Hello Friends,

I have been working on WindowsXP, now I want to work on Linux platform and so need your help.

I want to change logon screen of OS. I want to build Custom GDM as I had made Custom GINA in WinXP and CP in Vista.
I want to show maximum 3 user accounts(in Windows my CUSTOM GINA used to read usernames from Registries) and 1 Administrator account on logon GUI.

I want to disable Mouse on Logon and only Keyboard should work on Logon.On Logon GUI I need to use IR Remote Control device to work for moving between textboxs of userid and pswd and entering pswd and then selecting OK.

The user will login by IR Remote and only Administration has keyboard to login.

After ADmin logins he has mouse and keyboard and sees all general OS environment.
When User logins he will not see any OS shell there will be a application which will run.

Please show me the direction how to proceed ahead and which distribution to use for it.I am thinking of trying openSUSE or Mandriva or Ubuntu.

Please tell me that Distro which provides good and free documents for developer.

If I use any of these distros then, Is the work to be done is same on all or not. eg. I want to change Login then for any Distros I will proceed in same way or there are different ways for doing the same thing in all Distros.

Somebody please throw some light on it.

Thanks.

It seems that are going to design your own Window Manager, or at least have to get involved with a lot of X-Windows functionality. For such a project the actual target Linux distribution is irrelevant, and the distribution for the development PC is merely a matter of personal preference (try out a few, and keep what you like). You have a lot of work ahead!
