登录后 Gnome 3 总是挂起

Question

我遇到的问题是，登录后进入GNOME Shell 3.4.1的Ubuntu 12.04.1 LTS。

一小段时间（大约 0-2 分钟）后，gnome shell 变得没有响应。

将鼠标悬停在角落上/单击活动按钮没有任何作用，
Windows 卡住了（应用程序正在响应，但 gnome 没有响应）
此外，Alt+F2也没有任何作用。

我知道如何解决此问题的唯一方法是按
Ctrl+ Alt+转到 linux shell any from F1 to F6，登录并重新启动 lig​​htdm 服务。

sudo service lightdm restart 

所以问题是如何解决登录后 Gnome 3 挂起的问题？

我在 Ubuntu 12.04 和 Gnome 3.4 上也遇到了类似的问题。我通过执行以下操作设法最大限度地减少冻结频率：

• 禁用专有视频驱动程序
• 将ppa:gnome3-team/gnome3添加到源并更新
• 您也可以尝试等待 30 秒。这可能听起来很愚蠢，但我认为当登录屏幕呈现给用户时，并非所有组件都已准备好。（你可以责怪 Canonical 试图在启动时间上作弊:)）

唯一能永久解决这个问题的方法是升级到 Ubuntu 12.10 和 Gnome 3.6，至少对我来说是这样。
