Public bug reported:

It seems whenever I try to run `prime-select nvidia` I get a blank
screen after the splash screen. When I am running under `prime-select
intel` - I have no problems.

I triple boot, two of them being Ubuntu (one for testing one for every
day use), and the problem seems to lie only on the every day use one.
Both have 16.04 (except the main one got upgraded from 14.04, and the
testing one from 15.10). Both have the same version of nvidia
(`nvidia-361`). Both seem to have the same configuration. Yet the one I
want it to work on does not work.

I am more than happy to provide any logs needed of both installs to help
diagnose. From what I have seen so far, /etc/X11/xorg.conf are identical
on both.

3) I expected to be able to see the lightdm screen after running in
nvidia mode (prime-select nvidia).

4) I see nothing on the screen, but I hear the Ubuntu boot sound
notifying me that the login screen is there. Also, if I type my password
in I can hear my hard drive spin up and the LED blink - telling me that
clearly something is happening.
