Hi, |
2 |
|
3 |
after upgrading to nvidia-drivers-396.51 no CUDA devices were found. |
4 |
Last version, which works for me is nvidia-drivers-396.24-r1. |
5 |
|
6 |
The problem was detected first while using Blender which normally |
7 |
renders on GPU but falls back to CPU rendering then (jawn!). |
8 |
|
9 |
I submitted a bug report to the blender devs and Brecht van Lommel |
10 |
pointed me to the tool http://cuda-z.sourceforge.net/. |
11 |
|
12 |
After installing that it shows that there are CUDA devices detectable |
13 |
with the old driver and none with all drivers newer than that. |
14 |
|
15 |
So it is no blender related problem. |
16 |
|
17 |
libcuda is installed with both versions of the driver and checked for |
18 |
being of the currently installed version. |
19 |
|
20 |
How can I fix that? |

Two Nvidia-cards are installed. One for the desktop |
30 |
and one for Blender alone: |
31 |
02:00.0 VGA compatible controller: NVIDIA Corporation GM206 [GeForce GTX 960] (rev a1) (Desktop) |

Software: Linux kernel 4.18.00 currently. The same problem was arises |
35 |
with older kernels (4.17 ..). |
