Created attachment 749287 [details]
Patch which allows expected background setting

Description of problem:

Attempts to configure in /etc/lightdm/lightdm-gtk-greeter.conf a background other than default usually end up with a black screen surrounding a greeter box.  For reasons not clear to me only PNG pictures with an alpha channel are acceptable (even if neither docs nor source seem to imply that this is the case).
OTOH "one-liner" patch, attached, make all kind of picture formats usable so one can use, for example, a JPEG format photo for a background and it displays
as expected.

Version-Release number of selected component (if applicable):

How reproducible:
all the time (but see below)

Additional info:
In my experience so far this afflicts, for mysterious reasons, only 32-bit binaries and the same pictures which will give a black lightdm-gtk background there will work just fine as expected on x86_64 system
Comment 1 Fedora End Of Life 2013-12-21 08:35:31 EST
This message is a reminder that Fedora 18 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 18. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '18'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 18's end of life.

Thank you for reporting this issue and we are sorry that we may not be 
able to fix it before Fedora 18 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior to Fedora 18's end of life.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.
Comment 2 Michal Jaegermann 2014-01-07 01:51:11 EST
lightdm-gtk-1.6.1-2.fc20 does not seem to suffer from the described affliction.  As a matter of fact sources of lightdm-gtk-1.6.1 include a code like the one from an attachment to this report although in a slightly different location.
