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.
