更改一些 compiz 设置后 Unity 损坏，全新 11.10 安装

Question

可能的重复：
Unity 在更改启动器图标大小后消失并且不会回来

我刚刚重新安装了 Ubuntu 11.10，然后使用 compizconfig 设置管理器更改（或尝试更改）Unity 启动器的某些设置。我只更改了 unity 插件中的一些设置，我认为更改了 alt-tab 切换器中的一些设置。然后，当我关闭 ccsm 时，它崩溃了，我的 unity bar 消失了，即使在几次重新启动、unity --replace、unity --reset 甚至重新安装与 unity 相关的所有内容后也不会返回。当我尝试在终端中启动 unity 时，这是我得到的输出：

unity --reset

关于如何解决这个问题的任何想法？我还安装了专有的 nvidia 驱动程序（推荐的当前版本），然后重新启动没有问题，只有在使用 ccsm 更改某些内容后它崩溃了，所以我认为这不是问题吗？
