Fix: If you search your journalctl output and find an event like this: Jul 07 20:45:20 ubuntu dbus-daemon[1064]: [system] Activating via systemd: service name='org.freedesktop.ColorManager' unit='colord.service' requested by ':1.168' (uid=1000 pid=23634 comm="/usr/lib/gnome-settings-daemon/gsd-color " label="unconfined")
and the timestamp coincides with the second (successful) login (look for "GNOME Shell started" if you are using Gnome), and the first (failed) login doesn't have a matching event like the above, then the following might help: # copy /lib/systemd/system/graphical.target to /etc/systemd/system/ # edit /etc/systemd/system/graphical.target, so that when you diff it against the original, you get something like this: $ diff /lib/systemd/system/graphical.target /etc/systemd/system/graphical.target 14c14 < Wants=display-manager.service --- > Wants=display-manager.service colord.service 16c16 < After=multi-user.target rescue.service rescue.target display-manager.service --- > After=multi-user.target rescue.service rescue.target display-manager.service > colord.service # next time you reboot the issue should be gone. Explanation: gsd-color is invoked by org.gnome.SettingsDaemon.Color.desktop. The event above is logged presumably when gsd-color requests the dbus service provided by colord.service. One can reasonably guess a failed login happens when gsd-color makes the request but colord hasn't yet started, so it fails and when gnome shell gets tired waiting, it kills itself. So we add colord as a dependency to be run prior to graphical.target. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-settings-daemon in Ubuntu. https://bugs.launchpad.net/bugs/1764417 Title: Unrecoverable failure in required component org.gnome.SettingsDaemon.Color.desktop Status in gnome-settings-daemon package in Ubuntu: Confirmed Bug description: I've had this happen a couple of times now since upgrading to 18.04: soon (perhaps within a minute) after logging in, Gnome session ends abruptly and I'm thrown back to the login screen. IIRC, in both instances this occurred on the first login after boot, so it does not reoccur on the subsequent re-login, and not on every login (very rarely in fact), and for now I have no better steps to reproduce this other than "boot, log in".
