系统设置不再显示

tag-icon • tag-icon 14.04 unity settings system-settings dialog
系统设置不再显示

当我将装有 Ubuntu 14.04.1 的硬盘放入新 PC 后，系统设置不会显示。我尝试过：

sudo apt-get install unity-control-center

但我明白

我能做些什么？

编辑

这个问题可能与我从xorg edgers我注意到

  • unity-control-center依赖于取决于libcheese7
  • libcheese7依赖于取决于gstreamer1.0-clutter
  • gstreamer1.0-clutter依赖于取决于libcogl15
  • libcogl15 depends在libegl1-mesa-drivers
  • libegl1-mesa-drivers依赖于取决于libegl1-mesa-drivers
  • libegl1-mesa-drivers依赖于取决于libglapi-mesa ( = 10.1.3-0ubuntu0.3 )

我已经安装了：

libglapi-mesa 10.5.0~git20150105.21a280f8-0ubuntu0ricotz~trusty来自 xorg-edgers PPA。

我尝试使用以下方法安装它：

sudo apt-get install libglapi-mesa=10.1.3-0ubuntu0.3

我已经禁用了 PPA

sudo ppa-purge  ppa:xorg-edgers/ppa && sudo apt-get update

答案1

因此问题出在依赖关系上，即

libegl1-mesa-drivers取决于libglapi-mesa ( = 10.1.3-0ubuntu0.3 )（也许应该是>=）

我再次添加了 xorg-edgers PPA，然后使用 ppa-purge 进行了正确降级，如下所示：

sudo add-apt-repository ppa:xorg-edgers/ppa && sudo apt-get update
sudo ppa-purge  ppa:xorg-edgers/ppa && sudo apt-get update

现在我已删除了 xorg-edgers 中的所有软件包，并且系统设置对话框打开了 :)

答案2

有一个错误报告这里。（解决方案来自#10条回复）

显然，通过输入以下行，我的问题得到了解决：

sudo apt-get install libglew-dev libcheese7 libcheese-gtk23 libclutter-gst-2.0-0 libcogl15 libclutter-gtk-1.0-0 libclutter-1.0-0

答案3

尝试执行sudo apt-get install -f unity-control-center或搜索缺少的包名称并手动安装它们。
