[PyCUDA] Error after Updating from Ubuntu 13.10 to 14.04

[elodw]

Hello,

after updating
i get the following errror runing a pycuda-program

import pycuda.autoinit
File "/usr/lib/python2.7/dist-packages/pycuda/autoinit.py", line 4,
in <module>
cuda.init()
pycuda._driver.RuntimeError: cuInit failed: no device

For what it is worth, my 13.10 working pycuda install failed after
upgrading to 14.04. Ubuntu's and Debian's installation directories do
not match nvidias so it is hard to unravel what's missing.

Autoinit fails for me in the same way. The version of cuda on 1404 is
5.5.

Check whether the system is running the nouveau drivers rather than the nvidia
ones; I've been able to successfully use the stock Ubuntu python-pycuda package
with the nvidia-331-updates driver package installed.

Upgrading Nvidia-driver from 304.117 to 331.38
solves the pyCUDA-Problem
but now there are light Graphic-Problems.

You may need to play around with the driver settings using nvidia-settings.
