Been using nvidia-331 (proprietary, tested) prior to updating drivers
without problems. After this recent update, on restart Einstein@Home
reported "No GPU Available" to do GPU tasks (they were CUDA work
packets) and Blender reported me not having any CUDA or OpenCL devices
available. I might also had an AMD OpenCL ICD installed which enabled me
to see my CPU as on OpenCL device; now Blender doesn't even detect that.

Rolled back to legacy nvidia-304 (proprietary, tested) and uninstalled
non-nvidia OpenCL ICD related items to get my CUDA/OpenCL working.

As a test, I then upgraded back to nvidia-331-updates and ended up with
the same "no gpu available' / no OpenCL device detected. It is from
here, while changing driver to nvidia-331 (proprietary tested) that,
during the installation towards the last 1/4 or so I get a "System
Problem Detected" which has led me here.


Summary:

nvidia-331 (p/t) before package updates - all OK and working (may or may not have had an AMD OpenCL package installed - only nvidia cards and intel CPU in system)
nvidia-331 (p/t) after updates - no CUDA/no OpenCL
(random nvidia OpenCL ICD package addition/removal, I can't recall)
nvidia-304 (p/t) CUDA/OpenCL working again
nvidia-331-updates (p) no CUDA/no Opencl
trying nvidia-331 (p/t) results in "System Problem Detected (this issue" and doesn't install fully -> property page shows me as still running nvidia-331-updates


-=-=-=
On an unrelated note, I can't install different video card drivers in Synaptic -> Repositories -> Additional Drivers page, it gets stuck at ~10%. It's the exact looking property panel that is in Dash -> System Settings -> Software & Updates. Maybe the panel's waiting for Synaptic to close (to release the lock on the package list?).

Title:
  package nvidia-opencl-icd-331 (not installed) failed to
  install/upgrade: trying to overwrite '/usr/lib/x86_64-linux-gnu

Status in nvidia-graphics-drivers-331 package in Ubuntu:
  Confirmed

Bug description:
  I had installed the following 2 things from nvidia's website:

  1) The driver NVIDIA-Linux-x86_64-343.36.run

  2) cuda_6.5.19_linux_64.run (skipping the driver)

  
  I have a new computer with a GTX 980 and I haven't been able to run anything with CUDA yet. Installing `nvidia-331' was a somewhat desperate attempt to get the CUDA samples to run.

  In any case, dpkg should probably not bomb, no matter how misguided my
  attempts are.
