Configuring and using Xdmcp with gdm3 on ubuntu 18.04
On a fresh minimal ubuntu 18.04 installation, I tried to activate and use the gdm3 xdmcp server.
Here are steps I followed:
- 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 ?
Thanks for your help.

In case soemone else finds this question and has problems getting XDMCP to work with gdm3, I managed to get it working by setting gdm3 to use xorg instead of wayland.
/etc/gdm3/custom.conf
[daemon]
# Uncoment the line below to force the login screen to use Xorg
WaylandEnable=false
