This is only a partial answer on the part 2: "How can I restore the working of AltGr key combinations to what I had before (documented above)?"
- Log in with an account able to do sudo.
- Issue the command
sudo dpkg-reconfigure keyboard-configuration
- This will take you through simlar screens as in the initial installation on a terminal-like console. In order to navigate to the
ok
option use the Tab key there. Use these settings on the screens (one question per screen)
- Das Modell der Tatstatur dieses Rechners: Generische PC-Tastatur mit 105 Tasten (international)
- Herkunftsland für die Tastatur: Deutsch
- Tastaturbelegeung: Deutsch (the first given choice)
- Taste, die als AltGr funktionieren soll: Der Standard für die Tastaturbelegung
- Compose-Taste: keine Compose-Taste
- Question about Ctl-Alt-Delete: Nein
These messages were shown on the terminal:
Your console font configuration will be updated the next time your system boots. If you want to update it now, run 'setupcon' from a virtual console.
update-rc.d: warning: start and stop actions are no longer supported; falling back to defaults

You have to reboot in order to make these settings effective.
However, two days later I encountered the same problem and I did not play with settings in between: AltGr-key combinations don't work any longer. Since my recipe how to overcome it requires quite some steps, some analysis how to prevent that would be wellcome. These are some system settings I figured out that they might tell something about the keyboard and the langugage settings but wha's wrong with them?

a@W530:~$
The really strange thing was that AltGr-key combinations still work when I am logged in with my administrative account. However, after I switch back to the normal user account, AltGr does not work any longer.
After struggeling quite some time with this problem I came about the command xev -event keyboard
. Strangely this gives different results when logged in with my normal account where AltGr does not work. Then this command returns
FocusOut event, serial 37, synthetic NO, window 0x3c00001,
mode NotifyGrab, detail NotifyAncestor
FocusIn event, serial 37, synthetic NO, window 0x3c00001,
mode NotifyUngrab, detail NotifyAncestor
KeymapNotify event, serial 37, synthetic NO, window 0x0,
keys: 99 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
wheras for the administrative account, where AltGr works and lets me reach the third level of the keyboard it returns:
KeyPress event, serial 37, synthetic NO, window 0x2c00001,
root 0x124, subw 0x0, time 7442734, (-338,129), root:(533,615),
state 0x0, keycode 108 (keysym 0xfe03, ISO_Level3_Shift), same_screen YES,
XKeysymToKeycode returns keycode: 92
XLookupString gives 0 bytes:
XmbLookupString gives 0 bytes:
XFilterEvent returns: False
KeyRelease event, serial 37, synthetic NO, window 0x2c00001,
root 0x124, subw 0x0, time 7442804, (-338,129), root:(533,615),
state 0x80, keycode 108 (keysym 0xfe03, ISO_Level3_Shift), same_screen YES,
XKeysymToKeycode returns keycode: 92
XLookupString gives 0 bytes:
XFilterEvent returns: False
This time there are two events: One when the Alt key is pressed and another one when it is released, as can be seen. If I would have pressed another key in addition with AltGr there pressing that other key and releasing it would make additional pressing and releasing events, it is similar to what is shown for shifted keys.
From the second answer to How to enable Alt-Gr on Ubuntu 16.04? we learned to change Alternate Chacter Key in System Settings > Keyboard > Shortcuts > Typing to AltGr. I have a German keyboard and the dialogs also speak Geran. Therefore I did this:
Starting with
I changed it to . But that did not work for me, even after a cold start of the computer.
