Here is my problem. I have a Nvidia Quadro RTX 4000 installed on my ubuntu 18.04 workstation. I do not manage to get a graphics output from the nvidia card, instead I am using the output from the onboard aspeed graphics card.
I have installed Cuda 10.1 according to the nvidia website and my card is found by nvidia-smi

If I start nvidia-settings I get an error message
ERROR: Unable to load info from any available system
If I want to start for instance the particles cuda test program a window opens and closes again immediately with the output
CUDA Particles Simulation Starting...

Interestingly BOINC finds the graphics card and can run CUDA and OpenCL code.
I am really confused about this problem. I will also attach the nvidia bug report.
