BOINC doesn't seem to actually start GPUGRID tasks, and I'm not sure how long this has been the case on my machine. My computer has a GTX 260 and is running Ubuntu 11.10 (oneiric) 64-bit with the standard versions of all the relevant software from the repositories. That means BOINC 6.12.33 with proprietary NVIDIA driver 280.13 (Linux-x86_64). My event log looks like this:

The GPUGRID task simply remains in the "Ready to Start" state. At first I thought I might have done something stupid, like suspended the project temporarily and forgotten to reset it. But the status field under projects is blank. As you can see from the computer's page, it hasn't been working for a long time. That's because my computer's PSU died during the Thanksgiving break, and the new one took a long time to arrive. This one *should* be more than powerful enough to run everything if the per-rail amp ratings are right, though.
Any help would be appreciated. Thanks!

Uh, I just proofread that and I didn't mean "reset" in the last paragraph there. I meant resume.

I can't believe I did that, I had put it on "suspend GPU activity" while the PSU was dying and forgot to re-enable it afterwards. It was just a stupid mistake on my part, though it seems weird that it doesn't show up in the event log. Thanks.
