The keyboard layout is set as English (US, intl., with dead keys) to deal with European lettering. This worked fine for a long time, but suddenly, the dead keys are not working in several programs. As in, when typing the dead key nothing happens. E.g. they don't work in browsers (checked in Firefox and Chrome) and in the Matrix Element program. However, they do work in other programs, such as Kate and LibreOffice.
Normally one can type an apostrophe (') by hitting that key and typing a space, but now the only way to get that character in those few programs is by pressing Alt Gr+' . The same thing for letters like é. Normally pressing '+e would work, now only Alt Gr+e works.

Apport bug report (aka ubuntu-bug xorg) did not work for the xorg package.

I'm not sure which package(s) this should be but 'xorg' is not a package that provides any relevant binaries. Moving to 'xorg-server'.

Status changed to 'Confirmed' because the bug affects multiple users.

Hi

I'm experimenting a very analog trouble.

I designed my own keyboard layout and my own .XCompose file to produce ancien greek characters such as α ά ὰ ὰ ᾴ ᾳ ἁ ᾁ ἀ ᾀ, … (I'm using 18.04 to type the present text). Ι've been using these keyboard and .XCompose file for several years now and they worked fine until I installed Ubuntu 20.04 on a new PC a few weaks ago.

When I hit a dead key, a little circle may get displayed on the screen, however not systematically. This little circle disappears when I hit the desired key, and the cursor returns to its previous location.

I'm very disapointed and ready to return to Ubuntu 18.04.
