Got three copies of this message today (I have two GPUs):

I checked all the preferences I could see in the BOINC client, and in the Computing prefs on this site; I don't see anything related to GPU. How do I enable GPU computing?

I'm on Linux, running as a service, so it shouldn't be that the process doesn't have access to the GPU.
