GDM crashes at system boot, but starts after gdm.service reboot

I've come across a strange behavior with starting gdm.service at system startup.
After my computer's been rebooted, the gdm.service crashed with a coredump of 'gnome-shell'.
This is journalctl output:

Re: GDM crashes at system boot, but starts after gdm.service reboot

Hi,
I notice a quite similar behavior.

GDM crash at boot but i am not able to switch tty.

Downgrade libsystemd and systemd "fix" the issue.

[2018-07-06 17:05] [ALPM] downgraded libsystemd (239.0-2 -> 238.133-4)
[2018-07-06 17:05] [ALPM] downgraded systemd (239.0-2 -> 238.133-4)

Downgrading helped, but in my journalctl there is still a coredump.
It's seems to me, there is no relation between the bug with systemd and the gnome-shell coredumped

Re: GDM crashes at system boot, but starts after gdm.service reboot

I seem to be having a similar issue today on my desktop, but had to leave for work before I could do any real troubleshooting, I'll have to look into this when I get home. Thanks.

Same here, couldn't switch tty so had to ssh in and downgrade systemd.
The coredump is also still present - issue with 'libmutter-2.so.0' ?

Yes, the stacktrace ends with

Re: GDM crashes at system boot, but starts after gdm.service reboot

Reporting in with the same problem. Seeing the same core dump messages in my logs with gdm never starting. Downgrading systemd back down fixed the problem for now, but I can't seem to figure out what might be going on.

Re: GDM crashes at system boot, but starts after gdm.service reboot

Same issue with me on a fresh install.
The issue only seems to occur with the nvidia or nvidia-dkms packages installed.
Uninstalling these 'resolves' the problem for now.

Reinstalled the nvidia package and just switched to lightdm until the issue with gdm is fixed.

Re: GDM crashes at system boot, but starts after gdm.service reboot

Same issue here. Booting with the LTS kernel works around it for me.

Does anyone know if this is reported somewhere?

Re: GDM crashes at system boot, but starts after gdm.service reboot

From a glance this reads like a simple race condition, does enabling early KMS help?

Thanks for this advice. I just tried that, doesn't solve the problem.

Re: GDM crashes at system boot, but starts after gdm.service reboot

The recent update to linux 4.17.4-1 and nvidia-dkms 396.24-14 seems to have helped. I can load gdm and log into gnome, but I still see the same core dump messages in the journal.

EDIT: Scratch that. Seems like it doesn't happen at every boot, just usually. Booting with the LTS kernel doesn't solve it either, I just happened to get away with it a couple times earlier.

I got the same issue, and could only work around the issue by reinstalling nvidia as well as switching to lightdm from gdm.

Re: GDM crashes at system boot, but starts after gdm.service reboot

Alright so I'm having the same issue, I'm also unable to switch tty. I don't have ssh setup on this machine, I also don't have a disk drive in it anymore, and my laptop is down (for other reasons) so I don't have a machine to create an arch installer with... haha...  Any ideas?

I'm about to dig through some older flash drives and hope one has a bootable distro (hopefully arch) on it...

Man, it's been a while since I've had to use installation media to restore my system... I've had the same install on this system for 4 years now since I built this computer...

You should be able to get into a "terminal mode" by adding a kernel parameter at boot, I don't currently remember which one.

Re: GDM crashes at system boot, but starts after gdm.service reboot

Here's a hint which may help. Edit /etc/gdm/custom.conf and _UNCOMMENT_ the line with "WaylandEnable=false", thus disabling Wayland (which does not work with nvidia drivers anyway). For me this solved the issue of gnome-shell crashing at startup. I yet have to check whether it will still work with most recent systemd/libsystemd - yesterday I had to downgrade to "fix" the problem, so at this very moment I'm using version 238. However my brother (who has almost identical PC with almost identical system) reports no problem when "WaylandEnable=false" line in mentioned file is uncommented.

I've reported this bug yesterday too -> https://bugs.archlinux.org/task/59262 (;

Re: GDM crashes at system boot, but starts after gdm.service reboot

Thanks Freddie! Uncommenting "WaylandEnable=false" works fine for me, and I have installed systemd/libsystemd 239.

In case you are using GRUB, make sure GRUB_DISABLE_RECOVERY is set to false in /etc/default/grub to create a recovery mode option in your boot menu. See also the GRUB#Additional_arguments at the wiki.
