LightDM needs dbus running? If doing:

root #rc-update add xdm default

Also need to have done:

lightdm user account setup

Talk status
This discussion is still ongoing.

Lightdm will allow XDMCP users to reboot and shutdown the host prior to logging in, unless lightdm is run under a different account to root. Here's some instructions on how to set it up under an account called 'lightdm'.

To create the system account use the following command:

root #useradd -r -d /var/lib/lightdm-data/lightdm -s /bin/nologin lightdm

Then modify lightdm.conf so that it has the following entry in the [LightDM] section:

As a first time Gentoo user, it took me a long time to find this lightdm user account setup. It would be nice if this was on the wiki page. I was wrestling with errors thinking something was wrong with xdm and and all I had to do was add a user for lightdm.

ebuild should do this, but no bug #563564 --Cronolio (talk) 12:56, 3 April 2018 (UTC)
I completely agree with Cronolio , this is a step the ebuild should perform, just as SDDM creates the sddm user at install time. I'll see if I can elevate this. For the present, it is good to add this information to the wiki page since it's a Gentoo-specific setup instruction until bug #563564 is closed. --Maffblaster (talk) 22:54, 3 April 2018 (UTC)

gnome-keyring section needs updating

Talk status
This discussion is still ongoing.

The current instructions for adding gnome-keyring support using pam have proven insufficient on my system booting into openbox. The pam file shipped with lightdm is different from listed, but I don't know if that's really a concern. Here's the current shipped:

FILE /etc/pam.d/lightdm
auth	substack		system-local-login
account	substack		system-local-login
password	substack		system-local-login
session	substack		system-local-login

I won't edit the page myself because I haven't yet found a solution. gnome-keyring runs as a daemon but I'm still prompted for the password on starting up an app that needs it. It'd be great if someone who got this working recently could offer the steps they used. --Tephra (talk) 18:20, 19 July 2021 (UTC)
