Hey all,

I've got an ubuntu media center running XBMC, and I've got an idea. Right now, upon exiting XBMC (running in standalone session mode), GDM prompts for a login.

Instead, I'd like to be greeted with an application of my own allowing me to select the application to launch (XBMC, Spotify, Firefox etc.).

Now, this application doesn't need to handle logins as I can arrange for it to simply be run as my normal user, who can run all the applications. The application itself I reckon I should be able to put together using QT and C++. What I need to know however, is really how GDM and similar applications handle sessions (or alternatively, a better way to do it in my case).

Upon launching a session (say, the XBMC session, which runs xbmc --standalone), should my application "hide" in the background and wait until the application has terminated? What happens to GDM when I launch a normal session, and how does it appear when I exit my session again? Is it simply running in the background?

Hope this made any sense
