I need some help getting the login screen configured.

My specific problem is that I don't want users to be able to enter a <space> in the username. However, since the <space> could be part of the username, I'm not going to try to block that.

But, I do have this problem that sometimes users accidentally press a <space> before typing in their username and don't realise it. So then they complain that their passwords doesn't work but it's actually because there is a leading space in their usernames (the users are very computer iliterate).

One solution may be to change the login screen to clear both the username AND password line when login fails. Currently it only clears the password line. I believe this should be possible because if you type in some chars in the username and password but don't login yet, the input blocks are cleared after a few minutes. Any idea how I can do this?

I've been editing /usr/share/mdk/dm/mdk-kde.xml but that seems to only specify what is displayed on the screen and not the behaviour.

Any ideas are welcome!

First off how many users? You could alway set up the login screen to show their names along with an Icon. This way they only need to select the icon with their name and then type in the password.

Yup, was just thinking of the same thing. Plus you get your cool little customizable icons next to your name!

Thanks, I'll try that. To start off with, there will probably only be two or three users, so an icon list would be good.
