On Ubuntu 20.4.3 Alt+Left Ctrl do not function as Alt Gr on Finnish layout

On windows Swedish/Finnish keyboard layout left ctrl + left alt works as right alt (Alt gr). On Ubuntu this does not work by default.

For example on Windows: LeftCtrl + LeftAlt + '7' writes the '{' character.

On Ubuntu, on Finnish layout, nothing happens.

I do not except any 'solutions' where I have to set each individual special character button combination separately. It would probably help if I new what the term 'chooser' means. BTW: holding down alt gr and sliding my finger over all number keys gives:

1@£$5‚{[]}\

1 is not supposed to give anything but 5 should give the euro character which I am now unable to write.

Solution 1:

Linux uses XKB keyboard layouts, and most layouts (including Swedish and Finnish) defines AltGr by default as the key to access 3rd level symbols.

On Ubuntu you can use Tweaks to pick some other key. But AFAIK it's not possible to choose a key combination such as LeftCtrl+LeftAlt for that purpose.

Linux is not Windows, and when switching from one to the other you need to be ready to change your habits in some respects.
