Created attachment 139089
  --> https://bugs.freedesktop.org/attachment.cgi?id=139089&action=edit
full journal of previous boot

Hangs on boot with small cursor in top left of screen.  No power changes seem
to help - only nomodeset and nouveau.nofbaccel (which seems to just turn off
nouveau).  Journal indicates it is just a graphics hang. Trying VTs has no
effect.

GTX 1050] (rev a1)
Software:
OS: Ubuntu 18.04 - also similar results with stock 18.04 and Fedora 28 beta
Mesa: 18.2.0 git from oibaf PPA
Kernel: 4.17.0-041700rc2-generic from Ubuntu Mainline PPA
xserver-xorg-video-nouveau: 1.0.15-2

--- Comment #1 from Ilia Mirkin <imirkin at alum.mit.edu> ---
GPU lockup right on boot. nofbaccel makes fbdev not accelerated (and noaccel=1
makes userspace not able to access the accel features), so the gr unit is never
used. The GPU is still used, but only for outputs.

Perhaps PCIe PM is getting in the way? You could try killing it with
pcie_port_pm=off although that hasn't helped a lot of people.

You could try adding nouveau.runpm=0 although since the hang is right on load,
I doubt that would affect matters.

Thanks for the suggestions, they didn't appear to have an impact.
