Using Another Window Manager
Xfce works nicely together with other window managers instead of xfwm4.
Replacing xfwm4 with the window manager of your choice is quite easy. Run
and save your session. The change will be applied on the fly.
Or, if the WM of your choice does not support the
--replace switch or you do not want saved sessions, use
xfconf-query -c xfce4-session -p /sessions/Failsafe/Client0_Command -n -a -t string -s "command_of_your_wm"
This needs a restart of your session.
To make the change on a global scope for all users which do not have this setting already in there private xfce configuration, alter
and change the appropriate value.
