I was just poking around the Entrance source and also the way xdm works
last week, while trying to see what can be done to solve the
Entrance+csh-as-login-shell issue.
Well, XDM goes thru /etc/X11/xdm/Xstartup as root, which login the user
in utmp, but DOES_NOT run the shell as a login shell, hence the startup
scripts are not read.
Then XDM run the /etc/X11/xdm/Xsession script as the user just logged
in. And my Xsession (slackware) does have this patch
<patch>
# Since xdm doesn't run a bash -login shell (or any other login shell)
# we should source these files to set up the user's environment.
profile=/etc/profile
userprofile=~/.profile
if [ -r $profile ]; then
source $profile 1> /dev/null 2> /dev/null
fi
if [ -r $userprofile ]; then
source $userprofile 1> /dev/null 2> /dev/null
fi
</patch>
Which loads the profile. So in this case, its not the login shell which
does it, but the Xsession script.
I have checked kdm, and kdm use the same sessreg (although in kdm this
is a function instead), and not /bin/sh -l.
I am still trying to see how I can change entrance to either use
/usr/X11R6/bin/sessreg or the sessreg.c from kdm, instead of /bin/sh -l.
