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.
