Questions about errors and duplicate messages in .xsession-errors

[Chris Green]

I seem to be seeing quite a lot of duplicate messages and errors in my
.xsession-errors file - as follows:-

    /etc/gdm/Xsession: Beginning session setup...

In particular why am I seeing that message "Warning: Only changing the
first 32 of 10 buttons" four times!  It means that xmodmap is being run
several times.

There also seems to be quite a problem with xsettings manager, is there
maybe a conflict between xfce and gnome for some reason?
