You can change it by editing the file
sudo -i scratch-text-editor /etc/lightdm/pantheon-greeter.conf
There you will find the line
default-wallpaper=/usr/share/backgrounds/elementaryos-default
Add a line to the file something like this:
default-wallpaper=/usr/share/backgrounds/168.jpg
Logout and you can see the change.

Yes, you can use Dconf-editor or Configurator and go to com.canonical.indicator.datetime and enable show-seconds
Or just paste this in your terminal:
gsettings set com.canonical.indicator.datetime show-seconds true
If you don't want to show seconds anymore you can use this:
gsettings set com.canonical.indicator.datetime show-seconds false

This is a security feature according to an explanation from another Stack Exchange community. Here are the two vulnerabilities solved by that feature:
this (sic) throttles login attempts, meaning someone can't pound the system as fast as it can go trying to crack it (1M attempts a sec? idk).
If it did it as soon as it verified your credentials were ...

A more convenient way to disable the guest login is:
Open System Settings and navigate to User Accounts.
Then select Guest Session and unlock the settings by authenticating with your user password:
You can now easily disable the guest session:

Just copy your wallpaper to /usr/share/backgrounds (you're going to need root privileges to do so) and then select your wallpaper from System Settings -Desktop - Wallpaper.
That should also change the login background.
In fact there is a bug where the login picture cannot be changed:

Unfortunately, there is no way to get the old screen. Both screenshots show pantheon-greeter but in different versions - and it's not possible to install older versions on Freya.
It's sad you'd consider to leave elementary OS because of the new greeter though.

I don't have dual graphics, but I do have a Haswell based machine with a GTX 960. I installed the release version of Loki and had slow, stuttering Nouveau graphics even though I had selected to install proprietary drivers during installation. This is what I did to fix it, afterwards I had fully accelerated binary drivers from Nvidia and a smooth, fast ...

There is a litte bash script called lightsOn on GitHub, which automatically checks on various apps, including fullscreen Flash and html5 video. (It works for me.)
Bash script managing screensaver and display power management (DPMS) on different conditions (fullscreen videos, specific applications, specific outputs).
To use the program save the ...

There is already a bug report for this problem, see Bug #1596377.
As suggested in the comments, the following workaround seems to fix the problem for some users:
sudo mv /etc/xdg/autostart/at-spi-dbus-bus.desktop /etc/xdg/autostart/at-spi-dbus-bus.desktop.backup
This worked for me, no delayed startup for the last couple of days (before it was ~2min after ...

This should work but it's more of a workaround than solution and I haven't personally tested it. Try changing your language to English in Settings and then use button "Apply to login screen, guest account and new users". Later on change back to Malay on your account and don't use the option to apply Malay to login screen.
The result should be English as ...

Run sudo -i scratch-text-editor /etc/default/acpi-support
Find and change POST_VIDEO=true to POST_VIDEO=false
Find and change SAVE_VBE_STATE=true to SAVE_VBE_STATE=false
Restart your laptop, issue should be solved.

To do this in a clean way, you will have to create a custom GNOME session file and a X Server session file (first, install openbox via sudo apt-get install openbox obconf menu of course). Let's take a look at the two files currently present:
/usr/share/xsessions/pantheon.desktop (X Server session file):
[Desktop Entry]
Name=Pantheon
Comment=This session ...

I suspect it is because login screen (greeter) and the desktop environment are a bit different entities. Lightdm starts the greeter, but desktop is handled by another entity, pantheon. They use same image only because system configures both at the same time when you change it.

xrandr allows us to reconfigure the X server without restarting it. Let's use it to set the correct resolution at startup.
Find out how the monitors are identified on your system. At the terminal, run the following:
xrandr -q | grep ' connected ' | awk '{ print $1 }'
My output is:
LVDS1
VGA1
Now I want to narrow down the above results to only the LG ...

I don't have a crystal ball, but I suppose to look for .Xauthority in your home folder, there might be a permission problem:
Press CTRL+ALT+F1 (but if you on mackbook do CTRL+FN+F1) to get to a prompt, and login.
Check the permissions and owner of your home directory: ls -l ~/.Xauthority
Change the owner of the file, if it is not yours, by chown username:...

Link default.desktop to pantheon-greeter.desktop:
cd /usr/share/xgreeters
sudo ln -s pantheon-greeter.desktop default.desktop

Try to use Caffeine.
A status bar application able to temporarily prevent the activation of both the screensaver and the "sleep" powersaving mode.
Install:
sudo add-apt-repository ppa:caffeine-developers/ppa
sudo apt-get update
sudo apt-get install caffeine
EDIT: Currently, this method doesn't work on Freya.

There is a problem with lightdm config. Start your system. When you stay at login screen, switch to console with Ctrl+Alt+F1 and log in with your username and password.
Then type:
sudo mv ~/.Xauthority ~/.Xauthority.back
Now type
sudo service lightdm restart
Switch to your login screen with Ctrl+Alt+F7 and try log in again.

Copy your wallpaper in /usr/share/backgrounds
then :
cd /usr/share/backgrounds
Just remove the symlink and add another one.
sudo rm elementaryos-default
sudo ln -s yourWallpaper.jpg elementaryos-default

You would have to download the code to the old greeter and compile it yourself, though I cannot guarantee that it would actually work.
Perhaps, if you are proficient enough with coding, you can fork and update the old greeter to work with newer releases.

Short answer:
To reduce the rate of login attempt
To prevent quick brute forcing of passwords.
This makes it take longer to guess passwords.
Greatly increase security
Comprehensive:
It's actually to prevent brute force attacks from trying millions of passwords per second. The idea is to limit how fast passwords can be checked and there are a number of ...

You dont' need your lightdm.conf file. I would rename the file as to make the system believe it isn't there. I only hae pantheon-greeter.conf and users.conf in my /etc/lightdm/ folder, and I don't have auto logins.
Make your /etc/lightdm/pantheon-greeter.conf look like this, too:
I really don't think you need a lightdm.conf for elementary. Try renaming the ...

Use dconf
Install dconf with the command:

Open dconf org --> gnome --> desktop --> background.

Now try again to change the background.

When I use that command it says:
No such schema "com.canonical.indicator.datetime"
Edit: the correct setting is:
(under dconf Editor)
io.elementary.desktop.wingpanel.datetime -> clock-show-seconds
