XFCE works with Fedora 34 if you turn off compositing. See: 

Applications->Settings->Window Manager Tweaks->Compositor

To turn off globally (can be overridden by user), I created:

/etc/xdg/xfce4/xfconf/xfce-perchannel-xml/xfwm4.xml  with this added:

<?xml version="1.0" encoding="UTF-8"?>

<channel name="xfwm4" version="1.0">
  <property name="general" type="empty">
    <property name="use_compositing" type="bool" value="false"/>
  </property>
</channel>

So I'm not sure why so many of my desktops in Fedora have stopped working with x2go but I heavily suspect it is them transitioning all desktops to wayland. I know gnome still has an option to select xorg from the console but x2go does not provide any clarification on this kind of selection. Maybe if I understood how the server side selects the script to run to start the desktop depending on the selection from the client side I could help the package maintainers make things easier for x2go users. All I know for certain is: I was using XFCE desktop in Fedora 33 when I upgraded to Fedora 34 XFCE became unusable over x2go. I started trying other desktops and noticed they do not act right. Gnome over x2g on fedora 34 doesn't even start. KDE seems to have some issues. Mate seems to work.
