2018.02.08更新后ubuntu1604LTS后不能使用nvidia卡做gpu运算的问题

[OUC_LiuX]

如题，2018.02.08进行完一次内核更新后(不确定是否有必然关联)，执行gpu下深度网络训练出现(……35vs0……)报错。
检查系统设置，图形处理芯片被重置为inter核显。
nvidia-setting 包含i卡和n卡，但是选定n卡重启后无法奏效。
重装机后，nvidia-setting不再包括n卡。

已重装多个版本，包括1604 1610 1704，尝试多个内核，从4.13到4.15，都没有解决。

重装系统，还没有安装caffe。
现在使用lspci:
lspci | grep -i vga
00:02.0 VGA compatible controller: Intel Corporation HD Graphics 530 (rev 06)

lspci | grep -i 3d
01:00.0 3D controller: NVIDIA Corporation GM107M [GeForce GTX 950M] (rev a2)

驱动如图，安装了nvidia384，并且禁用了nouveau.

nvidia-settings如图：没有n卡项

[poloshiao]

選裝項目 可以試試
sudo apt install intel-microcode

或者 點選安裝
參見 附圖

你好，已操作并重启。没有任何改观

nvidia-settings如图：没有n卡项

NVIDIA X Server Settings_002.png

1. 安裝 gksu 套件
sudo apt install gksu

2. 按下 alt + F2
出現 輸入框
輸入
gksudo nvidia-settings
看看 與
NVIDIA X Server Settings_002.png
是否相同
2. 如果是登入 unity 桌面 也可以直接在 終端機 執行
gksudo nvidia-settings

你好，已安装，并重启。与NVIDIA X Server Settings_002.png 完全一致。

网传bios设置中，secure boot 项会导致机器不加载n卡，我检查后确定secure boot一直处于disable状态

你好，2018.02.10。
0，已禁用 nouveau, 命令 “lsmod | grep nouveau” 无返回信息;
1，更新驱动为 NVIDIA-390 + inter-microcode 如图

但 nvidia-smi：未找到命令
nvidia-settings， gksudo nvidia-settings 返回依然与 NVIDIA X Server Settings_002.png 完全一致。

是否支援 nvidia-settings ?
