[Bug 1262068] Re: nvidia-prime should support gdm also

 

Since a recent update on ubuntu-drivers-common and nvidia driver I am
unable to select the NVIDIA GPU through nvidia-settings. When I try to
do so, all I obtain is a blank dialog box with a forbidden sign and an
'OK' button.

Before this update I was using the packages provided by ppa:darkxst/gdm-
prime.

Reading the comments above, I have edited the /etc/init/gpu-manager.conf
file to add the 'or starting gdm' option but it did not change anything.

What can I do ?

Bug description:
  On Ubuntu GNOME we ship gdm by default, however nvidia-prime depends
  on lightdm. This means that

  1. Anyone installing nvidia binary drivers will pull in nvidia-prime and subsequently lightdm. As a consequence of this they are also going to get the potentially confusing dconf pop-up asking them to choose a DM.
  2. nvidia-prime probably won't work when using gdm

  I haven't looked to closely at how deeply integrated this is with
  lightdm, however we particularly don't want #1 happening, and it would
  be nice if #2 worked.
