之前的现象描述
办公电脑的显卡是Intel HD Graphics 630，系统是 Ubuntu 16.04 x64 版本，之前外接一个 VGA 显示器时使用正常。最近又外接了一个 HDMI 显示器做扩展屏幕，发现系统经常死机，只能强制重启，升级了 kernel 之后也没有解决。找到了这篇教程，自己也整理一下。
升级4.7的内核，步骤如下：
下载脚本：
/en-us/forums/opencl/topic/738108
使用：
mv install_OCL_driver.txt install_OCL_driver.sh
chmod 755 install_OCL_driver.sh
sudo su
./install_OCL_driver.sh install
完成后的提示信息：
...
Installation completed successfully.
Next steps:
Add OpenCL users to the video group: 'sudo usermod -a -G video USERNAME'
e.g. if the user running OpenCL host applications is foo, run: sudo usermod -a -G video foo
If you have Intel Pentium J4000 or Intel Celeron J3000, you will need to add:
i915.preliminary_hw_support=1
to the 4.7 kernel command line, in order to enable OpenCL functionality for these platforms.
Reboot into the patched 4.7 kernel
HINT: to boot into the 4.7 kernel do the following:
1) Hold the "shift" button during boot
2) When the GRUB menu appears, select "Advanced options for Ubuntu"
3) Select the Linux 4.7.0.intel.r5.0 kernel from the list
重启后即可。
如果中途出现APT的错误，参考：/EasonJim/p/7343892.html
install_OCL_driver.sh
#!/bin/bash
#
# Installs the Graphics Driver for OpenCL (SRB5.0) on Linux.
#
# Usage: sudo -E ./install_OCL_driver.sh [OPTION]...
#
# Supported platforms:
# 5th, 6th or 7th generation Intel® processor with Intel(R)
# Processor Graphics Technology not previously disabled by the BIOS
# or motherboard settings or Intel Pentium J4000 and Intel Celeron
# J3000 processors.
#
# Official document:
# http://registrationcenter-/akdlm/irc_nas/11396/SRB5.0_linux64.zip
# replace this with link to download
#
# Optimization note: at the end of installation you will have on:
#
# 1) CentOS
# /rpmbuild/RPMS/x86_64/kernel-4.7.0.intel.r*-1.x86_64.rpm
# /rpmbuild/RPMS/x86_64/kernel-devel-4.7.0.intel.r*-1.x86_64.rpm
#
# 2) Ubuntu
# /linux-image-4.7.0.intel.r*-*.deb
# /linux-headers-4.7.0.intel.r*-*.deb
#
# You may deploy these packages on other systems you have, and
# then launch this script on these systems. This will result in a
# *significantly faster* installation time.

Installed to successfully message:
...
Installation completed successfully.
Next steps:
1. Add OpenCL users to the video group: 'sudo usermod -a -G video USERNAME'
e.g. if the user running OpenCL host applications is foo, run: sudo usermod -a -G video foo
2. If you have Intel Pentium J4000 or Intel Celeron J3000, you will need to add:
i915.preliminary_hw_support=1
to the 4.7 kernel command line, in order to enable OpenCL functionality for these platforms.
3. Reboot into the patched 4.7 kernel
HINT: to boot into the 4.7 kernel do the following:
1) Hold the "shift" button during boot
2) When the GRUB menu appears, select "Advanced options for Ubuntu"
3) Select the Linux 4.7.0.intel.r5.0 kernel from the list
