Configuring and using Xdmcp with gdm3 on ubuntu 18.04

• Installation

I used the normal installation.

"Download updates during installation" was checked

"Install 3rd parties for Gfx/Wifi/.." was not checked.

• Xdmcp server

1 . Edit /etc/hosts.allow to set (cf. Gnome doc.).

ALL: ALL #Wide opened to be sure the problem isn't here

2 . Edit /etc/gdm3/custom.conf to set:

[security] DisallowTCP=false [xdmcp] Enable=true

3 . Restart gdm

sudo /etc/init.d/gdm3 restart

• Xdmcp client

sudo apt install xnest Xnest -query localhost -geometry 1024x768 :1

Unfortunately, I only have a black screen with regular white flash.

Where did I do something wrong ?
