Unity 无法加载 - 没有出现启动器或 Dash

我使用的是 32 位Ubuntu 14.04 LTS在我的简单台式电脑（3GHz Intel P4、1GB RAM、Intel 内置显卡、没有额外的显卡）上，所以无需担心 nvidia 等显卡。

输出如下lspci：

我已经安装了xubuntu-desktop环境，unity-tweak-tool并且已经运行了 3 个月。

最近我遇到了一个问题：Unity 无法加载，没有启动器，也没有出现 Dash。我尝试了这些答案，但无法解决我的问题。

这可能是因为我ubuntu-tweak最近才安装的。因此，我也将其从 tty 中删除，但无法解决这个问题。

我做任何事都有三种方法：

  1. 使用 tty ( Ctrl+ AltF1)
  2. 我已经安装好了nautilus-open-terminal，因此我可以gnome-terminal通过右键单击桌面并“在此处打开终端”来启动。
  3. 使用 Xubuntu Session。

我尝试过以下事情：

  • 启用 unity-plugin (https://askubuntu.com/a/76951/256099）但并未解决。
  • dconf reset -f /org/compiz/从gnome-terminal
  • 清除并重新安装unity，compiz并且ubuntu-desktop
  • 已删除缓存rm -rf ~/.compiz-1 ~/.config/compiz-1，，，，sudo rm -fr ~/.compizsudo rm -fr ~/.cache/*sudo rm -fr .cache/*
  • 尝试通过以下步骤替换/重置 unity gnome-terminal：
    1. unity --replace
    2. setsid unity
    3. ubuntu-tweak-tool --reset-unity

输出-1，输出-2

全部显示共同点：

我可以尝试重新安装整个操作系统。或者，有什么方法可以解决这个问题？

现在该怎么办？（是否可以重新安装整个 Unity 桌面环境并使用全新的 DE 而不会出现这样的问题？）

答案1

尝试：

恢复默认设置

在终端中一次执行以下命令。

gconftool --shutdown
sudo killall -r -I gconf
sudo killall -r -I dconf
rm -rf .compiz* .gconf* .config/dconf/ .config/compiz*

请注意，上述命令将删除您已完成的所有设置或配置。键盘布局（如果有）也将被删除。虽然上述命令不会删除任何文件，但它们将恢复您首次安装 Ubuntu 时的 Unity 设置。

重新启动系统以使更改生效。

有一次我遇到过同样的事情，所以这里是我得到的有效答案。
