Hi to the CUDA community,
I am running Ubuntu 18.04, with a GTX1060 graphics card. The driver is 440.46 and CUDA version is 10.2.
I did have CUDA 10.2 working about 4 months ago and something “broke” between then and now.
I looked at some documentation and decided that it would be best if I reinstalled the NVIDIA driver and then did a reinstall of CUDA.
Yes, I did uninstall the NVIDIA driver and reinstalled it from the command line with the X server turned off. That was successful. Before the install I did:
sudo rm nvidia* and everything, including cuda went away.
Also, the nouveau driver was blacklisted.
Testing one of the CUDA samples “clock” I received the following error:
The error 803 documentation reads:
cudaErrorSystemDriverMismatch = 803
This error indicates that there is a mismatch between the versions of the display driver and the CUDA driver. Refer to the compatibility documentation for supported versions.
