For the past few days, I have been receiving messages saying that since I haven't the proper graphics card, that no GPU work units can be sent.
Only problem is, I wasn't aware that my client was asking for them.
I'm using the BOINC manager, so the only preferences I can set are through a webpage here, and not the command line. Suspending the GPU work while computer is in use under Computing Preferences doesn't seem to have any effect, and neither does selecting no for Use NVIDIA GPU if present. I still get the error message.
What's interesting is that I'm finishing a whole batch of CPU-only work units that downloaded just fine a few days ago without warnings. If there weren't any GPU wu's, it switched to getting CPU wu's. Not anymore, though.
