Subject: gdm3 fails with the "Oh No! Something went wrong" message with Xephyr and vncserver

Date: Sat, 30 Nov 2013 13:09:18 +0100

Package: gdm3
Version: 3.8.4-6
Severity: normal
Tags: upstream

Dear Maintainer,
*** Please consider answering these questions, where appropriate ***

gdm3 works well on a real display. However I get the "Oh No! Something went
wrong" message when I use it with Xephyr or vncserver.
(I use GDM 3.8.4)

To get the problem:
1) edit  /etc/gdm3/daemon.conf  to add
        [xdmcp]
        Enable = true
2) then do:
   Xephyr -query localhost :1

Best regards
Christophe
