LightDM is the new login manager, and is meant to be themeable using HTML and CSS. How do I do that in Ubuntu 11.10? Can I use my own HTML file with my own text?

Things I've tried:

• I've spent a little while googling about and found nothing very useful so far, apart from how to change the background image.


• There is a launchpad answer referencing a theme directory but no clue as to what should go in the theme directory. It appears there used to be a /usr/share/lightdm/themes directory, but it is not on my system.


• I've spent a while looking but haven't found the files the current theme is in - if I could find that I could try copying and adapt it - I've done dpkg -L of both the lightdm and unity-greeter packages but not seen any HTML or CSS files.


• I have found the LightDM Reference Manual but that appears to be an API reference, not a configuration guide.


• I have tried browsing the LightDM code but can't find any sample HTML/CSS files.

Edit: To clarify I'd like to be able to edit an HTML file so I can add text to the login screen, not just change the fonts and background image. Sorry to @jokerdino who answered an unclear question.

Edit 2: Found a few more clues, but will have to play with them later.

• I have found /usr/share/lightdm-gtk-greeter/greeter.ui which is part of the lightdm-gtk-greeter package. It is an XML file that looks a bit like the login screen, but I'm not familiar with how to edit that.


• I have also found this sample HTML file which I can look at the source of (provided I don't let it time out - 5 seconds). It's linked to this javascript file which fakes lightdm for the web mockup. So maybe I can try putting a modified version of the HTML file in a directory and call that the theme directory ... But will have to try later - unless someone writes up some working instructions before then - hint, hint.
