Specs

Display Manager: lightdm 1.30.0

Desktop Environment: gnome 3.36.3 (though I also tried xfce)

Problem/Background

Once I login, all I can see (for at least a minute) is the wallpaper and mouse. Eventually the rest of the desktop environment is loaded and everything is good to go. If I log out and back in, I don't have the same issue I do at startup. Additionally, I can't use a tty to find out what is going on because login to the tty takes forever - perhaps a related problem (authentication)?

Originally I thought the problem was lightdm but it turns out if I switch to gdm3 I have the same problem except instead of seeing the walpaper and mouse I just have a black screen. I am now convinced the problem lies in the GNOME DE.

Attempts

  • Installation of haveged
  • Disabling of the lightdm.service and startxing
  • Disabling/removal of gnome extensions
  • Installation/use of gdm3
  • Installation/use of xubuntu-desktop
  • Use of both NVIDIA proprietary and nouveau video drivers
  • Upgrading to 20.10 Groovy Gorilla (trying this currently - will update if works/doesn't)

Logs [EDITED]

I took a more targeted approach and as soon as I entered my login credentials around 15:06:20, I timed the duration to DE initialization (~58s). All logs below are taken from journalctl in that timeframe and the first three are tailored to a specific category.

Note my mileage varies with critical-chain i.e. sometimes these processes (the ones with +<time>) add up to less than a few seconds. That is, the networkd-dispatcher does not normally take that long to initialize.

The PAM errors are indirectly coming from /etc/pam.d/lightdm:

Have you tried looking at Settings Manager -> System (section) -> Session and Startup -> Advanced (tab) - I've got my "Launch KDE services at startup" disabled.

Also on the "Application Autostart" it might list kwallet or other KDE items. I have a minimalist selection of gnome/kde items - all gnome except "SSH Key Agent (GNOME Keyring: SSH Agent)" and "GNOME settings override migration" are not checked, and nothing KDE releated.

  • Looks like Settings Manager is the "Graphical Settings Manager for Xfce 4" - I am using GNOME and don't seem to have that option in my settings. However I don't see any non-GNOME entries in my startup applications Aug 24, 2020 at 22:18
  • Ah - didn't realise you were using Gnome. Could try creating a new user and see if that has the same issue. Or switch to xfce4 :-) Aug 24, 2020 at 22:23
  • didn't have any better luck with xfce4 - so maybe not the Desktop environment after all... but it is 100% something between the DM and the DE Aug 27, 2020 at 20:31

Disable networkd-dispatcher

From Reddit:

Disable networkd services:

If you are not a system admin you don't need this. Gui uses network-manger (and it has it's own dispatcher) anyway.

sudo apt-get remove networkd-dispatcher
sudo systemctl stop systemd-networkd.service
sudo systemctl disable systemd-networkd.service

There are other boot speed tips but this appears most relevant to your case.

Bug Report

There is a bug report on your issue:

It seems to have begun with 20.04 as 16.04 doesn't seem to have the problem:

$ ll /etc/securetty
-rw-r--r-- 1 root root 4038 Mar 29  2016 /etc/securetty

You should subscribe to the bug report and follow progress.

  • I do get that error in journalctl but the bug doesn't say anything about a login delay - maybe I'll provide my experience there and hope it is related Aug 31, 2020 at 19:47
  • @SterlingButters can you run systemd-analyze blame and include output in your question? Aug 31, 2020 at 23:28
  • Happy to - please see EDIT. Sorry for late response Sep 1, 2020 at 1:50
  • Per comment thread on that bug: > Would this bug cause a gnome-session initialization delay? No, it would not. The sum totality of the impact of this bug is the extra warning messages in the log files. Sep 1, 2020 at 13:58
  • @SterlingButters Thanks for the systemd timings, I've updated answer with some tips. Sep 1, 2020 at 14:58
