How can I change the default window manager for Xfce4?
For some reason,
xfwm doesn't run when I run xfce4 shell.

The easiest way I found to permanently change the default window manager is:
Download your desired WM.
Then go: system tools > preferences > startup applications.
Then click "add".
If you wanted, for example, to change your default WM to metacity, at "name" put "metacity" and at "command" put "metacity --replace". Click "add".
Log out > log in.
YourWindowManager --replace means xfwm4 has already started upon login and you are now stopping it to start a new window manager...that's working but there's a quicker and cleaner way as this guy explains taking kwin as his example.
XFCE starts the window manager specified in
/etc/xdg/xfce4/xfconf/xfce-perchannel-xml/xfce4-session.xml or, under xubuntu, in
In this file look for the
Client0_Command property and edit its value:
<value type="string" value="xfwm4"/> to
<value type="string" value="kwin"/> (obviously, replace "kwin" with your window manager of choice) You would need to go root. You could also copy and only edit that file in
/home/user/.config/xfce4/xfconf/xfce-perchannel-xml/xfce4-session.xml if you want the changes to only affect your userspace.
Because in XFCE it is common for us to save our session while logging out, don't forget to clean your session: Settings Manager->Session and Startup->Session tab->Clear saved sessions
Now you can logout and back in.
If you prefer a GUI solution, go to:
Settings >> Desktop Settings. In the Desktop Settings dialog, change the Window Manager to the manager of your choice.
This works in Linux Mint 20.2
