我的系统上安装了 ubuntu 14.04，一切运行正常，直到我尝试安装显卡（nvidia gt 630）。我将显卡放入计算机，并将显示器插入显卡，但没有输入。显示器识别到它已插入，但没有收到输入。然后我将显示器插入板载显卡的端口，系统以低图形模式运行。我尝试多次安装 nvidia 驱动程序，但仍然无法在附加驱动程序菜单中显示任何内容。
我尝试使用以下方法安装驱动程序：
sudo apt-get install nvidia-304-updates
问题似乎是驱动程序未安装，而且我没有 ubuntu 通常附带的标准驱动程序。我在列表中看到的唯一图形驱动程序是英特尔的。

答案1
首先，nvidia-304-updates您的显卡驱动程序错误。请按照以下方法安装正确的驱动程序
sudo apt-get purge nvidia*
sudo apt-get install nvidia-346
并重新启动。如果仍未检测到适配器，请尝试此解决方案。
答案2
安装并重启后，它无法正常工作，直到我在 BIOS 中关闭了 Intel 图形加速。显然，如果您只使用专用的 Nvidia 卡，则该选项会发生冲突。
