我的系統上安裝了 ubuntu 14.04，一切正常，直到我嘗試安裝顯示卡（nvidia gt 630）。我把顯示卡裝到電腦上，把顯示器插到顯示卡上，沒有輸入。顯示器可辨識已插入電源，但未接收任何輸入。然後我將顯示器插入板載顯示卡端口，系統在低圖形模式下運行。我已嘗試多次安裝 nvidia 驅動程序，但仍然無法在附加驅動程式選單中顯示任何內容。
我嘗試使用以下命令安裝驅動程式：
sudo apt-get install nvidia-304-updates
問題似乎是驅動程式沒有安裝，而且我沒有 ubuntu 通常附帶的標準驅動程式。我在清單中看到的唯一顯示卡驅動程式是英特爾顯示卡驅動程式。

答案1
首先nvidia-304-updates是你的卡的驅動程式錯誤。以這種方式安裝正確的
sudo apt-get purge nvidia*
sudo apt-get install nvidia-346
並重新啟動。如果仍未偵測到適配器，請嘗試這個解決方案。
答案2
安裝並重新啟動後，我無法工作，直到我在 BIOS 中關閉英特爾圖形加速。顯然，如果您只使用專用的 Nvidia 卡，則該選項會發生衝突。
