No option to disable hostname

This is in the greeter right? Reassigning..

lp:~robert-ancell/unity-greeter/show-hostname contains a proposed fix for this. To disable the hostname do:

$ sudoedit /usr/share/glib-2.0/schemas/50_unity-greeter.gschema.override
and set to:
[com.canonical.unity-greeter]
show-hostname = false
$ sudo glib-compile-schemas /usr/share/glib-2.0/schemas/

Hi Robert,

Thanks! In which Ubuntu version will this be implemented? 14.04? We're
currently using 12.04.

Two more questions. The dir /usr/share will be overwritten with
software upgrades right? Is there also a static place to put these
settings? For example: /var/lib/polkit-1/localauthority/50-local.d/?

And is there also a way to list all the possible settings? Or are all
the settings that are possible also in /usr/share/glib-2.0/schemas/?
But if there is a command to list all settings then I'm all ears.
Thank you again.

Kind regards,
Kees

No, the ".override" file will be preserved across upgrades. You can ship/provision that package in a file.
Alternatively you can modify the settings for the lightdm user directly like so:

$ sudo -i
$ xhost +SI:localuser:lightdm
$ su lightdm -s /bin/bash
$ gsettings set com.canonical.unity-greeter show-hostname 'false'
$ xhost -SI:localuser:lightdm
