We have 242 PCs with Ubuntu 12.04 running something like a kiosk mode using iDesk. The background image contains some info for the user but this is very static. Currently we are searching for a way to display dynamic infos to our users without the need to modify the background image.
So I think about a simply program which shows a windows with dynamic content - a website for example. But the window must be without any controls or styles and the user should not be able to move or resize this window.
Is there some program which could help to get this?
