Unable to process on NVIDIA GeForce GTX 750 Ti

[jetchko.jekov]

Can someone explain what is happening here and why can't I use my NVIDIA GPU for folding?
Ever after installing F@H I am unable to run any WU on this GPU and in the logs, I see this (many times over):

This is the failure line and I'd guess it's a GPU driver problem, mis-reporting what your GPU is. Hopefully, someone more knowledgeable about Linux will be along shortly.

Which video drivers are you using? AIUI, you have to be using the closed source drivers from the vendor, not the open source ones.

Oh, sorry I cross-posted it here by mistake.
Anyway, thanks. I managed to fix my problem.
