OS: Ubuntu 18.04 LTS x86_64
uname: Linux 4.15.0-46-generic x86_64
After performing automatic update of OS about 10 days ago (1-MAR-2019
and later) boot process shows with grub option "quiet splash" following
lines
[ OK ] Started Set console scheme.
<other entries>
[ OK ] Starting User Manager for UID 121...
after few moments the graphical login screen is shown up and OS can be used
without limitations.
after succesful login a message box come up that there is a problem with a
system application with tion to generate a message to be sended.
syslog shows
Mar 13 14:39:16 <machine> gdm3[2095]: error: unexpectedly disconnected from
boot status daemon
Mar 13 14:39:16 <machine> systemd[1]: Started Set console scheme.
So it looks like gdm3 terminated for unknown reason and restarts or
reconnects

/etc/gdm3/custom.conf
