Actually... We see the problem on our X-station 120's anytime the user 
failes his login.. I.E. invalid uid and/or password.   The xlogin stuff
that x-station manager is using is destroying the login envionment that
was setup by x-station manager see IBM apar IX19109 for symptoms and fix.

IBM says fix is in 2007 ?!?!?!   and can't even tell me when (if ever)
it will ship... all I get is mabey in 3.2!!!

We are at 3005 from 3003 upgrade.  And are running x-station manager 1.2
with the X11R4 servers on the X-120's.

I have told our users to get their logins correct the first time :-)

You can also CNTL-C out of the login, wait for the new login window and
try again... this will have the envionment set correctly...  

On an X-station, DO NOT RUN XINIT, This will start the server (again)
on the system console, IF THE XSTATION envionment variable is not set!. 

Here is what smit will place in the .profile if you have the 
initial interface set as "windows".  The xinit is bypassed if the
login fails, and does not start a xserver on the console.

----------------- .profile extension here --------------
TERMMTYPE=`tty | grep hft`
if [ -n "$TERMTYPE" -o -n "$XSTATION" ]
then
        if [ -f /usr/lpp/X11/bin/xinit ]
        then
                /usr/lpp/X11/bin/xinit
        fi
fi
--------------- .profile end ---------------------------

Seems to work for us.
