Hello,

I have upgraded my video recently. I don't remember if CUDA was working with old card but it seems to be not working with new one.
I've tried a couple of things from the forums that did not help:
- restarted the boinc-client service
- run nvidia-modprobe than restart the service

Hello Victor, welcome to the boinc forums.

Probably need to set the coproc_debug flag for more details in the event log, however looking at what you've posted you may be missing the cuda libraries.

I'm not quite sure for fedora what the best place/method to get them but https://fedoraproject.org/wiki/Cuda might help.
