Switching from an ATI card to an nVidia one was not so simple, as X was configured to work with an ATI card. 从ATI的卡切换到nVidia的一个不是这样简单，因为X被配置为使用一个ATI卡。 What I had to do was to boot in Safe Gnome, download the nVidia drivers to my desktop, then enter the command line screen (pressing CTRL+ALT+F1), delete and reinstall X, edit /etc/X11/xorg.conf to use vesa drivers, install the nVidia drivers from my desktop, and then enjoy full video performance.我需要做的就是在安全侏儒启动，下载nVidia的司机到我的桌面，然后输入命令行屏幕（按CTRL + ALT + F1）的，删除并重新安装十，编辑/ etc/X11/xorg.conf来使用vesa的驱动程序，安装桌面上的NVIDIA驱动程序，然后享有充分的视频性能。 If you fail to do these steps, then you will run into a blank screen right after you log into your account.如果你没有做这些步骤，那么您将运行到一个空白屏幕右侧后登入您的帐户。
But even with the latest official nVidia drivers installed, the GUI inside Ubuntu will not be as smooth as expected.不过，即使官方最新的nVidia安装的驱动程序，内部Ubuntu的界面将不会如预期顺利。 To fix this, you'll need to install compizconfig-settings-manager from synaptic.要解决此问题，您需要安装 与compizconfig - settings从突触经理 。
After you install compizconfig-settings-manager, open it from System->Preferences->Compizconfig settings manager:在安装与compizconfig - settings - manager的，开放系统>“预置科技”的compizconfig设置管理：
Open Compizconfig-settings manager开放与compizconfig - settings经理
Then select the “ All ” category and go to “ General options “:然后选择“ 全部 ”类别，进入“ 常规选项 ”：
Open Compizconfig-settings manager General Options开放与compizconfig - settings经理常规选项
Then make sure that Detect Refresh Rate is unticked, Sync to VBlank is ticked and that the Refresh Rate is set to a slightly more number than your monitors refresh rate (if unsure, set it to 100):然后确保检测刷新率 unticked， 同步到VBlank是打勾，并刷新速率设置为1比您的显示器刷新率略为号（如果不确定，将其设置为100）：
