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
