Ok, I read that section....not sure where I was "supposed" to find it
but I googled and found it here:
http://docsrv.sco.com:8457/en/KDEdoc/kdm/different-window-managers-with-kdm.html
Basically there needs to exist a case statement as follows:
case ${windowmgr} in
kde|kwm|kdestart)
WINDOWMANAGER=startkde
;;
fvwm|fvwm2)
WINDOWMANAGER=fvwm2
;;
fvwm95)
WINDOWMANAGER=fvwm95
;;
Also found a sample Xsession file for SuSe here:
http://forums.suselinuxsupport.de/lofiversion/index.php/t3151.html
This appears to confirm that I need the case statement listed above to
add items to the menu.
I want to remove items so I assume I need to remove lines from this
case statement. Since I want to remove default and custom as well as
failsafe I am looking for a line that says Custom) or custom)
I have grepped through /opt /etc /usr using "grep -ir custom *" and
see only one file which contains an entry in the case statement for
custom. it is the file referenced in that SuSe sample mentioned
above.
My first thought was to set it so that no matter what they selected it
woudl load the default of KDE so I replaced the exec commands for the
various cases with "exec startkde" which is what "default" was set to.
I then figured why not remove them from the menu altogether so I
commented out the cases in the case statement.
Rebooted and I still have all the options on the menu, and they work
too (log in as custom or failsafe, not as KDE) so it would seem that
kdm is not pulling its information from this file in /opt but perhaps
from the file referenced on the kdm help site
/usr/X11R6/lib/X11/xdm/Xsession however I do not see any reference to
custom or default in this file.
Thanks for any help you can offer.......below is the contents of
