-center
sudo apt-get install unity-control-center
sudo apt-get install ubuntu-desktop
sudo apt-get install unity-control-center
sudo apt-get install unity-control-center-signon gnome-control-center-unity
sudo apt-get update --fix-missing
sudo apt-get -f install
但我没有成功解决它。你能建议一些方法来解决我的问题吗？
我重新安装了 ubuntu 桌面，没有更改 sudo apt-get install --reinstall ubuntu-desktop 0 升级，0 新安装，1 重新安装，0 删除，0 未升级。
我也这样做了

但它也只添加了一个图标。在线账户。
他们仍然缺少许多像力量这样的图标。
当我写作时gnome-control -center，它会带来很多图标，但是当我单击例如显示时，控制台会显示：

我安装了 xubuntu 并登录，设置相同。缺少图标。所以这与 unity 无关？
我有这些环境：
答案1
好的，我想我有一个解决方案。自从升级到 Ubuntu 17.04 以来，我一直遇到完全相同的问题，并且所有建议的解决方案都不适合我。
通过查看与缺少的图标条目相对应的 .desktop 文件，我发现了以下行：
OnlyShowIn=Unity7;
并unity --version返回unity 7.5.0，所以我想也许只是把
OnlyShowIn=Unity;
无需指定版本即可工作，然后图标开始重新出现在系统设置菜单中。
请注意，删除该行也有效。希望这能有所帮助。
答案2
Linux 4.3/4.4 中有一个已知错误，会导致文本损坏或图像偶尔消失。可能值得测试 4.2，间歇性混乱的文本应该可以正常工作。
