Mint is essentially repaired.  It works with the following desktop environments: KDE. Gnome, LXDE, LXQT, XFCE, and Mate.

     Gnome is a little bastardized.  The default configuration includes no logout button, obviously a problem.

     Adding one is non-standard.  Instead of the normal ALT+Right Click, Mint’s bastardized Gnome requires Windows+Alt+Right Click to add to a panel.  You can use that to add a Logout button to your panel then you will be good.

     All shells should be operational and most of the mailers on the other .deb derivatives are present on Mint.
