Tkinter and X11

[Philippe C. Martin]

Hi,

Is there anything that prevents tkinter from running prior to login to an
X11 session: as the X server is already up ?

Regards,

Re: Tkinter and X11

There should be no problem with this. After all, even the "greeter" is just an
X application. Depending on which login manager you use (xdm/kdm/gdm/whatever)
the details of getting your Tkinter app to actually be run will vary, though.
In gdm, it looks like adding it to the file /etc/X11/gdm/Init/default may be
the ticket.

It is probably best to run
app.tk.call("re name", "send", "")
in your program, for the reasons outlined in the send(n) manpage:
SECURITY
The send command is potentially a serious security loophole. On Unix,
any application that can connect to your X server can send scripts to
your applications. These incoming scripts can use Tcl to read and
write your files and invoke subprocesses under your name.

Thanks jeff,

I actually want that Tkinter application to be the greater: replace gdm....

Still feasible as far as Tkinter is conserned ?

Thanks and regards,

Philippe
