Re: Start only one program at login

Hi all:

I tried to make the setting apply globally by editing the
file /etc/X11/xinit/Xsession file by putting the sames two lines:

#####
metacity --sm-disable
exec firefox
#####

But it did not work. It gives me this error:

"Cannot start the session due to some internal error."

In my case, i would like any user to login to my system and can only use
firefox. Could someone please help me to fix it?

Regards,
Khem

I've wanted to this too but could not succeed. Thanks for the great tip.
May I further ask: is there an easy way to apply it to all users on the
system? I've tried putting the same thing in /etc/X11/xinit/Xsession
but it did not work.

Thanks,
Khem

Good.

You don't need two exec lines. You don't even need one:-)

Using "exec" _replaces" the shell running the script with the program
being called. Normally the called program is a child of the shell. For
the last program in a script it can be a tiny performance win to exec
it, since the shell is no longer needed.

Using "exec" with a "&" is harmless but also useless.

So I would write:

metacity --sm-disable &
exec gnome-terminal --window --full-screen

I normally try to avoid full pathnames to executables - things will just
break if the system layout is changed. Do you type full paths at your
shell prompt? Rarely I would hope:-) Scripts are no different.

Cheers,
