14.04通过软件更新程序更新后的LTS无Dash /启动器

Question

登录后我就没有Dash / Launcher。这是在通过软件更新程序进行更新之后开始的。请帮忙修理..。我已经浪费了一天时间在askubuntu.com上尝试不同的选项。什么都没用。

通过Ctl + Alt + F1到达终端，并成功登录。

Here are the logs:

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.

Answer 1

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

(!此操作将删除gnome 3设置!)

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

Answer 2

我有一个类似的问题，我尝试了上面列出的几乎所有的解决方案。原来这是主目录的权限问题。可能是FTP传输重置了目录权限。下面是我用来解决这个问题的命令

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

Answer 3

CTRL-ALT-F1

-v ~/..gconf~/..gconf旧

然后代码：选择

mv -v ~/..config/dconf~/..config/dconf-old

然后注销/打开

重命名conf文件并生成一些新文件。
