[PATCH] feature request for a greeter string

[Morty]

I'd like to submit an enhancement/merge proposal for the greeter. It
facilitates an option to include a customized greeting string in the
login window.

The string is a maximum length of 255 bytes and may include any of the
following variables:
%n - nodename - ie: spanky
%h - FQDN - ie: spanky.mydomain.com
%s - system - ie: Linux
%r - release - ie: 3.18.11-200
%m - machine - ie: x86_64

To display the default greeting string, include the following in
lightdm-gtk-greeter.conf:
show-greeter-string = true

To display a customized greeting string, include the above and the
following (or any desired string) in lightdm-gtk-greeter.conf:
greeter-string-text = Custom string on %h running %s kernel version %r

If this option is selected, the hostname is no longer displayed in the
panel menu.

I was going to add an option to hide the user image but I see that it's
already been added.

I've included the patch for this. It's based on the trunk source from 25/4/2015

Thanks

I do have the same needs, while a little different, as I need to support markup.
So my patch and didn't support the %h, %n, ...

However it's done against 2.0.2 so more up to date.
Two key configuration were added !

message : a greeting message that is always showed. It support markup and could be a string or a filename which contains multiline markup.
message-locked : An addition to message (so message must be defined for this one to be showed) which is printed only when lightdm is used as a lock screen.

Ps : I didn't find how to use glade-3 with the greeter-menu-bar library inside the glade3, so I had modify the glade and -ui.h manually.
