Hello,

On one computer I'm running Seti@Home using BOINC 7.6.22.
The OS is Fedora 26 Server 64-bit GNU/Linux, fully updated.
This machine has nVidia GeForce GTX 260 GPU and the latest (340.102) official nVidia drivers are installed using a patch which fixed the famous kernel build problem.
BOINC properly detects the GPU, but it doesn't use it (no GPU tasks), reporting that the nVidia drivers should be updated.
Do you have any suggestions on how to fix this?
This is the BOINC log:

Might this be a misleading error message for an old GPU with too limited a compute capability version number?

Is the GTX250 ok for other Boinc projects? Such as Einstein or GIMPS as a test?

Nvidia drivers from 340.xx do not work well with pre-Fermi GPU's so try a slightly earlier driver to see if you get the same problem.]

Cheers.

...using a patch which fixed the famous kernel build problem.

I think Ubuntu provides driver 304 for this series card, you might try that driver. If you still can't get tasks I'd recommend using Anonymous platform with this App, CUDA 4.2 App with CPU App tuned to run on Intel CPUs with at least SSSE3.
I don't know if the CUDA 42 App will work with that 'patched' 340, but it works well with my GTS 250 with driver 337.25 from nVidia in Ubuntu.

Thank you guys!
I didn't realized this GPU is so old.
I'll just try to change it to the one and I'll let you know about the results.
