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'.

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)
