Finally: blacklisting the nouveau-drivers and disabling OpenCL via cc_confog.xml did do the trick - thanks!!! :-)

Now crunching again with 8 CPUs and 2 GPUs :-)

I have a fresh new Fedora 29 installation but can't run any GPU-task. Boinc client shows the following messages on start-up:

26-Dec-2018 17:02:09 [---] App version needs CUDA but GPU doesn't support it


When I add Einstein@home it tries to use the ATI-GPU but fails with "calculation error" immediately. The already existing SETI@home-tasks are all rejected due to missing CUDA (buth which is there, all Nvidia/CUDA packages are installed).

So...any idea what could be wrong/what to check?

Thanks!
