Sometimes, the desktop environment of elementary OS Loki failed to start when i've entered my password in LightDM.

Do you have any tips for me ?

Thx for read this post.

  • You should read the last lines of file /var/log/syslog to see if you can find anything strange there. You can do it from the GUI or tail /var/log/syslog. Opening a terminal with Ctrl+Alt+F2 (before entering your password in GUI) logging in terminal and using top can also help. Afterwards come back to GUI with CTRL+ALT+F7 enter your password in GUI and come back again to terminal with CTRL+ALT+F2 to see if you can determine the cause of this problem. You can alternate between GUI and terminal. NOTE: I use F2 but you can use F3, F4... Oct 22, 2016 at 23:17

This technique is work for me:

  1. Open "Files" application as root
  2. Browse folder: /etc/xdg/autostart/
  3. Rename file: at-spi-dbus-bus.desktop to at-spi-dbus-bus.disabled
  4. Restart

I can confirm that renaming /etc/xdg/autostart/at-spi-dbus-bus.desktop to /etc/xdg/autostart/at-spi-dbus-bus.disabled fixed the issue for me as well.

    It might be easier to provide a single console command which can do this in one go instead of opening Files as root (which is not terribly safe).

I'm curious if your desktop failed to start, or maybe it hung for a long time. (long time = 2-3 or more minutes)

On 3 different installs, I've seen this problem happen after installing the latest system updates.

On all of them, I solved the problem by going to terminal and running this:

sudo mv /etc/xdg/autostart/at-spi-dbus-bus.desktop /etc/xdg/autostart/at-spi-dbus-bus.disabled

You should pay attention to this:


It's a know bug, isn't solved yet but its on work :D
