This bug was fixed in the package gdm3 - 3.25.90.1-0ubuntu4

gdm3 (3.25.90.1-0ubuntu4) artful; urgency=medium

  [ Jeremy Bicha ]
  * Don't build for s390x since gnome-shell isn't available there

  [ Iain Lane ]
  * We only need to do the above for gdm3 itself. This will make future
enablement a bit easier; maintaining arch lists is error prone.
  * debian/rules: Only do gdm3 things when we're building gdm3.

What's the bug report for hybrid systems? I can't get gdm working with
modeset=1 (aiming to get PRIME sync working). Is good in lightdm. There
are so many bug reports with similar symptoms.

2017-07-14 Thread Alberto Milone 
@Doug: we are going to leave PRIME systems alone in any case. This bug
report is about non hybrid systems. You are using the intel GPU to drive
the screen, and that is why X11 + KMS works for you. As far as I know,
Wayland doesn't support that yet.

Absolutely isn't broken, at least here with a hybrid(optimus) device.
To re-confirm just did fresh install from iso of a couple of days ago.
Updated that install fully today.
Installed nvidia drivers (375
rebooted
Enabled KMS via nvidia-graphics-drivers.conf
sudo update-initramfs -u
Rebooted to default session, works fine inc. the added bonus of PRIME 
Synchronization: 1 on primary display.

And as mentioned any attempt to log in to a gnome-wayland session fails 
with login loop.

Doug, are you saying that what Alberto is saying - that X11 sessions
with KMS enabled on Nvidia is broken - isn't right?

Maybe the two of you could look into that together.

[Bug 1697882] Re: GDM should not allow X11 sessions when NVIDIA's KMS is enabled

2017-07-10 Thread Doug McMahon 
Just to reiterate, scorecard here on  i7-4700MQ, GeForce GT 755M,
nvidia-375.66 drivers,  prime profile of nvidia selected.

gnome-wayland session, gdm, KMS = total fail
gnome-wayland session. gdm = total fail

default (ubuntu) session, gdm KMS, = all good, happy days, PRIME 
Synchronization = yes
default (ubuntu) session, lightdm, KMS = all good, even happier days, PRIME 
Synchronization = yes

So just the opposite of what is stated here & elsewhere, i.e. Will Cooke
-

"While Wayland requires KMS (kernel mode setting) to be enabled, there is
a current limitation in the nvidia driver that causes X11 sessions to
crash with KMS. For this reason I am keeping KMS disabled by default, at
least for now. This is not going to be fixed anytime soon, as it
requires major changes in the driver.

Users who want to try Wayland with nvidia will have to set modeset=1 in
/etc/modprobe.d/nvidia-graphics-drivers.conf, and then update the
initramfs.

When KMS is enabled, GDM will start, but entering the default session
will fail with no error that is visible to the user. Ideally, I think we
would check if KMS is enabled with nvidia, and either show only the
Wayland sessions or maybe simply
default to the Wayland session."

Actually stand corrected, after a couple of restarts PRIME Synchronization is 
now working.
So until you all can provide nvidia thru Wayland X11 sessions Should be 
allowed..

Don't see it crashing X11 session here at all, 17.10 -
$ echo $DESKTOP_SESSION

sudo cat /sys/module/nvidia_drm/parameters/modeset

So currently - 
no nvidia support in gdm3/wayland
nvidia support in gdm3/xserver-xorg but no PRIME Synchronization support.
i.e., a complete fail in Ubuntu all around
