- is demanding authentication (via `gksudo`-style dialogs) in situations where I've never seen them before: e.g., auto- and dismounting USB drives, sleep/suspend
- sleep/suspend via `Fn-F4` is broken (though C-A-D still works, with dialog=`Authenticate`)
- Network Manager disconnect is fully broken, with a message that suggests an authentication problem. (Fortunately it can be restarted from commandline.)
How to fix the MATE problems?
I noticed Update Manager's alert; since it signaled a kernel upgrade I did my backup box 1st. This 64-bit box has been running MATE on LMDE2 for several years, and currently runs (post-upgrade)

The problems are, in order of increasing severity:
1. When I automount a non-encrypted external (USB) drive, I get a `sudo`-style GUI dialog with title=`Authenticate` and headline=`Authentication is required to mount [drive description] (/dev/sdb1)`. I did not formerly observe this behavior. More annoyingly, I get the same dialog when I dismount the drive, which seems quite excessive.
Any suggestions for how to disable this? I'm not seeing any affordances in MATE Control Center regarding removable drives (though I could be missing something).
2. Suspend to RAM, aka sleep:
2.1. I can no longer sleep this box with the `Fn-F4` keychord. Formerly that just went to sleep; now I get the screenlock dialog. Authenticating that gets just gets me back where I was (i.e., an unslept desktop).
2.2. If instead I do C-A-D, and click button=Suspend on the subsequent dialog, I get ... the GUI dialog again! with same title=`Authenticate`, but with headline=`Authentication is required for suspending the system.` After I authenticate as demanded, the box usually sleeps, but on one case it instead logged me out.
This is even more annoying--suggestions for how to restore the previous behavior (i.e., just go to @#$%^&! sleep when I tell you !-) will be greatly appreciated.
3. Network Manager:
For several years I've noticed that this box will fail to reconnect to wireless on waking: the Network Manager tray icon will appear normal, but attempts to use wireless will fail. (Unlike my newer main workstation, which does not have this problem.) In the past, this has not been a problem, I just used the Network Manager GUI to dis/reconnect the desired SSID. However, post-upgrade, when I use the Network Manager GUI to disconnect, I get a dialog with title=`Disconnect failure`, subtitle=`Device disconnect failed`, and body=
