Shellx is restored to service.  X2Go was borked by an upgrade that was supposed to add support for gnome3-fallback and cinnamon sessions, neither of which are desktops available on this server.  Given that, I’ve downgraded to the previous working version.

Sound is still borked.  Fixing it is going to require downgrading kernel because drivers aren’t available for the current kernel.  Since this will most probably require multiple reboots, it’s going to wait until late Friday night.

Sound not reliant on gstreamer works but unfortunately that’s a minority of applications.
