I have a fresh install of 64-bit Ubuntu 10.04 with CUDA 3.2 (cudatoolkit_3.2.12_linux_64_ubuntu10.04.run), 260.19.14 drivers (devdriver_3.2_linux_64_260.19.14.run) and 3.2 SDK (gpucomputingsdk_3.2.12_linux.run). All SDK examples compiled successfully. 1 GPU currently attached: C2050 (which nvidia-settings picks up fine)
When I run deviceQuery, amongst other programs, the app(s) seem to just hang. No output, no errors. Interestingly, if I run deviceQueryDrv then it works as expected. Note, too, that I’m able to run some of the OpenGL examples, such as nbody.

No solutions, but another datapoint here – GTX 295 & 2 Tesla C2050s, deviceQuery gives no output, I don’t actually have a devicequeryDrv (no errors building though). Can also run (at least) nbody, fluidsGL and simpleMPI.
deviceQuery used to work when there were just 2 C2050s, making this even stranger…
64-bit Ubuntu 10.04, 260.29.21 drivers, all 4 devices show up in nvidia-settings (in a strange order – C2050, GTX295(1), GTX295(2), C2050), 3.2 SDK
