you can find the themes in /usr/share/mdm/html-themes.
copy one (the whole folder) that comes close to your wishes to a safe location in your $HOME and start hacking around.
i suspect most changes are to be made to the theme.css.
if you also need to edit the index.html itself, i highly recommend to leave all the scripts inside it untouched, only edit the html itself.
so maybe you need some html/css tutorial for that - try w3schools.com for starters, and then search your way to the better ones. stackoverflow.com usually have good answers to html/css questions.
in the end you have to copy the renamed folder back into /usr/share/mdm/html-themes - with root privileges.
then try the theme out in the above mentioned "Login Window" settings.
Thank you EDDY1 and Ondoho for coming,
Your posts were informative.
I happened to chance upon this
I customized the Login screen as to my wishes. Sometimes the internet is helpful while some other times, one can land up in mess.
That was nice of you guys, to come forward to help me.
Thank you & Regards
