The answer says to enable Wayland. But does not say where to put those commands: Ctrl+Alt+T will open a terminal (command prompt-ish). The first line will open a hacker-like text editor. Do the edit and a menu in the bottom tells you how to save and close. "^" is ctrl key. Nano (the text editor) is made for computers without mice. @ubuntu@Linux4Everyone@linux
Yes, exactly, but with no green but white instead (even worse contrast).
I read the link now:

Also, this us a laptop monitor, no #display buttons, etc.
No, the PC had (!) already not been working anymore b/c some smart-ass HP support technician thought it necessary to update the BIOS as a 1st step in finding about why the replaced battery did not work longer than only 45 min. Now, the PC doesn't find a bookable OS on the 2 upgrade SSD's anymore, that had been working nicely for several years. What he should...
...have done, is to check and reset the max #BatteryCapacity, a manager from a specialist battery company informed me recently. The content on the upgrade SSDs is still unchanged, though.
