Shift+m not working

This issue is similar to the un-answered seen here:

But I can say that the physical keyboard is not the problem
(Even bought the exact same make/model as I previous had - as the old was getting "nasty", and I thought that maybe was the cause)

But no, the "shift + m" will not produce anything
(neither left nor right shift)
With 'Caps Lock' on, the M key works, but also pressing shift will then not make lower case m (nothing shown).

The keyboard works fine on Windows 10

The OS-language is US-English, and I've tried (to no avail) with keyboard in US-English, Danish or Norwegian
(none of the three has "shift + m" working)

What is your xkb keyboard layout?

sudo nano /etc/default/keyboard

What about other shift + alphabets?
Are they working?

You may want to try updates - Ubuntu 20.04 - keyboard not working - Ask Ubuntu

It sounds like a driver issue.

Hi Aravisian,

First of all - thanks for helping out.

Hi ghostminator

Well yes - all other keys (shift + "others") are working.
Only the "shift + m" does not produce a "M"

Why is Danish sandwiching English?
Should this be:


Can you please run in terminal:

localectl list-x11-keymap-variants de

And relay the output?
