[Bug 31144] GNOME fails to start up for new user

[Chris Moore]

Public bug reported:
https://launchpad.net/malone/bugs/31144

Affects: gnome-session (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed

Description:
I created a new user:

$ sudo adduser tmp2

Then tried to run GNOME as that user.

After entering the username and password at the GDM login screen, the
whole screen went a kind of "steel blue" colour (not the traditional
ubuntu brown) and stayed like that.  No GNOME splash screen, no panels,
no nothing.

This is with a completely clean user account.

I then tried adding the new user to all the groups that my own user is
in (adm, audio, etc, etc), but it made no difference.

The file ~tmp2/.xsession-errors contains the following:

---------------------------------

(process:2767): Gtk-WARNING **: This process is currently running setuid or setgid.
This is not a supported use of GTK+. You must create a helper
program instead. For further details, see:

/etc/gdm/PreSession/Default: Registering your session with wtmp and utmp
/etc/gdm/PreSession/Default: running: /usr/bin/sessreg -a -w /var/log/wtmp -u /var/run/utmp -x "/var/lib/gdm/:0.Xservers" -h "" -l ":0" "tmp2"
/etc/gdm/Xsession: Beginning session setup...
SESSION_MANAGER=local/chrislap:/tmp/.ICE-unix/2764
---------------------------------

but then, the same warning appears at the top on my own ~/.xsession-
errors so it probably isn't relevant.  I'll post a list of 'tmp2's
processes in a follow-up comment.
