Description Jérôme Hénin 2018-08-03 16:09:26 CEST

Description of problem:
I cannot get any CUDA app to run on a machine with an NVIDIA MX150 GPU and an Optimus setup. Both Bumblebee and mageia-prime give the same result.

I'm using 390.77 from updates-testing-nonfree, and kernel 4.14.40 because of bug 23296.

- with CUDA 8.0 from Mageia repos:
CUDA apps tell me:
> CUDA driver version is insufficient for CUDA runtime version

Apparently support for MX150 was only added in CUDA 9.1 (https://devtalk.nvidia.com/default/topic/1023574/announcements/cuda-toolkit-9-is-not-available-in-geforce-mx150/), which requires driver version 390.46 or higher (https://docs.nvidia.com/cuda/cuda-toolkit-release-notes/index.html).

- testing with CUDA 9.1 downloaded from NVIDIA:
Despite the official compatibility chart, CUDA apps tell me:
> CUDA driver version is insufficient for CUDA runtime version
so, same result.

Version-Release number of selected component (if applicable):
390.77

I'd like to test a more recent driver (and possibly CUDA 9.2) but I'm afraid I'll ruin the subtle combination of drivers for Optimus/Bumblebee that I get from the nice mga packages :-(
Is there a plan to package the latest driver? Anything I can do to help?

How reproducible:
Everytime

Assigning to the kernel & drivers maintainers

Note that there is also bug 22862 "CUDA does not work without x11-driver, please move some files from x11-driver-video-nvidia-current to nvidia-current-cuda-opencl", that was filed against cauldron.
