Hi,
I'm running fbsd 4.1-Release & I'm having trouble trying to get
Xsession/.xsession configured to allow me to choose a window manager
from the kdm login screen (I belive I'd have exactly the same problem if
I was using xdm, though I haven't tried).
My Xsession file looks like:
#!/bin/sh -xv
for errfile in "$HOME/.xsession-errors" "${TMPDIR-/tmp}/xses-$USER"
"/tmp/xses-$USER"
do
        if ( cp /dev/null "$errfile" 2> /dev/null )
        then
                chmod 600 "$errfile"
                exec > "$errfile" 2>&1
                break
        fi
done
case $# in
1)
        case $1 in
        failsafe)
                exec xterm -geometry 80x24-0-0
                ;;
        esac
esac
startup=$HOME/.xsession
resources=$HOME/.Xresources
if [ -f "$startup" ]; then
        exec "$startup $1"
else
        if [ -f "$resources" ]; then
                xrdb -load "$resources"
        fi
        exec xsm
fi 

This should pick up the $1 parameter passed to it by kdm and then pass
that on to .xsession which looks like (for root):
#!/bin/sh -xv
#set default wm to kde
defaultwm=kde
#set the window manager to $1 if it was supplied
windowmgr=${1:-$defaultwm}
#start the respective window managers
case ${windowmgr} in
        kde|kwm|kdestart)
                WINDOWMANAGER=startkde
                ;;
        fvwm|fvwm2)
                WINDOWMANAGER=fvwm2
                ;;
        *)    WINDOWMANAGER=windowmgr   # default for unknown wm's

esac
exec $WINDOWMANAGER

but when I log in as root, it just goes back to the login screen.
(Xsession &
.xsession are both executable). The contents of .xsession-errors is:
+ break

case $# in
1)
        case $1 in
        failsafe)
                exec xterm -geometry 80x24-0-0
                ;;
        esac
esac

startup=$HOME/.xsession
+ startup=/root/.xsession
resources=$HOME/.Xresources
+ resources=/root/.Xresources

if [ -f "$startup" ]; then
        exec "$startup $1"
else
        if [ -f "$resources" ]; then
                xrdb -load "$resources"
        fi
        exec xsm  
fi
+ [ -f /root/.xsession ]
+ exec /root/.xsession fvwm
exec: /root/.xsession fvwm: not found  

The last line seems to imply that exec does not understand
/root/.session fvwm correctly.
If I edit Xsession and remove $1 from the line exec "$startup $1" and
change the last line of .xsession to exec startkde or exec fvwm, it
loads kde or fvwm correctly.
Also, if I run sh .xsession kde from an xterm, it runs .xsession & loads
kde correctly.
So why does it not work if .xsession kde is exec'ed from Xsession ?

I'm very confused by this - any help would be greatly appreciated.
Cheers,
Ian Moore
