Hi Kevin,

Thank you for your response.

I know all these!  That's why I was surprised.  (I use KDM.)

To surprise you too :-), I've added the following line in my
.bash_profile

    export HELLO_KEVIN="Hi, How are you?"

and I restarted the machine (not only KDE but the entire Linux
system).  I then logged in from KDM.  Look at this:

  $ ls -lA .kde/env
  total 0
  $ env | egrep HELLO
  HELLO_KEVIN=Hi, How are you?
  $ su -
  Password:
  # ps -ef | egrep kicker
  furue     3884     1  0 08:42 ?        00:00:00 kicker [kdeinit]                
  root      4056  4033  0 08:43 pts/0    00:00:00 egrep kicker
  # cat /proc/3884/environ | tr '\0' '\n' | egrep HELLO
  HELLO_KEVIN=Hi, How are you?
  #

Not only konsole but also kicker gets my env.var.  I also found that
the process "/bin/sh /usr/bin/startkde" has the env.var. HELLO_KEVIN,
too (not shown above).  Since I use KDM, there's no chance that my own
evn.vars. are fed back to the KDE system, unless the KDE system sources
my .bash_profile .

I'm positive that my .bash_profile is sourced only when the bash is a
login shell:

   $ unset HELLO_KEVIN
   $ echo $HELLO_KEVIN

   $ bash
   $ echo $HELLO_KEVIN

   $ exit
   exit
   $ bash -l
   $ echo $HELLO_KEVIN
   Hi, How are you?
   $ exit
   logout
   $                                                

Seeing all these, the only conclusion I can reach is that the KDE
system sources my .bash_profile somewhere during its startup process
even when ~/.kde/env/   is empty.  Oh, and

   $ kde-config --path exe
   /home/amakihi/furue/.kde/bin/:/usr/bin/
   $ echo $HOME
   /home/amakihi/furue
   $

(Thanks for the command! )
As you can see, there's no other source than ~/.kde/env/
(And, of course, I'm not as crazy as to edit /usr/etc/ :-)

Right, but currently the environment extender mechanism seems to be
redundant.  Since I use KDM, there's no point prior to KDE startup
that an ordinary user can control.

| env > /tmp/kdeenv.txt

Thanks!  I did that, and here's the result:

    $ egrep HELLO /tmp/kdeenv.txt
    HELLO_KEVIN=Hi, How are you?
    $

Cheers,
Ryo
