Public bug reported:
Summary:
I have installed Ubuntu 14.04 on a number of machines and set them to
use kdm as the display manager. This works fine except for when a user
attempts to log in to a Gnome session. The greeter just disappears and
nothing happens.
The user is authenticated according to auth.log:
May 30 09:35:42 machine kdm: :0[2302]: pam_krb5(kdm:auth): user user
authenticated as user@DOMAIN
May 30 09:35:42 machine kdm: :0[2302]: pam_unix(kdm:account): unrecognized
option [ignore_root]
May 30 09:35:42 machine kdm: :0[2302]: pam_unix(kdm:session): session
opened for user user by (uid=0)
But there's not a lot of Gnome processes running.
root@machine:~# ps -fu user
UID PID PPID C STIME TTY TIME CMD
user 2346 2302 0 09:35 ? 00:00:00 init --user
user 2419 2346 0 09:35 ? 00:00:00 ssh-agent -s
user 2424 2346 0 09:35 ? 00:00:00 dbus-daemon --fork
--session --address=unix:abstract=/tmp/dbus-B6YOSxHnPA
user 2430 2346 0 09:35 ? 00:00:00 upstart-event-bridge
user 2432 2346 0 09:35 ? 00:00:00 upstart-file-bridge
--daemon --user
user 2434 2346 0 09:35 ? 00:00:00 upstart-dbus-bridge
--daemon --session --user --bus-name session
user 2436 2346 0 09:35 ? 00:00:00 upstart-dbus-bridge
--daemon --system --user --bus-name system
The Gnome session works fine when using lightdm.
1. lsb_release -rd:
Description: Ubuntu 14.04 LTS

3. Expected result:

visible.
