I have a smilar case as teo1978. - I have a dell laptop with Optimus
technology with both Intel and Nvidia GPU.

Before the upgrade from 331 to 340 I never managed to get the Nvidia GPU
running, so I just used Intel instead. After the upgrade, the Nvidia GPU
was turned on by default but something was wrong with the configuration
in the xorg.conf file. Because of this I got a black screen after
rebooting.

The solution that I linked a few posts up actually has a thorough
explanation of what happened. It shows how to fix the xorg.conf file and
how to prevent ubuntu from changing it back after reboot (it was crucial
for me).

After all that my laptop started to actually use the Nvidia GPU for both
daily use and manually running simulation on GPU.

Bug description:
  Filing this against the 340-updates version but possibly the same
  applies to older versions, too. The nvidia source package produces two
  individual dkms packages: nvidia-340-updates, nvidia-340-updates-uvm.
  The problem is that the DKMS build of the nvidia-uvm module runs
  compile steps inside the nvidia modules build directory. This is
  violating the DKMS assumption that each module can be build
  independently (there is no way of describing cross-modules
  dependencies and even more important, the autoinstall step after a new
  kernel is installed will run the modules build in parallel).

  Since nvidia and nvidia-uvm are very dependent on each other the right
  course of action seems to be to combine both sources in one DKMS
  module that produces two kernel modules (this is supported by DKMS).
  For the transition this resulting dkms package needs to have a
  breaks/replaces for the nvidia-uvm package.
