Many thanks Warren, My knowledge of scripting is about 10% If you can help it would be very appreciated. I've found the xsession file I need to load. it is /opt/win4lin/bin/mergepro.xsession how could I load mergepro.xsession as the default? Thanks in advance Andrew. Here is the xclients file GSESSION="$(which gnome-session 2>/dev/null)" STARTKDE="$(which startkde 2>/dev/null)" # check to see if the user has a preferred desktop PREFERRED= if [ -f /etc/sysconfig/desktop ]; then . /etc/sysconfig/desktop if [ "$DESKTOP" = "GNOME" ]; then PREFERRED="$GSESSION" elif [ "$DESKTOP" = "KDE" ]; then PREFERRED="$STARTKDE" fi fi if [ -n "$PREFERRED" ]; then exec "$PREFERRED" fi # now if we can reach here, either no desktop file was present, # or the desktop requested is not installed. if [ -n "$GSESSION" ]; then # by default, we run GNOME. exec "$GSESSION" elif [ -n "$STARTKDE" ]; then # if GNOME isn't installed, try KDE. exec "$STARTKDE" fi # Failsafe. # these files are left sitting around by TheNextLevel. rm -f $HOME/Xrootenv.0 # Argh! Nothing good is installed. Fall back to twm { # gosh, neither fvwm95 nor fvwm2 is available; # fall back to failsafe settings [ -x /usr/bin/xsetroot ] && /usr/bin/xsetroot -solid '#222E45' if [ -x /usr/bin/xclock ] ; then /usr/bin/xclock -geometry 100x100-5+5 & elif [ -x /usr/bin/xclock ] ; then /usr/bin/xclock -geometry 100x100-5+5 & fi if [ -x /usr/bin/xterm ] ; then /usr/bin/xterm -geometry 80x50-50+150 & fi if [ -x /usr/bin/firefox -a -f /usr/share/doc/HTML/index.html ]; then /usr/bin/firefox /usr/share/doc/HTML/index.html & fi if [ -x /usr/bin/twm ] ; then exec /usr/bin/twm fi }
