I downloaded a couple greeters for LightDM, but I have not figured out how to enable them. Is there a way to switch greeter, either by graphical or command-line method?. I do not intend to change display manager, nor the background, but to change the layout and appearance of the login screen through a different "theme" (greeter is the name for LightDm themes). Thanks for your time.
Caution: Do not try this if you are not completely comfortable booting without X to repair lightdm configuration.

You'll then have to alter the Lightdm configuration to use the webkit greeter as opposed to unity (or whatever was default).
I believe there is a bug in the lightdm-webkit-greeter.conf file, where it refers to a webkit-theme called "default", that should be "webkit".
I currently use the webkit greeter to log in and can tell you that it is slow and unpolished at the moment.
Step by step:
(be prepared to fix the greeter configuration without a GUI if this fails)
bzr branch lp:lightdm-webkit-greeter
bzr merge lp:~elementaryart/lightdm-webkit-greeter/fixes-ubuntu-old
/autogen.sh (you'll have to install some dependencies here - probably only libwebkit-dev)
sudo make install
gksudo gedit /etc/lightdm/lightdm.conf
greeter-session=lightdm-webkit-greeter(remember the old setting as a fallback if you can't log in with your new settings)
gksudo gedit /etc/lightdm/lightdm-webkit-greeter.conf
- Set the
This should work to enable the default webkit login. Now you can edit the theme here:
gksudo gedit /usr/share/lightdm-webkit/themes/webkit/index.html
Edit: Another warning - you can seemingly lock yourself out of gnome if this does not work.
After you added you images to
/usr/share/backgrounds you need to open the Change Desktop Background dialog by right clicking in your desktop and selecting it.
After the dialog is open you can click the + to add the backgrounds you just copied to
Add all the images you have in
/usr/share/backgrounds, after you have done that you can select one and it will become your background.
If you are using 12.04 that same image will become the dynamic background for the Unity Greeter. If it does not follow the
Setting the dynamic switching off section of How do I change the wallpaper in LightDM? except instead of actually switching it off you use the command

Note to summarise:
Step 1: Add you custom wallpaper to `/usr/share/backgrounds
Step 2: Is conditional if you want your custom wallpaper to appear in the dynamic unity greeter (log in) in 12.04. Right click on your custom image and select "Properties" then select the Permissions tab. Navigate to the "Other" permission and change it from None to "Read-only". Note: If you don't do this Unity's default wallpaper will appear in Unity Greeter.
Step 3: Now you need to open the Change Desktop Background dialog by right clicking on your desktop and selecting it.
Step 4: After the dialog is open you can click the + to add the backgrounds you just copied to`/usr/share/backgrounds.
Step 5: Select your image to and change your desktop background`
Step 6: Log out and see the Unity Greeters background is your custom image
