[Bug 1777378] Re: GDM no longer presents GUI login Ubuntu 18.04

2018-06-18 Thread Daniel van Vugt 
However maybe the make.log won't help. Because you appear to have a
working kernel driver.

I can also see this failure, which is important:

Clutter: Unable to initialize the Clutter backend: no available drivers found.

which would/should be related to:

2018-06-17 Thread Daniel van Vugt 
Thanks.

Comment #14 indeed shows you ran into a lot of trouble on 2018-06-15 and
tried a lot of things to fix the nvidia drivers. The only thing is that
the nvidia drivers have never changed at all since their release in
April:

  https://launchpad.net/ubuntu/+source/nvidia-graphics-drivers-390

So Nvidia updates can't be the issue.

Something that did happen just before the problem began was a kernel
upgrade:

  https://launchpad.net/ubuntu/+source/linux/4.15.0-23.25

So that will have necessitated a rebuild of the nvidia kernel driver,
which might have failed and would explain the issue. So...

  1. Can you find any log or text files under /var/log/dkms ?
  2. Can you please run 'lspci -k' on the machine and send us the output?

[Bug 1777378] Re: GDM no longer presents GUI login Ubuntu 18.04

2018-06-17 Thread William S Gregory 
Noticed previously that the status of my working Gnome (Ubuntu 16.04)
desktop's GDM3 service is a bit different than the bugged machine.
Attached is a series of systemctl status updates before and after
stopping and starting the GDM3 service. Note that I did not run any
other systemctl command against GDM3 since the last reboot for this
output.

There seems to be differences in opening and closing sessions involving
PAM. My working system starts a PAM session and leaves it running. In
the non-working system it appears that GDM ends the session shortly
after opening it, and some child processes have died right away as well.

Manually installed files specified in #12. There was one missing
package, "libglib2.0-dev". Installed it, then ran "dpkg -i *.deb" again.
Rebooted. No apparent change on first reboot. No apparent change after
second reboot.

Another thought is that there was a gdm3 update on 12 June that might
have taken a couple of days to reach you. If that has caused the problem
then it would be a good idea to try downloading and reinstalling the
prior version's files from here:

https://launchpad.net/ubuntu/+source/gdm3/3.28.0-0ubuntu1/+build/14516225

Download the .deb files from there, then install them manually by
running:

  dpkg -i *.deb

Daniel, I am not sure what to do with apport-collect 1777378 from #3,
since it is waiting in vein for a web-browser to open. This won't happen
since I have no GUI desktop at present.

I did try the fix from #5 two different ways:

1> Commented out "WaylandEnable=true" with a leading #.
   -This yielded the same problem. A boot to a seemingly hung tty1. Can still 
use other terminals and SSH normally. 

2> Changed line in question to read "WaylandEnable=false".
   -This boots to no useable terminals. Have to SSH in to do anything.

[Bug 1777378] Re: GDM no longer presents GUI login Ubuntu 18.04

2018-06-17 Thread Daniel van Vugt 
Also, your change to /etc/gdm3/custom.conf is likely to make it
incompatible with the Nvidia driver:

  WaylandEnable=true

Which would explain the lack of GUI.

Please try undoing that change and reboot.

Great. Next please attach output from these commands (run on the affected 
machine):
  dmesg
and
  journalctl -b

You can save their output by running:
  dmesg > dmesg.txt
  journalctl -b > journal.txt
and then copy the files to/from another machine via 'scp'.

Please also let us know if the machine has any files in /var/crash/ and
what they are.

** Changed in: gdm3 (Ubuntu)
   Status: New => Incomplete
