安装 Unity 2D 后缺少面板

Question

我将上网本从 UNR 10.10 升级到 Natty 11.04，它运行良好，直到我决定安装 Unity 2D。安装 Unity 2D 后，我尝试试一试并退出我的会话。当我尝试使用 Unity 2D 重新登录时，我只得到了背景信息。没有面板，也没有底座。我所有的图标都不见了。虽然我知道它正在工作，因为我可以使用键盘执行命令。现在我试图通过打开终端并输入来重置统一：

unity --reset

但是，这有效，但仅在我打开终端之前。当我关闭终端时，它又回到第一个正方形，我正在查看没有面板的背景。

还有一件事，这只发生在一个配置文件中。我的其他用户配置文件工作正常，我可以完全正常地访问和工作。

我相信我已经搞砸了我的管理员配置文件的图形卡设置。我不确定它具有哪种图形卡（我使用的是 Acer Aspire One D250 上网本）。

请帮忙 ！

这是 Unity --reset 命令的输出：

unity --reset

请尝试以下操作：

CTRL + ALT + F1

这将打开文本 TTY1

登录

类型

unity --reset-icons &

CTRL + ALT + F7 观看屏幕闪烁，然后应重置 Unity 启动器图标

然后

CTRL + ALT + F1 类型

unity --reset &

CTRL + ALT + F7 观看屏幕闪烁，并且 Unity Launcher + compiz 应重置

如果这不起作用，请尝试创建一个新的管理员帐户并将所有重要文件从旧帐户复制到新帐户。

如果“用户和组”窗口不起作用 - 尝试以下命令行条目：

sudo adduser newusername
sudo usermod -a -G admin newusername

显然将“newusername”更改为新帐户的名称。
