Ubuntu 16.04 安装英伟达（Nvidia）显卡驱动

配有英伟达显卡的主机，装完 Ubuntu 16.04 后出现闪屏现象，是由于没有安装显卡驱动。

显卡型号
NVIDIA Corporation GM204 [GeForce GTX 970]

Here are the steps to installing and setting up GDB on Mac OS Sierra/High Sierra. Run brew install gdb. On starting gdb, you will get the following error:

Unable to find Mach task port for process-id 2133: (os/kern) failure (0x5).
 (please check gdb is codesigned - see taskgated(8))

To fix this error, follow the following steps:

	#!/usr/bin/env python
	"""This is a demonstration of sharing file descriptors across processes.

	It uses Tornado (need a recent post-2.0 version from github) and the
	multiprocessing module (from python 2.6+). To run it, start one copy
	of fdserver.py and one or more copies of testserver.py (in different
	terminals, or backgrounded, etc). Fetch http://localhost:8000 and
	you'll see the requests getting answered by different processes (it's
	normal for several requests to go to the same process under light
	load, but under heavier load it tends to even out).

	# note: The easy and quick way to install is
	# sudo pip3 install opencv-python
	# sudo pip3 install opencv-contrib-python
	# But this easy pypi installation can’t open video files on GNU/Linux distribution or on mac OS X system.
	# And on some system opencv binaries provided packages are not compiled.
	# Therefor we have no way rather than build it from source.
