我运行的是 12.04 LTS，点击了“升级到 14.04 LTS”。现在我的屏幕只显示中间的一个白色窗口
屏幕说：
The system is running in low-graphics mode
Your screen graphics card, and input device settings
could not be detected correctly. You will need to configure
these yourself.
唯一的选择是“确定” ，我可以进入命令提示符（Ctrl++ ），但不知道从那里该做什么。AltF1
附件是我点击更新之前的“lspci”和“lshw”。

有25 分，你的系统最好使用 Lubuntu 或 Xubuntu，但无论如何，这是针对普通 Ubuntu 的解决方案：
请阅读以下警告：
点击Ctrl+ Alt+F1并输入以下命令：
sudo add-apt-repository ppa:xorg-edgers/ubuntusudo apt-get upgradesudo apt-get install nvidia-349sudo reboot
这应该可以解决问题！
