Thank you for your answer, Micha.  I've blacklisted the nouveau
module, created a xorg.conf for Intel via the Xorg -configure command
and installed the nVidia driver. All works: integrated graphics for
normal use and nVidia for CUDA.

As a detail, I've tried to use the nVidia as defaulr card generating
the corresponding xorg.conf via nvidia-xconfig but it not works. I
don't know if additional configuration is needed. For me is not

Thanks again
