ubuntu16.04附加驱动添加nvidia驱动失败，想问一下是源的问题吗，添加应用更改后进度条一直停在中间位置，我用的是中科大的源。

跟源應該沒關係

你的顯卡是雙顯卡 具備 Optimus 功能
需要安裝 閉源驅動 nvidia
試試安裝 nvidia-340
而你目前預裝的是 開源驅動 nouveau

手动安装吗，上次试过直接在附加驱动里添加是可以的，现在不行

從終端機 下指令 安裝看看
sudo apt install nvidia-340
如果有錯誤訊息 複製 貼上來
如果安裝順利 重新開機

需要拉nouveau进黑名单吗

http://packages.ubuntu.com/xenial/amd64 ... 0/filelist
在 xenial 發行版中 amd64 硬體架構下的 nvidia-340 套件文件清單

安裝 nvidia 已包含
/etc/modprobe.d/nvidia-340_hybrid.conf
你可以檢查一下 這個檔案
是否已經把 nouveau 列进黑名单 ?

好的我试一下，因为上次安装n卡失败导致进不了系统，然后重装了

您希望继续执行吗？ [Y/n] Y
更换介质：请把标有
“Ubuntu 16.04.2 LTS _Xenial Xerus_ - Release amd64 (20170215.2)”
的盘片插入驱动器“/media/cdrom/”再按「回车」键

sudo cat /etc/apt/sources.list
請把結果複製貼上來

養成習慣
安裝任何套件前 先
sudo apt update
sudo apt upgrade
沒有錯誤訊息
再開始安裝

1. 先確認一下 不是在試用桌面 ？
1-1. df /
把結果貼上來

2. 如果確定不是試用桌面
2-1. 安裝 gksu 套件
sudo apt install gksu
2-2. gksudo gedit /etc/apt/sources.list

2-3. 在前面加一個 #
# deb cdrom:[Ubuntu 16.04.2 LTS _Xenial Xerus_ - Release amd64 (20170215.2)]/ xenial main restricted
2-4. 儲存 然後
sudo apt update
sudo apt install nvidia-340

1. 應該是已安裝的 Ubuntu

2. 已安裝的 Ubuntu 應該已經加上 #

3-1. 可能是網路問題
3-1-1. 晚上夜深人靜時 再試試
3-1-2. 換一下 下載伺服器 再試試
3-1-3. 其它可能原因

nvidia驱动安装成功，感谢
