我正在尝试安装最新的 Nvidia 驱动程序。安装后nvidia-smi找不到它。
显卡是 GeForce 860m，我的笔记本电脑运行的是 Ubuntu 16.04.1 LTS。
我目前所做的：
$ 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.
尽管司机实际上正在行驶。
make.log包含如下行：
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[1]: Leaving directory '/usr/src/linux-headers-4.4.0-36-generic'
Makefile:81: recipe for target 'modules' failed
make: *** [modules] Error 2
答案1
gcc-4.8不支持-fstack-protector-strong
我安装了gcc-4.9该驱动程序，然后清除并重新安装，现在它运行正常。

具有讽刺意味的是，我之所以使用，是gcc-4.8因为IIRC，以前版本的 CUDA 与 4.9 或更高版本不兼容。
