NVIDIA 驱动程序问题 Ubuntu 16.04

Question

我正在尝试安装最新的 Nvidia 驱动程序。安装后nvidia-smi找不到。

显卡是 GeForce 860m，我的笔记本电脑在 Ubuntu 16.04.1 LTS 下。

到目前为止我做了什么：

$ sudo apt-get purge nvidia-*
$ sudo add-apt-repository ppa:graphics-drivers/ppa
$ sudo apt-get update
$ sudo apt-get install nvidia-367
$ reboot
$ nvidia-smi
NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.

我怎样才能让它工作？

编辑：我意识到$ sudo apt-get install nvidia-367返回了错误：

Error! Bad return status for module build kernel: 4.4.0-36-generic (x86_64)
Consult /var/lib/dkms/nvidia-367/367.44/build/make.log for more information.

尽管驱动程序实际上正在运行。

make.log 包含这样的行：

Makefile:676: Cannot use CONFIG_CC_STACKPROTECTOR_STRONG: -fstack-protector-strong not supported by compiler

和这个：

cc: error: unrecognized command line option ‘-fstack-protector-strong’
scripts/Makefile.build:258: recipe for target '/var/lib/dkms/nvidia-367/367.44/build/nvidia/nv-instance.o' failed
make[2]: *** [/var/lib/dkms/nvidia-367/367.44/build/nvidia/nv-instance.o] Error 1

make[1]: *** [_module_/var/lib/dkms/nvidia-367/367.44/build] Error 2
make[1]: Leaving directory '/usr/src/linux-headers-4.4.0-36-generic'
Makefile:81: recipe for target 'modules' failed
make: *** [modules] Error 2

Answer 1

gcc-4.8 不支持 -fstack-protector-strong

我gcc-4.9改为安装，清除并重新安装驱动程序，现在它工作正常。

具有讽刺意味的是，我使用gcc-4.8IIRC 是因为以前版本的 CUDA 与 4.9 或更高版本不兼容。
