Bug description:
This is to track
https://bugzilla.gnome.org/show_bug.cgi?id=787207 " gdm & nvidia with
modeset=1 causes loop, does not launch greeter "
I don't know if this is an nvidia bug or a gdm3 bug but it requires
both to reproduce.

Created attachment 359016 [details]
syslog
reproduced on two Thinkpad laptops with bios set to Discrete graphics.
In this mode, the integrated Intel graphics is bypassed by a hardware
mux and the machines appears to have only Nvidia graphics.
Environment is Ubuntu 17.10 development version, pre-release packages
One laptop has Quadro 1000M, the other Quadro M1000M. Both cards are
supported by the latest Nvidia drivers.
Nvidia driver 375 or 384 (as packaged by Ubuntu)
/etc/modprobe.d/zz-nvidia.conf has
options nvidia_384_drm modeset=1
and after that setting
sudo update-initramfs -u
This problem does not occur when
lightdm is used in instead of gdm3
or
modeset=1
is not deployed.
The session attempted to launch is either gnome or the new "ubuntu"
desktop session, which is gnome
The boot process fails.Sometimes there is just black screen (and high
CPU activity driving the fans) and sometimes there is a message about
NVIDIA persistence daemon starting and stopping, as well as gdm
messages.
I mounted the filesystem after a crash, and I attach syslog.
In the attached syslog, search for persistenced to see messages like
