I too have the error displayed in the original bug. I intentionally waited a good few seconds before logging in to help with the log timestamps, my machine boots in ~3-5 seconds. No matter how long I wait after boot before logging in, it always takes the same time to show the desktop.
My login delay appears to be at this point. Jan 12 20:53:53 Freyja rtkit-daemon[1975]: Successfully made thread 2798 of process 2798 (n/a) owned by '1000' high priority at nice level -11.

Just before all this, there is a lot of logging from gdm-x-session "configuring" my displays or something. Those ~200 lines of gdm-x-session occur within about a 2 second period (not much), just before this delay seen here. To my untrained eye it's hard to see where the log relates to the login delay, but if it looks like As with yolen, I am also running "high res" displays, 3 x 3840x2160, 2 x DP, 1 x HDMI and the Nvidia drivers and related hog a good proportion of the log. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-session in Ubuntu. https://bugs.launchpad.net/bugs/1736011 Title: CRITICAL: Unable to create a DBus proxy for GnomeScreensaver: Error calling StartServiceByName for org.gnome.ScreenSaver: GDBus.Error:org.freedesktop.DBus.Error.Spawn.ChildExited: Process org.gnome.ScreenSaver exited with status 1 Status in gnome-session package in Ubuntu: Confirmed Bug description: That error is logged: gnome-session[895]: gnome-session-binary[895]: CRITICAL: Unable to create a DBus proxy for GnomeScreensaver: Error calling StartServiceByName for org.gnome.ScreenSaver: GDBus.Error:org.freedesktop.DBus.Error.Spawn.ChildExited: Process org.gnome.ScreenSaver exited with status 1 oem@ubuntu:~$ localectl System Locale: LANG=en_US.UTF-8 VC Keymap: n/a X11 Layout: fr X11 Model: pc105 X11 Variant: oss So, with googling help (https://bbs.archlinux.org/viewtopic.php?id=180103), i've edited /etc/locale-gen (as user) and uncommented the line: fr_FR.UTF-8 and then ran 'sudo locale-gen' and finally rebooted.
