升级内容有很多好处，比如支持最新硬件驱动，使系统更安装等。但是升级内容也会带来一些问题，比如一些软件的兼容性问题，从而出现一些莫名其妙的问题等，所以升级时要慎重考虑。

升级方法：

下载脚本：

使用：

mv install_OCL_driver.txt install_OCL_driver.shchmod 755 install_OCL_driver.shsudo su./install_OCL_driver.sh install

完成后的提示信息：

...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 foo2. 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 kernelHINT: 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。
