显卡是gtx965m，装了16.04LTS，一般系统应该带有NV驱动的吧，就是不确定是否正常，敢问该如何检测驱动正常，这样才能知道需不需要另外装驱动

1. 如果可以登入桌面
把下面指令 複製 貼進終端機 執行
1-1. uname -a
1-2. sudo lspci -knn
1-3. sudo lshw -numeric -class video
1-4. sudo ubuntu-drivers devices
把結果全部直接 選取/複製/貼上來

1. 參閱
http://askubuntu.com/a/679709
Phoronix has reported some issues with Skylake CPUs and Ubuntu.
There are also workarounds available.
1-1. 看看這些 workarounds 有沒有幫助

2. 顯卡 GeForce GTX 965M 沒有作用中 驅動
2-1. 把下面指令 複製 貼進終端機 執行
lsmod | grep nouveau
看看開源驅動 nouveau 是否已被載入

3. 試試 nvidia-367
3-1. 先把 nvidia-361 移除
3-2. 從 ppa:graphics-drivers/ppa 安裝 nvidia-367 nvidia-settings
https://launchpad.net/~graphics-drivers ... ubuntu/ppa
nvidia-367 (nvidia-graphics-drivers-367 367.27-0ubuntu0~gpu16.04.1)
nvidia-settings (367.18-0ubuntu0~gpu16.04.1)
3-3. 安裝方法 參閱
