In windows xp, we can have a legalnotice popup by changing a particular key in the registry. (HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon) This causes a window to pop up before the login screen. Is there any way to get such a popup in linux as well? I'd like to do it in mandrake 10.1. It could even be a text based message, but it should require the user to 'press any key to continue....' and then go to the login screen. Can this be done?
