I am trying to run SETI@Home on my GTX 750 Ti in Fedora 20 and AFAIK everything is configured correctly and if I look at the machine details on my account, it shows the correct GPU, but there is a file in my /var/lib/boinc directory named coproc_info.xml which reads :

NVIDIA drivers present but no GPUs found No ATI library found clGetPlatformIDs() failed to return any OpenCL platforms

as well as a file named stderrgupdetect.txt which reads:

libkmod: conf_files_list: opendir(/etc/modprobe.d): Permission denied
libkmod: conf_files_list: opendir(/etc/modprobe.d): Permission denied

If somebody helps me to get this working, there will be another GPU searching for alien oscillators! Let me know what other info you need.

Are you running stock Bonic for seti or you using Lunatic? That line says "no GPUs found no ATI library found" ATI refers to AMD Graphic cards.. You also might want to post over in Number Crunching in the Message Boards area, it gets more traffic and more experienced users that can answer your question

I am running stock BOINC, installed by #yum install boinc-client.x86_64 boinc.manager.x86_64. I will post this in number crunching as well, thanks.
