Title:
  Black screen after switching to UEFI boot and prime-select nvidia.

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Note that this issue is reproducible on two computers, both running a
  fresh install from Xubuntu 16.10. Also, everything was running fine on
  both computers until recently. Also, running the Nouveau driver works.

  When installing any recent version of the nvidia driver (I tried with
  the 367 and 375 from vanilla repos, then the 375 and 378 from the
  graphics-driver PPA), I cannot get lightdm to start if `prime-select
  nvidia` is issued and rebooted. The screen is black with an artifact
  of a cursor on the top left screen (But it's not blinking, I think
  it's just a video frame being displayed and not updated at all).

  I experimented using various settings, and also installed bumblebee to
  diagnose. I got the nvidia GPU to work in some circumstances using
  `primusrun` and `optirun` so I know the card function on both
  computers.

  I'm not sure what to include in this bug report, the logs are rare and
  don't show very much information.

  A bit of interesting fact, is that since the problem is showing the regular 
XFCE compositor has VSync correctly on the intel card (Is it related?).
  Another interesting fact, is that since the problem is showing, having 
compton's `glx-no-rebind-pixmap` set to true makes menus not appear in 
chromium-based applications (Is it related?).

  
  Also, but I'm not sure: it might be since I've switched to UEFI boots.

  Not sure what else to include in this report, please advise.
