This seems to be similar to #100, but the backgrounds directory is readable (and the background is working when the system eventually relaunches the greeter and it does not segfault).

Any ideas?

In addition to this coredump I am getting CRITICAL: g_object_unref: assertion 'G_IS_OBJECT (object)' failed in /var/log/lightdm/lightdm.log

gberdzenishvili commented 6 years ago

Not sure it this affects anything but it looks strange:

[+0.00s] DEBUG: Loading configuration from /etc/lightdm/lightdm.conf
[+0.00s] DEBUG:   [LightDM] contains unknown option session-wrapper

Found it in /var/log/lightdm/lightdm.log

Seat configuration is matched against the seat name glob in the section, for example:

[Seat:*] matches all seats and is applied first.

[Seat:seat0] matches the seat named "seat0".

[Seat:seat-thin-client*] matches all seats that have names that start with "seat-thin-client".

I'm having the same issue intermittently which causes lightdm to crash and send me to the login screen
