14.04 LTS 通过软件更新程序更新后没有 Dash/启动器

14.04 LTS 通过软件更新程序更新后没有 Dash/启动器

我登录后没有看到 Dash / Launcher。这是通过软件更新程序更新后出现的。请帮忙修复...我已经花了一天时间尝试 askubuntu.com 上发布的不同选项。但都不起作用。

通过 Ctl + Alt + F1 进入终端并成功登录。

Here are the logs:

更新(2014 年 6 月 8 日):

Okay, I have reset unity, but I cannot login normally via the login screen.
Steps I follow:
1. Login screen -> blank ... No dash / no launcher / No Status (Notification) Bar on top
2. Ctrl+Alt+F1 to bash terminal
3. export DISPLAY=:0
4. unity-tweak-tool --reset-unity (This does not complete, blocks on OpenGL)
5. I anyways continue to by doing: Ctrl+Alt+F7.
6. Launcher & Dash look good. But there is (a) No Status / Notification Bar on top
7. Continuing to work this way. Haven't logged out since.

答案1

我遇到了类似的问题,我通过切换终端(CTRL + ALT + F1)然后删除配置文件〜/ .config / dconf / user来解决它,如下所示:

(!此操作将删除您的 gnome 3 设置!)

sudo service lightdm stop
rm ~/.config/dconf/user
sudo service lightdm start

答案2

首先,检查你的机器是否已完全更新。打开命令行(Ctrl++ AltF1

sudo apt-get update
sudo apt-get dist-upgrade

如果出现任何错误,请运行:

sudo apt-get install -f

然后重新运行前两个命令以确保没有进一步的错误。之后您可以尝试登录(Ctrl- Alt-F7切换到您的 GUI)以查看 Unity 是否正在运行。

如果 Unity 仍无法运行,请按照以下说明重置 Unity 配置(来自如何重置我的 Unity 配置?):

使用 14.04 安装 unity-tweak-tool:

sudo apt-get install unity-tweak-tool

然后运行以下命令将 Unity 重置为默认值:

unity-tweak-tool --reset-unity

答案3

尝试这样做,效果很好:

Ctrl+ Alt+F1/F2

输入您的登录名和密码并运行以下三个命令:

sudo service lightdm stop
rm ~/.config/dconf/user
sudo service lightdm start 

答案4

我遇到了类似的问题,并且尝试了上面列出的几乎所有解决方案。结果发现这是主目录权限的问题。可能是 FTP 传输重置了目录权限。以下是我用来修复该问题的命令

sudo chown /home/ sudo chown /home//.Xauthority
