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". Bug #1663839 (reported against 17.04) seems similar, as does bug #1731428 (reported against 17.10). journalctl output during the issue: Apr 16 07:00:30 saegusa gnome-session[4342]: gnome-session-binary[4342]: WARNING: Application 'org.gnome.SettingsDaemon.Color.desktop' failed to register before timeout Apr 16 07:00:30 saegusa gnome-session-binary[4342]: WARNING: Application 'org.gnome.SettingsDaemon.Color.desktop' failed to register before timeout Apr 16 07:00:30 saegusa gnome-session-binary[4342]: Unrecoverable failure in required component org.gnome.SettingsDaemon.Color.desktop Apr 16 07:00:30 saegusa gnome-session[4342]: gnome-session-binary[4342]: CRITICAL: We failed, but the fail whale is dead.
