Public bug reported:
We have an environment where several users use different languages but
share machines which use LDAP/Kerberos/NFS. In the previous LTS, the
default display manager (GDM) provided a menu which would allow setting
the language to use for a session, and would remember the previous
setting (using ~/.dmrc). This appears to no longer work with lightdm in
12.04, and no menu is provided by default. However, a menu can be
enabled for lightdm-gtk-greeter (1.1.4-0ubuntu1). Unfortunately, the
language choice doesn't get used. I have the same problem if
accountsservice (0.6.15-2ubuntu9) is enabled or not.
The following is logged by lightdm when using accountsservice:

I understand that the new place for the language to be stored is in
~/.pam_environment, but the file does not get touched, rather ~/.dmrc
does.
