Bug#939145: blender Version:2.80+dfsg-3 CPU opencl not working in combo with video card

["Leo L. Schwab" <ewhac@ewhac.org>]

Package: blender
Version: 2.80+dfsg-3+b1
Followup-For: Bug #939145

Dear Maintainer,

	This may be related:  When attempting to enable OpenCL in the
preferences, a small panel appears claiming: "No compatible GPUs found
for path tracing.  Cycles will render on the CPU."

	I have an NVIDIA GTX-1070Ti with proprietary DKMS drivers
installed, version 430.40.  I also have Darktable installed;
`darktable-cltest` runs successfully, and (in part) outputs the
following info:

```
[opencl_init] device 0: GeForce GTX 1070 Ti
     GLOBAL_MEM_SIZE:          8116MB
     MAX_WORK_GROUP_SIZE:      1024
     MAX_WORK_ITEM_DIMENSIONS: 3
     MAX_WORK_ITEM_SIZES:      [ 1024 1024 64 ]
     DRIVER_VERSION:           430.40
     DEVICE_VERSION:           OpenCL 1.2 CUDA
```

	Hope this helps.

					Schwab
