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?

Hi alamuru420123,

Google Search: creating a popup in linux

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.

Code:

---

#!/usr/bin/wish
 #  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}

Hi

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.

Code:

---

> vi 45legalnotice

---

with

Code:

---

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".

Cheers.
