I start BOINC manually, never had any issues before the 334.21 drivers.
If the problem was that the video drivers weren't initialized when BOINC started, would restarting BOINC detect the GPU, or do you need to do a full reboot and then wait before starting BOINC for the first time?

I installed opencl-nvidia along with the nvidia update, and thought that the opencl package was the problem. Of course I removed it and it made no difference.
But yesterday I installed the opencl-nvidia package again, restarted boinc, and got this:

18-Mar-2014 13:31:58 [---] [coproc] launching child process at /usr/bin/boinc_client
18-Mar-2014 13:31:58 [---] [coproc] relative to directory /
18-Mar-2014 13:31:58 [---] [coproc] with data directory /var/lib/boinc
18-Mar-2014 13:31:58 [---] CUDA: NVIDIA GPU 0: GeForce GTX 760 (driver version unknown, CUDA version 6.0, compute capability 3.0, 2048MB, 1806MB available, 2499 GFLOPS peak)
18-Mar-2014 13:31:58 [---] OpenCL: NVIDIA GPU 0: GeForce GTX 760 (driver version 334.21, device version OpenCL 1.1 CUDA, 2048MB, 1806MB available, 2499 GFLOPS peak)
18-Mar-2014 13:31:58 [---] NVIDIA library reports 1 GPU
18-Mar-2014 13:31:58 [---] No ATI library found


And GPU tasks started running again.
Upon reboot, however, back to the original messages and no GPU found. I have tried to recreate this without success but maybe a reboot is needed somewhere in between.

I have exactly the same situation here, wondered why BOINC suddenly found no GPUs after that update.
