    legalnotice popup in linux?

    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?

    The traditional way to do this is to edit /etc/motd.
    It shows up after the user logs in but before login runs.
    Motd also shows up after a remote user logs on.
    See motd(5).

    TCL/TK should be on most Linux distributions.

     #  Create the main message window
         message .m -text "Like Whatever" -background white
         pack .m -expand true -fill both -ipadx 100 -ipady 40
         #  Create the main menu bar with a Help-About entry
         menu .menubar
         menu .menubar.help -tearoff 0
         .menubar add cascade -label "Help" -menu .menubar.help -underline 0
         .menubar.help add command -label "About ..." \
              -accelerator "F1" -underline 0 \
              -command showAbout
         #  Define a procedure - an action for Help-About
         proc showAbout {} {
              tk_messageBox -message "Tcl/Tk\nHello Windows\nVersion 1.0" \
                   -title "About"
         #  Configure the main window
         wm title . "Legal Notice"
         . configure -menu .menubar -width 200 -height 150
         bind . "<Key F1>" {showAbout}
    I came in to the world with nothing. I still have most of it.

    We have quite a nice solution here, so I asked the responsible guy
    how they did it. Fairly simple actually:

    Since you would like a popup, I assumed you want this message to appear
    in the X11 system. This solution pops up the content of /etc/motd, as suggested
    by SirDice, after you have logged in.

    In /etc/X11/Xsesssion.d, create a new file, e.g.
    > vi 45legalnotice
    xmessage -center -file /etc/motd
    where in /etc/motd there is the legal notice (it then also is shown, when
    you remotely login, if configured correspondingly - as SirDice said).

    The man-page of xmessage also tell you, how to create buttons (e.g.
    if you want a "cancel" in addition to "ok".

    If the only tool you have is a hammer, you tend to see every problem as a nail.
