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

短时间（约0-2分钟）后，gnome shell变得无响应。

徘徊在角落里/点击活动按钮不会做任何事情，
视窗卡住（应用程序响应，但在gnome是不是）
另外，Alt+ F2不会做任何事情。

我知道如何解决此问题的唯一方法是通过按
Ctrl+ Alt+ 进入Linux shell any from F1 to F6，然后登录并重新启动lightdm服务。

sudo service lightdm restart 

那么问题是如何解决登录后Gnome 3挂起的问题？

提前致谢。

我在Ubuntu 12.04和Gnome 3.4中遇到了类似的问题。通过执行以下操作，我设法将冻结频率降到最低：

• 禁用专有视频驱动程序
• 将ppa：gnome3-team / gnome3添加到源代码并更新
• 您也可以尝试等待30秒。在登录之前。这听起来很愚蠢，但是当我向用户显示登录屏幕时，我认为并不是所有组件都准备就绪。（您可以责怪Canonical试图欺骗启动时间：））

至少就我而言，唯一能够永久解决此问题的方法是升级到Ubuntu 12.10和Gnome 3.6。

解决方法

由于这是Flash安装，因此我们可以创建一个新用户。

1. 从文本终端登录

2. 添加新用户

   sudo adduser <username>
   

3. 将新用户添加到sudo组，或admin

   sudo adduser <username> sudo
   

4. 切换回X并尝试使用新用户登录

尝试的事情

• 更新资料

  sudo apt-get update
  sudo apt-get dist-upgrade
