I have a Dell Latitude E6520 with Nvidia Optimus graphics:
I have disabled Optimus in the CMOS Setup:

Optimus has (finally) become natively supported by the
Proprietary NVIDIA driver recently (it's just a matter of
running an application the environment variable
__NV_PRIME_RENDER_OFFLOAD set to 1 and that process will use the
dGPU).

If you can afford to reinstall the machine: change the option back
above. Do an expert text mode install which should work using basic
graphics. Do _NOT_ install a desktop environment or anything much
more than a> bare text mode only system. Finish the install. Reboot.
At that point, install the proprietary drivers. Then, and only then,
use tasksel to install a desktop environment which will pick up the
Nividia proprietary driver and use that to drive the desktop.
If nouveau is installed, you then have a significant problem
installing the proprietary drivers hence the suggestion to
re-install. I found this out the hard way with a laptop a little
while ago that was using Optimus :(
As they say -- "there is no substitute for experience".
That sounds like a viable work-around. Thank you. :-)
