在尝试过 gnome 桌面并在 Ubuntu 14.04 中切换回 unity 后，我遇到了一种奇怪的问题。我尝试卸载所有不必要的 gnome 软件包。
现在，在此之后，我观察到第一次登录后，gedit只有打开两次后才能打开。但是一旦在该登录中打开和关闭它，它就会正常运行。我想知道这里调整了什么？
编辑＃1：
在终端中执行 gedit 时出现错误消息
** (gedit:3422): 严重 **: 文件 log.c: 第 980 行: 意外错误: 为 org.gnome.zeitgeist.Engine 调用 StartServiceByName 时出错: GDBus.Error:org.freedesktop.DBus.Error.Spawn.ExecFailed: 无法执行程序 /usr/bin/zeitgeist-daemon: 成功 (g-dbus-error-quark, 23)

答案1
该错误与 zeitgeist 服务（用户活动跟踪器）有关。DBus 无法生成它。/usr/bin/zeitgeist-daemon它的一个或一个配置已被删除或损坏。
无论如何，解决问题的快速方法是重新安装所有相关软件包
sudo apt-get install --reinstall zeitgeist-datahub libzeitgeist-1.0-1 \
zeitgeist-core python-zeitgeist zeitgeist libzeitgeist-2.0-0 nautilus
答案2
所以我在这里收集的信息是您在 Ubuntu 上添加了另一个桌面环境？很抱歉，如果确实如此，您将不得不重新安装 Linux。无论出于何种原因，添加桌面环境似乎会破坏 Linux。本网站应为您提供有关在 Linux 中应避免做的事情的信息。

当我尝试在 Linux Mint 18 上安装 KDE 桌面环境时，我自己也犯了同样的错误；它使用桌面环境 Cinnamon。最终结果导致操作系统不断更改分辨率，无论出于何种原因，如果不这样做，屏幕就会变得模糊。我最终选择使用 Ubuntu，但我不喜欢标准的 Ubuntu 外观，所以我选择了 Kubuntu。
